3.4.2 Connect STO (P1)

Safe torque off (STO) is a safety function that prevents the drive from delivering

power to the motor, which can generate torque.

STO Enable and STO Return must be connected to enable CDHD operation. The

STO Enable signal voltage must be 24 VDC.

Using the supplied mating connector, connect the STO interface.

If the application does not require STO functionality, connect pin 4 to pin 1, and

pin 3 to pin 2.
