Motor Torque Off
The Motor Torque Off (MTO) function provides a method to remove torque-generating energy
from the motor to stop the motor from rotating by using an input on the removable
terminal block.
WARNING:
The MTO function removes motion-producing
power from the motor and must be considered in vertical load applications.
When the MTO signal is active (Off or open circuit), axis operation is disabled until the
fault is cleared.
Motor Torque Off Detection and Recovery Timing Diagram
Check the I.Axisxx.MotorTorqueDisabled tag to determine whether the axis is in the MTO
state.
When MTO is triggered, the fault is latched. Even when the MTO input signal has
recovered, a rising edge on O.Axisxx.ResetFault is required to clear the axis fault.
