7-01 Speed PID Droop
Default value: 0 RPM Parameter type: Range (0–200 RPM)
Setup: All setups Conversion index: 0
Data type: Uint16 Change during operation: True
Adjust the speed reduction at 100% load.
7-02 Speed PID Proportional Gain
Default value: 0.015 Parameter type: Range (0.000–1.000)
Setup: All setups Conversion index: -3
Data type: Uint16 Change during operation: True
Enter the speed controller proportional gain. The proportional gain amplifies the error (that is the deviation between the feedback
signal and the setpoint). This parameter is used with parameter 1-00 Configuration Mode [1] Speed closed loop control. Quick control is
obtained at high amplification. However, if the amplification is too high, the process may become unstable.
7-03 Speed PID Integral Time
Default value: Size related Parameter type: Range (2.0–20000.0 ms)
Setup: All setups Conversion index: -1
Data type: Uint32 Change during operation: True
Enter the speed controller integral time, which determines the time the internal PID control takes to correct errors. The greater the error,
the more quickly the gain increases. The integral time causes a delay of the signal, and therefore a dampening effect, and can be used to
eliminate steady-state speed error. Obtain quick control through a short integral time, though if the integral time is too short, the process
becomes unstable. An excessively long integral time disables the integral action, leading to major deviations from the required reference,
since the process regulator takes too long to regulate errors. This parameter is used with [1] Speed closed loop control set in parameter
1-00 Configuration Mode.
7-04 Speed PID Differentiation Time
Default value: Size related Parameter type: Range (0.0–200.0 ms)
Setup: All setups Conversion index: -1
Data type: Uint16 Change during operation: True
