4.2 List of faults and alarms
SINAMICS G130/G150
1482 List Manual (LH2), 07/2016, A5E03263479A
A01783 SBT brake closing time exceeded
Message value: Fault cause: %1 bin
Message class: Safety monitoring channel has identified an error (10)
Drive object: VECTOR_G
Component: None Propagation: GLOBAL
Reaction: NONE
Acknowledge: NONE
Cause: The maximum time (11 s) to close the brake during the brake test was exceeded.
Alarm value (r2124, interpret binary):
Bit 0 = 1:
Internal brake was not able to be closed.
Bit 1 = 1:
External brake was not able to be closed.
Note:
SBT: Safe Brake Test
Remedy: - When using an external brake, check that the feedback signal "brake closed" is correctly interconnected with the
control word of the brake test (p10230.5, p10235.5).
- When using an internal brake with external feedback signal, check whether the feedback signal is correctly
interconnected with the extended brake control.
- carry out a safe acknowledgment.
- restart the brake test (p10230.1, p10235.1).
A01784 SBT brake test canceled with fault
Message value: Fault cause: %1 bin
Message class: Safety monitoring channel has identified an error (10)
Drive object: VECTOR_G
Component: None Propagation: GLOBAL
Reaction: NONE
Acknowledge: NONE
Cause: The safe brake test was canceled as a result of a fault.
Alarm value (r2124, interpret binary):
Bit 17 = 1: fault in the brake test sequence (cause, see bits 0 ... 10).
Bit 18 = 1: the internal brake is closed. It must be open when the external brake is tested (p10202).
Bit 19 = 1: the external brake is closed. It must be open when the internal brake is tested (p10202).
Bit 20 = 1: not all brakes are open (p10202).
Bit 21 = 1: axis position during the brake test not valid due to parking axis.
Bit 22 = 1: internal software error.
Bit 23 = 1: the permissible position range of the axis was violated with the brake closed (p10212/ p10222).
Bit 24 = 1: the tested internal brake was opened while the brake test was active.
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) - or pulse enable was withdrawn (e.g.
STO selected or operation no longer enabled).
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).
