4 Faults and alarms
4.2 List of faults and alarms
Alarm value (r2124, evaluate binary):
Alarm value 0:
The brake test was canceled as a result of a fault (brake opening time or brake closing time exceeded).
Bit 0:
The safe brake test was canceled by resetting the brake test selection.
Bit 1:
The safe brake test was canceled by resetting the brake test start.
Bit 2:
The brake, which was selected at the start of the brake test, has not been configured in p10202.
When starting the brake test, as a result of the test top selection, brake 1 is not configured as internal brake.
There is a brake test configuration error. In this case, alarm A01785 is also output.
Note:
SBT: Safe Brake Test
See also: p10202 (SI Motion SBT brake selection)
Remedy: - Check parameterization of the brake test (p10202).
- Check as to whether alarm A01785 is present, and if so, evaluate.
- Carry out a safe acknowledgment.
- If required, restart the brake test.
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
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
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.
