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).
