Failure to comply may cause death or serious injury. Sudden Movement Hazard. The digital operator sets the frequency reference and Run command.
Application n b Prohibit programming during run It is not possible to enter the Programming Mode as long as the drive output is active. Zero Speed Control is enabled for the time set in parameter b provided b is set to 0.
When the output frequency falls below the setting of b Run Command at Power Up Determines whether an external Run command that is active during power up will start the drive. For these control modes.
DC Injection Braking is enabled for the time set in parameter b If b is set to a smaller value than parameter E minimum frequency. Run Command Selection 2 Refer to b Run Command Selection 1 on page For safety reasons.
Proper precautions must be taken to ensure that the area around the motor is safe prior to powering up the drive. Failure to comply may cause serious injury. If a Run command is issued at power up. If b is set to 1 and an external Run command is active during power up. E Min. Disabled when set to 0.
Do not set this parameter higher than the level necessary to hold the motor shaft. Used to completely stop a motor with high inertia load after ramp down. Used to stop a coasting motor before restarting it or to apply braking torque at start. Increasing the current level will increase the amount of heat generated by the motor windings.
Application E Min. If b is set lower than the minimum frequency E Increase the value if the motor still coasts by inertia after it should have stopped. As DC Injection can generate a fair amount of noise. Be aware that sudden acceleration may occur when using this method of Speed Search with relatively light loads. This function allows for the development of more flux to facilitate starting machines that require high starting torque or motors with a large rotor time constant.
Both methods are explained below and followed by a description of all relevant parameters. When a momentary loss of power occurs. Figure 1. When power returns. As long as the current is higher than the level set to b Magnetic Flux Compensation Value Sets the magnetic flux compensation at start as a percentage of the no-load current value E For PM motors. If the current falls below b When Speed Search is started it reduces the output frequency starting from either the maximum output frequency or the frequency reference while increasing the output voltage using the time set in parameter L For induction motors.
Speed Search The Speed Search function allows the drive to detect the speed of a rotating motor shaft that is driven by external forces and start the motor operation directly from the detected speed without first stopping the machine.
Thereby the Speed Search may start not at the end of L but even later. After power is restored. If L is lower than the time set to parameter b Speed Estimation is executed in the two steps described below: Step 1: When Speed Search is applied automatically with the Run command. Do not use this method if the motor is one or more frame size smaller than the drive. If there is not enough residual voltage in the motor windings to perform the calculations described above. After that.. Baseblock Time L b Figure 1.
If the power interruption is longer than the minimum baseblock time set to L If the there is a change in the cable length between the drive and motor. Method 1. The drive then outputs the detected frequency and increases the voltage using the time constant set to parameter L while looking at the motor current. The Speed Search type must be selected in parameter b independent of the activation method. Step 2: Current Injection Current Injection is performed when there is insufficient residual voltage in the motor after extended power losses.
External Speed Search commands are ignored. Automatically activate Speed Search with every Run command. This feature injects the amount of DC current set to b to the motor and detects the speed by measuring the current feedback. Use Current Detection in these instances. The output frequency is reduced if the current is higher than the level in b When the current falls below b The time entered into b will be the time to decelerate from maximum frequency E to minimum frequency E Speed Search Deactivation Current Sets the operating current for Speed Search as a percentage of the drive rated current.
Lower this value if the drive has trouble restarting. If external Speed Search 1 or 2 is already enabled by a digital input. For this operation mode. After external baseblock is released.
Normally there is no need to change this setting. After momentary power loss. Activate Speed Estimation Closed: Disabled This setting starts operating the drive at the minimum output frequency when the Run command is entered. Use the input functions for H1-oo in Table 1. Method 5. Application Method 2. Method 4.
To activate Speed Search by a digital input. Refer to L Momentary Power Loss Operation Selection on page When the number of maximum fault restarts in parameter L is set higher than 0. After automatic fault restart. The drive begins running the motor once Speed Search is complete. Enabled This setting performs Speed Search when the Run command is entered. Method 3. Activate Speed Search using the digital input terminals.
