2 Parameters
2.2 List of parameters
Description:
Sets the delay time for pulse suppression.
After OFF1 or OFF3, the pulses are canceled, if at least one of the following conditions is fulfilled:
- the speed actual value falls below the threshold in p1226 and the time started after this in p1228 has expired.
- the speed setpoint falls below the threshold in p1226 and the time started after this in p1227 has expired.
Dependency:
Refer to: p1226, p1227
Notice:
When the motor holding brake is activated, pulse cancellation is additionally delayed by the brake closing time
(p1217).
Description:
Sets the signal source to activate DC braking.
Dependency:
Refer to: p1231, p1232, p1233, p1234, r1239
Note:
1 signal: DC braking activated.
0 signal: DC braking deactivated.
Description:
Setting to activate DC braking.
Value:
0:
No function
4:
DC braking
5:
DC braking for OFF1/OFF3
14:
DC braking below starting speed
Dependency:
Refer to: p0300, p1232, p1233, p1234, r1239
Note:
The function can only be used for induction motors (p0300 = 1).
For p1231 = 4:
The function is activated as soon as the activation criterion is fulfilled.
- the function can be superseded by an OFF2 response.
Activation criterion (one of the following criteria is fulfilled):
- binector input p1230 = 1 signal (DC braking activation, depending on the operating mode).
- the drive is not in the state "S4: Operation" or in "S5x".
- the internal pulse enable is missing (r0046.19 = 0).
DC braking can only be withdrawn (p1231 = 0) if it is not being used as a fault response in p2101.
In order that DC braking is active as fault response, the corresponding fault number must be entered in p2100 and
fault response p2101 set = 6.
