Description
Motor de-excitation time (calculated after quick commissioning)
The inverter can trip due to an overcurrent during DC braking if the de-excitation time is
too short.
DC braking activation (factory setting: 0)
Signal source to activate DC braking
0 signal: Deactivated
•
1 signal: Active
•
Configuring DC braking (factory setting: 0)
0 No DC braking
4 General release for DC braking
5 DC braking for OFF1/OFF3
14 DC braking below the starting speed
DC braking braking current (factory setting 0 A)
DC braking duration (factory setting 1 s)
Requirement:
p1231 = 4 and p1230 = control command, e.g.
p1230 = 722.3 (control command via DI 3)
Function:
1. The higher-level control issues the
command for DC braking, e.g. using DI3:
p1230 = 722.3.
2. DC braking starts.
If the higher-level control withdraws the com-
mand during DC braking, the inverter inter-
rupts DC braking and the motor accelerates to
its setpoint.
Requirement:
p1231 = 5 or p1230 = 1 and p1231 = 14
Function:
1. The higher-level control switches off the
motor (OFF1 or OFF3).
2. The motor brakes along the down ramp to
the speed for the start of DC braking.
3. DC braking starts.