The output current during Speed Search is automatically limited by the drive rated current. Speed Search Restart Current Level Sets the current level at which Speed Estimation is restarted as a percentage of drive rated current to avoid overcurrent and overvoltage problems since a large current can flow into the drive if the difference between the estimated frequency and the actual motor speed is too big when performing Speed Estimation.
Changing this value can help reduce the output current during Speed Search. Default Determined by o Available control modes for parameter b vary by drive model: This parameter can be used to delay the Speed Search operation. Speed Search Delay Time In cases where an output contactor is used between the drive and the motor. If the motor speed is relatively slow when the drive starts to perform Speed Search after a long period of baseblock. Increase the setting only if an overvoltage fault occurs when the drive restarts the motor.
Disabled Setting 1: Enabled The drive detects the motor rotation direction to restart the motor. To enable the timer function. Increase the wait time if problems occur with overcurrent. Number of Speed Search Restarts Sets the number of times the drive should attempt to find the speed and restart the motor. Delay Timers The timer function is independent of drive operation and can delay the switching of a digital output triggered by a digital input signal and help eliminate chattering switch noise from sensors.
Off-Delay Time b sets the on-delay time for switching the timer output. If the number of restart attempts exceeds the value set to b Speed Search Restart Detection Time Sets the time for which the current must be above the level set in b before restarting Speed Search.
Only one timer can be used. The following diagram illustrates the timer function operation: Multi-function Contact Input: The timer function switches off when the timer function input is open for longer than the value set to b Timer Function On-Delay. An on-delay and off-delay can be set separately. Current Detection Speed Search Setting 1: Speed Estimation Speed Search Note: With P control. Application u b5: Only use D control when absolutely necessary. Flow rate sensor Thermocoupler. Synchronous control is Tachometer performed using speed data from other machinery as the target value Maintains constant pressure using pressure feedback.
D control tends to amplify noise on the deviation signal. If parameter b is set to 1 or 2. It minimizes the offset between target and feedback value that typically remains when pure P control is used. The integral time I time constant determines how fast the offset is eliminated. This way the D portion of a PID controller provides a braking action to the controller response and can reduce the tendency to oscillate and overshoot.
Pressure sensor Keeps flow at a constant level by feeding back flow data. Maintains a constant temperature by controlling a fan with a thermostat. If b is set to 3 or 4. Differential Feedback The second PID feedback signal for differential feedback can come from the sources listed below. The differential feedback function is automatically enabled when a differential feedback input is assigned. D control is disabled by setting b to zero seconds.
Larger values will tend to reduce the error but may cause oscillations if set too high. Integral Limit Setting Sets the maximum output possible from the integral block as a percentage of the maximum frequency E The PID feedback is D controlled.
To turn off the integral time. Longer time settings improve the response but can cause vibrations. PID disabled Setting 1: The PID input is D controlled. If the integral time is set too short.
Program b to apply a limit to the integral output and suppress this oscillation. The shorter the integral time set to b The PID feedback loss detection function detects broken sensors or broken sensor wiring. This function is set up using parameters b to b Application No.
The following figure illustrates the working principle of feedback loss detection when the feedback signal is too low.
Feedback high detection works in the same way. It should be used when PID control is enabled to prevent critical machine conditions e. Increasing this time constant may reduce the responsiveness of the drive. Set to a value larger than the cycle of the resonant frequency. Feedback loss can be detected in two ways: This function is set up using parameters b Neither a fault nor an alarm is displayed on the digital operator and the drive will continue operation.
Setting 5: Feedback loss fault.
