1.2.2 Function mode of the safety modules
The code C00214 must comply with the plug-in safety module type so that
the controller is able to operate.
The transmission of the pulse width modulation is safely (dis-)connected by
thesafetymodule.Hencethedriversdonot createarotatingfield. Themotor
is safely switched to torqueless operation (STO).

When the controller is switched off by a safety module, the ”Safe torque off”
status is set (C00183 = 101).
If internal errors of the safety modules are detected, the motor is safely
switched to torque-free operation (fail-safe status).
