Data type:
Uint32
The integrator provides an increasing gain at a constant error between the setpoint and the feedback signal. The integral time is the time
needed by the integrator to reach the same gain as the proportional gain.
21-23 Ext. 1 Differentiation Time
Default value:
0.00 s
Setup:
All setups
Data type:
Uint16
The differentiator does not react to a constant error. It only provides a gain when the error changes. The quicker the error changes, the
stronger the gain from the differentiator.
21-24 Ext. 1 Dif. Gain Limit
Default value:
5.0
Setup:
All setups
Data type:
Uint16
Set a limit for the differentiator gain (DG). The DG increases if there are fast changes. Limit the DG to obtain a pure differentiator gain at
slow changes and a constant differentiator gain where quick changes occur.

22-4* Sleep Mode
4.19.2
The sequence when running sleep mode in open loop:
1.
The motor speed is less than parameter 22-47 Sleep Speed [Hz] and the motor has been running longer than parameter 22-40
Minimum Run Time.
2.
The drive ramps the motor speed down to parameter 1-82 Min Speed for Function at Stop [Hz].

Description
Feedback is detected together with the
speed.
Feedback is not detected, only sleep
speed and time are checked.
Only feedback is detected.
