Commissioning steps
Step 0: Condition as supplied and
initialization
The "Safe Torque Off" function is always active and cannot be deactivated.
During the booting process, the drive system is
in the "STO" operating status;
i.e., the output stage has been switched off via two channels.
After the booting process, the safety function "Safe Torque Off" is active.
When the drive is switched from operating mode to parameter mode, the
functionality of the "Safe Torque Off" function is maintained, i.e. according to
the selection, the "Safe Torque Off" function becomes active or not.
Step 1: Connecting and wiring the
"Safe Torque Off" function
The connection and wiring of the "Safe Torque Off" function depends on the
option used to make the selection at the drive or the drive connection box
KCU02.
The "Examples of application for IndraDrive Mi" chapter shows the different
options of selection and wiring.
The table below shows the dependances of the wiring of the optional safety
technology module:
