p29592[0...n] Deragging forward speed / Derag fw spd
Access level: 3 Calculated: - Data type: FloatingPoint32
Can be changed: T Scaling: - Dynamic index: DDS, p0180
Unit group: 3_1 Unit selection: p0505 Function diagram: -
Min:
-210000.00 [rpm]
Max:
210000.00 [rpm]
Factory setting:
500.00 [rpm]
Description: Defines forward speed setpoint for deragging.
Note
The actual speed setpoint is limited by minimal(P1080) and maximum(P1082) value.
If both forward speed(P29592) and the time of duration(P29596) are 0, forward rotation will not perform in each cycle.
p29593[0...n] Deragging reverse speed / Derag rev spd
Access level: 3 Calculated: - Data type: FloatingPoint32
Can be changed: T Scaling: - Dynamic index: DDS, p0180
Unit group: 3_1 Unit selection: p0505 Function diagram: -
Min:
-210000.00 [rpm]
Max:
210000.00 [rpm]
Factory setting:
500.00 [rpm]
Description: Defines reverse speed setpoint for deragging.
Note
The actual speed setpoint is limited by minimal(P1080) and maximum(P1082) value.
If both reverse speed(P29593) and the time of duration(P29597) are 0, reverse rotation will not perform in each cycle.
p29594[0...n] Deragging ramp up time / Derag rup
Access level: 3 Calculated: - Data type: FloatingPoint32
Can be changed: T Scaling: - Dynamic index: DDS, p0180
Unit group: - Unit selection: - Function diagram: -
Min:
0.00 [s]
Max:
1000.00 [s]
Factory setting:
5.00 [s]
Description: Defines ramp time from 0 to forward/reverse speed setpoint for deragging.
Note
Too short ramp up time for deragging may trigger F7902, and speed jump may occur.
The minimal time is upon the inertia of motor and power stage.
p29595[0...n] Deragging ramp down time / Derag rdn
Access level: 3 Calculated: - Data type: FloatingPoint32
Can be changed: T Scaling: - Dynamic index: DDS, p0180
Unit group: - Unit selection: - Function diagram: -
Min:
0.00 [s]
Max:
1000.00 [s]
Factory setting:
5.00 [s]
Description: Defines ramp time from forward/reverse speed setpoint to 0 for deragging.
Note
Speed jump may occur if ramp down time is too short, and that may trigger the fault of DC-link overvoltage.
The minimal time is upon the inertia of motor and power stage.
