5.8.1 Holding Brake Interlock Signal
This output signal can be output for interlocking motor circuit power status and motor rotation
speed.
■
Setup Procedure
The brake signal is output from 1CN-1(2). Delay time tB ( X 10 ms) from the brake turns ON until
the Servomotor drives OFF can be set in user constant Cn-0012. The following shows the Servo
ON signal and power supply timing.
