• J71 can be used even under vector control with speed sensor.
• If using with zero speed control under vector control with speed sensor, set the J95 brake-release
torque to 0%.
• If the brake is released at zero speed, use torque bias.
• If the brake is applied (brake signal OFF) to stop the motor after releasing the brake (brake signal ON)
and performing operation, turn the inverter run command OFF and then back ON again in order to
release the brake (brake signal ON) to resume operation.
• The brake release signal is not output during auto tuning (stop mode).
