SINAMICS S List Manual (LH1), 07/2007
A07932
Brake does not close
Drive object:
SERVO, VECTOR
Reaction:
NONE
Acknowledge:
NONE
Cause:
This alarm is output for r1229.5 = 1.
For r1229.5 = 1, OFF/OFF3 are suppressed to prevent the drive accelerating by a load that drives the motor -
whereby OFF2 remains effective.
See also: p1217 (Motor holding brake closing time), r1229 (Motor holding brake status word)
Remedy:
- check the functionality of the motor holding brake.
- check the feedback signal (p1222).
F07935 (N)
Drv: Motor holding brake detected
Drive object:
SERVO, VECTOR
Reaction:
NONE (OFF1, OFF2, OFF3)
Acknowledge:
IMMEDIATELY
Cause:
A motor with integrated motor holding brake was detected where the brake control has not been configured (p1215
= 0). The brake control configuration was then set to "motor holding brake the same as sequence control" (p1215 =
1).
Remedy:
None necessary.
See also: p1215 (Motor holding brake configuration)
Reaction upon N:
NONE
Acknowl. upon N:
NONE
F07940
Sync-line-drive: Synchronization error
Drive object:
VECTOR
Reaction:
OFF2
Acknowledge:
IMMEDIATELY
Cause:
After synchronization has been completed, the phase difference (r3808) is greater than the threshold value, phase
synchronism (p3813).
OFF1 or OFF3 response, while the closed-loop phase control is active (r3819.6 = 1) or synchronism reached
(r3819.2 = 1).
Enable signal withdrawn (p3802 = 0), while the closed-loop phase control was active (r3819.6 = 1).
Remedy:
If required increase the threshold value phase synchronism (p3813) for synchronizing the line supply to the drive.
Before OFF1 or OFF3, complete synchronizing (r03819.0 = 0).
Before withdrawing the enable signal (p3802 = 0), reach synchronism (r3819.2 = 1).

A07941
Sync-line-drive: Target frequency not permissible
Drive object:
VECTOR
Reaction:
NONE
Acknowledge:
NONE
Cause:
The target frequency is outside the permissible value range.
Alarm value (r2124, interpret decimal):
1084: Target frequency greater than the positive speed limit, f_sync > f_max (r1084).
1087: Target frequency less than the negative speed limit, f_sync < f_min (r1087).
Remedy:
Fulfill the conditions for the target frequency for line-drive synchronization.
See also: r1084 (Speed limit positive effective), r1087 (Speed limit negative effective)
A07942
Sync-line-drive: Setpoint frequency is completely different than the target frequency
Drive object:
VECTOR
Reaction:
NONE
Acknowledge:
NONE
Cause:
There is a considerable difference between the setpoint frequency and the target frequency (f_set <> f_target). The
deviation that can be tolerated is set in p3806.
Remedy:
The alarm automatically disappears after the difference that can be tolerated between the setpoint and target fre-
quencies (p3806) is reached.
