
Please take precautions when enabling STO functions as servo drive will lose control
over the motion of the motor. Motor might dropped under gravitational pull (vertically
mounted load) or moved when external forces are applied to it. Alternatively, motor
with holding brake can be chosen.

STO is not meant to cut off the power supply of the servo drivers and motors
completely. Please power off and wait for a few minutes before starting maintenance
work.

It is recommended to use an isolated power supply for STO signal input as any
current leakage might cause STO malfunction.

Please remove the shorting connector from the STO port and use the provided STO
cable if the function is required.
