"B" Group: Fine Tuning Functions Section 3-6
When using the brake control function, assign the following signal functions to
intelligent input and output terminals as needed.
1. To input a signal indicating that the brake is released from the external
brake to the inverter, assign the braking confirmation signal (44: BOK) to
one of the terminal 1~7 (C001~C007)
2. Assign the brake release signal (19: BRK), which is a brake-releasing com-
mand, to one of the output terminal 11~12 (C021~C022). To output a signal
when braking is abnormal, assign the brake error signal (20: BER) to an
output terminal.
When using the brake control function, you are recommended to select the
sensorless vector control (A044=03) that ensures a high torque performance
