If it is set to 0, the hundreds place of P92.00 is
invalid.

During manual or power-on brake detection,
when the detected pulse count is greater than
P92.49 (non zero) but less than P92.11, A-LbE
is reported; when the detected pulse count is
greater than P92.11, if P92.49 is not zero,
A-obE is reported, and if it is zero, bE is
reported.
Description
0.50–1.00Hz
Note: In FVC mode, when the detected
feedback frequency is greater than the
brake release frequency P93.00, which lasts
P93.01, it considers that the brake slip fault
bE occurs.
0.000–5.000s
The value 0 indicates brake slip is not detected,
while a non-zero value indicates brake slip is
