Siemens SINAMICS G150 Manual page 1381

Note:
- The test must be performed within a defined, maximum time interval (p10003, maximum of 8760 hours) in order to
comply with the requirements as laid down in the standards for timely fault detection and the conditions to calculate
the failure rates of safety functions (PFH value). Operation beyond this maximum time period is permissible if it can
be ensured that the forced checking procedure is performed before persons enter the hazardous area and who are
depending on the safety functions correctly functioning.
Remedy: Initiate test stop (BI: p10007).
A01780 SBT When selected, the brake is closed
Message value: Following brakes are closed: %1 bin
Message class: Safety monitoring channel has identified an error (10)
Drive object: VECTOR_G
Reaction: NONE
Acknowledge: NONE
Cause: When selecting the brake test or starting the brake test, not all of the brakes were open.
Alarm value (r2124, interpret binary):
Bit 0 = 1:
The internal brake is closed.
Bit 1 = 1:
The external brake is closed (p10230.5, p10235.5, p10202).
Note:
The alarm is also issued, if a brake has not been configured in p10202.
SBT: Safe Brake Test
See also: p10202 (SI Motion SBT brake selection), p10230 (SI Motion SBT control word), p10235 (SI Safety Control
Channel control word S_STW3B)
Remedy: Open all brakes and reselect the brake test (p10230.0, p10235.0).
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
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).

A01782 SBT brake test incorrect control
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 brake test was canceled as a result of incorrect control.