PID Feedback Loss Detection Selection Enables or disables the feedback loss detection and sets the operation when a feedback loss is detected. If the PID feedback value exceeds the level set to b for longer than the time set to b Digital output only. Feedback loss alarm. The drive will continue operation. Feedback Loss Alarm If the PID feedback value falls below the level set to b for longer than the time set to b The PID feedback must fall below this level for longer than the time set to b before feedback loss is detected.
The alarm and outputs reset when the feedback value leaves the loss detection range. The output resets when the feedback value leaves the loss detection range. Feedback Loss Fault If the PID feedback value falls below the level set to b for longer than the time set to b The drive resumes operation when the PID output or frequency reference is above b for longer than the time set to b An example of PID Sleep operation appears in the figure below.
The drive will resume operating when the PID output or frequency reference rise above the PID Sleep operation level for the specified time. The PID feedback must exceed this level for longer than the time set to b before feedback loss is detected. The drive goes into Sleep mode if the PID output or frequency reference is smaller than b for longer than the time set to b The parameters necessary to control the PID Sleep function are explained below.
When the setpoint changes quickly. Parameter b acts as a bipolar limit. Disabled Parameter b is not used as the PID setpoint. Enabled Parameter b is used as PID setpoint. User Defined Parameters b and b determine the units and resolution used to display the values the setpoint in b The lower limit is disabled when set to 0. Application Parameter b determines the display value when the maximum frequency is output and parameter b determines the number of digits.
Frequency Reference Monitor U displays the frequency reference value. The setting value is equal to the number of decimal places.
Dwell Time at Stop Parameter b determines the frequency that is held for the time set in b during deceleration. Dwell Function The Dwell function temporarily holds the frequency reference at a predefined value for a set time then continues accelerating or decelerating. The drive in which Droop control is activated shifts the load from one motor to another by automatically reducing the speed when the torque reference rises. Dwell Reference. Dwell Time at Start Parameter b determines the frequency that is held for the time set in b during acceleration.
The figure below illustrates how the Dwell function works. Droop Control CLV. The Dwell function helps prevent speed loss when starting and stopping a heavy load with induction motors. Droop control must be activated in one of the drives controlling these motors. Droop control automatically balances the load level between two motors driving the same load.
A setting of 0. Reduce the setting if the reaction time is too long. The gain is set as a percentage of the maximum output frequency. To activate Zero Servo mode. Droop Control Limit Selection No.
Enabled u b9: The drive goes into Zero Servo mode and holds the current position when the motor speed falls below the level set to parameter b The drive accelerates when the input assigned to trigger the Zero Servo function is released and the Run command is still present. Application Motor A runs faster than B. Zero Servo will not hold the load in place if the Run command is switched off.
To prevent this increase the Zero Servo gain b Enter the amount of deviation allowable from the desired position to trigger Zero Servo. Increase the value if the response is too slow and the deviation from the zero position rises too high when load is applied.
Decrease the value if vibrations occur during Zero Servo operation. If such loads need to be held in place for long periods.
The Run command must remain on when using the Zero Servo function. When the Zero Servo command has shut off. Tuning 1. For example. Deceleration time parameters always set the time to decelerate from maximum output frequency to 0 Hz. Acceleration and Deceleration Times n C to C Decel Times 1 to 4 Four different sets of acceleration and deceleration times can be set in the drive by digital inputs.
Tuning C parameters set the characteristics for acceleration. Acceleration time parameters always set the time to accelerate from 0 Hz to the maximum output frequency E Other parameters in the C group cover settings for slip compensation.
The motor 2 selection function cannot be used with PM motors. The drive can switch between different acceleration and deceleration times automatically.
Acceleration and deceleration times selected by digital inputs have priority over the automatic switching by the frequency level set to C Output Frequency. Fast Stop Time Sets a special deceleration used when a select group of faults occur e. A momentary closure of the digital input will trigger the Fast Stop operation; it does not have to be closed continuously.
The drive cannot be restarted after initiating a Fast Stop operation until after completing deceleration, clearing the Fast Stop input, and cycling the Run command.
