SBT brake opening time exceeded

NONE
The maximum time (11 s) to open the brake during the brake test has
been exceeded.
Possible causes:
-- During the brake test, the drive has gone into a fault condition, and
therefore the drive closed the brake.
-- For an external brake, the feedback signal "Brake closed" was
signaled for an excessively long period of time (p10230.5, p10235).

Bit 0 = 1:
Internal brake was not able to be opened.
Bit 1 = 1:
External brake was not able to be opened.
Perform a safe acknowledgment.
Restart the brake test (p10230.1, p10235.1).
