1.2.2 Function mode of the safety modules
C00214
The code C00214 must comply with the plug−in safety module type so that the controller
is able to operate.
Disconnecting paths
The transmission of the pulse width modulation is safely (dis−)connected by the safety
module. Hence the drivers do not create a rotating field. The motor is safely switched to
torqueless operation (STO).

Safety status
When the controller is switched off by the safety module, the controller switches to the
"Safe torque off"device state.
ƒ "Controller in STO state" is entered into the logbook (0x00750003).
ƒ "Safe torque off active" is displayed in C00183.
