5.7.1 Brake timing
The amplifier outputs this signal to automatically turn on or off the brake operation of the motor.
This signal turns excite or release the motor brake in accordance with the rotation command sent to the amplifier.
The control condition when the motor is stopped can be set by system para. 80.

Parameter setting
To allocate the brake timing output to the control output terminal, set (14) to the system para. If this signal is not allocated to the control
output terminal, this signal is deemed "always off."

Brake timing
The step to set the brake timing at the control output terminal is as follows:
1) Setting of control output terminal
Assign the value (14) corresponding to the brake timing to any one of the system para. from 31 to 35. If “ 14 ” is set at “ 31 ” , OUT1
terminal is the output terminal of brake timing.
2) Setting at stoppage
Set “ 2 ” or “ 3 ” at the system para. 81 to select the motor status while motor is stopping. When “ 3 ” is set at para. 81, the motor comes
to free-run status when activating the brake and the motor exciting noise is eliminated.
