DC braking when a fault occurs
Requirement:
Fault number and fault response are assigned
via p2100 and p2101.
Function:
1.
A fault occurs, which initiates DC braking
as response.
2.
The motor brakes along the down ramp to
the speed for the start of DC braking.
3.
DC braking starts.
DC braking initiated by a control command
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.
DC braking when the motor is switched off
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.
