• Set 0% to J95 (Brake-release torque) excluding brake-release at zero speed.

If releasing the brake at zero speed is needed under vector control with speed sensor, please use the
After releasing the brake (BRKS ON), operating for a while, and then applying the brake
to stop the motor, if it is required to release the brake again (BRKS ON), turn the inverter's run
command OFF and then ON.
The brake is not released during auto-tuning (stop mode).
■ Check brake “BRKE” (E01 toE05 data = 65)
If the status of the brake control signal BRKS fails to agree with the status of the brake check signal BRKE during
inverter operation, the inverter occurs alarm to stop with
er6
.
This signal is used as a feedback signal for the brake control signal BRKS. When the mechanical brake does not
operate, it causes the inverter to trip, applying the mechanical brake. The response delay time for BRKS and
BRKE can be adjusted with H180: Check-timer for brake operation.
