Siemens SINAMICS G150 Manual page 1383

Bit 25 = 1: the tested external brake was opened while the brake test was active.
Bit 26 = 1: during the active brake test, the test torque left its tolerance bandwidth (20 %).
Cause for alarm value bit 17:
Bit 0 = 1: operation when selecting the brake test not enabled (r0899.2 = 0).
Bit 1 = 1: external fault occurred (e.g. the brake test that has already started is canceled by the user).
Bit 2 = 1: when selecting the brake test a brake is closed.
Bit 3 = 1: when determining the load torque a brake is closed.
Bit 4 = 1: a fault with a stop response has occurred (e.g.. OFF1, OFF2 or OFF3).
Bit 5 = 1: when selecting the brake test the axis speed setpoint is too high.
Bit 6 = 1: the actual speed (r0063) of the axis is too high (e.g. brake does not hold during the brake test).
Bit 7 = 1: incorrect speed controller mode (e.g. encoderless speed control or U/f operation).
Bit 8 = 1: closed-loop control not enabled or function generator active.
Bit 9 = 1: control does not switch over to the brake test (e.g. because PI speed control has not been parameterized).
Bit 10 = 1: torque limit reached (r1407.7, r1408.8).
Note:
SBT: Safe Brake Test
Remedy: - Remove the fault cause.
- Carry out a safe acknowledgment.
- If required, restart the brake test.
Re bit 17 = 1 with bit 6 = 1 or bit 23 = 1:
If the brake closing time of the motor holding brake (p1217) has been set too low, then at the start of the brake test,
the brake is closed too late. The brake closing time should be adapted (p1217).
A01785 SBT brake test configuration error
Message value: %1
Message class: Safety monitoring channel has identified an error (10)
Drive object: VECTOR_G
Reaction: NONE
Acknowledge: NONE
Cause: Error when parameterizing the brake test.
In this configuration, the brake test cannot be started or cannot be started without error.
Alarm value (r2124, interpret decimal):
1:
No motion monitoring functions have been enabled.
2:
Two internal brakes were configured (p10202).
4:
No internal brakes were configured (p10202).
8:
The brake test is configured for an internal brake, however the safety brake control is not enabled (p9602/p9802).
16:
The safe brake test and Safety without encoder are simultaneously enabled (p9306/p9506). This is not permissible.
32:
The safe brake test and vector u/f control have been enabled. The safe brake test is not possible in this control mode.
Note:
SBT: Safe Brake Test
Remedy: Check parameterization of the brake test.
F01786 SCC signal source changed
Message value: -
Message class: Safety monitoring channel has identified an error (10)
Drive object: VECTOR_G
Reaction: NONE
Acknowledge: IMMEDIATELY
Cause: The signal source in p10235 or p10250 was changed.
