Function and interface
Do not connect.
Inputs 1 and 2 for operating the STO function, which are 2
independent circuits. This input turns OFF the power
transistor drive signals in the Servo Drive to cut off the
current output to the motor.
A monitor signal is output to detect a safety function failure.
Connected to the ground terminal inside the Servo Drive.
