A01781 SBT brake opening 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 open the brake during the brake test was exceeded.
Possible causes:
- during the brake test the drive went into a fault condition, and therefore the brake was closed by the drive.
- for an external brake, the feedback signal "Brake closed" was signaled too long (p10230.5, p10235).
Alarm value (r2124, interpret binary):
Bit 0 = 1:
Internal brake was not able to be opened.
Bit 1 = 1:
External brake was not able to be opened.
Note:
SBT: Safe Brake Test
Remedy: - carry out a safe acknowledgment.
- restart the brake test (p10230.1, p10235.1).
