3.4.4 Operating the STO feature using MacTalk
If the motor has the Safe Torque Off option installed, The "STO – Safe Torque Off" tab
will be shown in MacTalk.
The actual status of both channels can be monitored on this tab. When green, the channel
is ON. Both channels must be ON at the same time in order to enable the motor.
When one or both of the channels are OFF, the Safe Torque Off is active and the motor
is disabled. The motor will behave according to the settings made:
Below the STO tab in MacTalk.

The motor will set both the General (bit 0) and the STO (bit 29) error bit. To get the
motor back in normal operation the STO channels must be ON, the error must be
cleared and an active operation mode must be selected.
Set Passive mode
Default = ON
The motor will go to passive mode. To get the motor back in normal operation the STO
channels must be ON and an active operation mode must be selected.

the STO channels are ON, a velocity value (>0 RPM) must be written into the velocity
