*1. Set a brake release frequency higher than the starting frequency (b082).
*2. If the set current is too low, sufficient torque may not be provided when the brake is released.
In any of the following cases, the Inverter trips and outputs the brake error signal (BER). (Brake error:
E36)
•The output current is lower than the release current after the brake release establishment wait time
(b121) elapses.
• When the brake confirmation (BOK) signal is used, the brake confirmation signal does not turn on
within the brake confirmation wait time (b124) during acceleration, or does not turn off within the
brake confirmation wait time (b124) during deceleration; or the brake confirmation signal turns off,
although the brake release signal is output.

0.00 to 5.00:
Brake wait time for Set a time required for the output current to
release reach the rate of the release current after
reaching the release frequency.
0.00 to 5.00:
Brake wait time for Set a mechanical delay time from when the
acceleration release signal is output until the brake is
released.
0.00 to 5.00:
Brake wait time for Set a mechanical delay time from when the
stopping release signal is turned off until the brake is
closed.
0.00 to 5.00:
