Remedy
Check that the control cabinet design and cable routing are both in
compliance with EMC regulations.
Check as to whether an inadmissible voltage, e.g. 230 V, is connected
at the Control Unit digital output.
Fault acknowledgment
1. Select STO, and then deselect again.
2. If it cannot be acknowledged, replace the Control Unit.
Depending on the fault value, check the following:
10, 11: p1278 ≠ 0, brake not connected, cable interrupted or ground
fault
20: Short-circuit in the brake winding
30, 31, 40: Brake not connected or a short-circuit in the brake winding
50: Fault in the Safe Brake Relay, in the Control Unit or in the Power
Module.
Check and correct the parameterization of the motor holding brake:
The following settings can result in this message:
● p1215 = 0 and p9602 = 1.
● p1215 = 3 and p9602 = 1.
Corrective maintenance (Page 331)
1. Switch off the Control Unit power supply and then on again.
2. If it cannot be acknowledged, replace the Control Unit.
Acceptance tests for the safety functions (Page 209)
1. Switch off the Control Unit power supply and then on again.
2. If it cannot be acknowledged, replace the Control Unit.
Check the PROFIBUS or PROFINET configuration of the safety slot
on the master side and on the Control Unit.
Check the PROFIsafe configuring in the higher-level control.
● Alarm value r2124 = 1:
In the higher-level F control, remove the PROFIsafe configuring,
or enable PROFIsafe in the drive.
● Alarm value r2124 = 2:
In the higher-level F control, configure the appropriate PROFIsafe
telegram.
1. Check that the control cabinet design and cable routing are in
compliance with EMC regulations.
2. Switch off the Control Unit power supply and then on again.
1. Recommission the safety functions.
2. If this is not successful, then replace the Control Unit.
