9.6.1.6 Option "Actual MCTRL position received at mains switch-off"
The encoder position can be saved with mains failure protection in the controller. For this purpose,
the bit 0 has to be set in C02652 .
• From version 14.00.00 , the "Actual MCTRL position received at mains switch-off" option can also
be accessed in the »Engineer« via the parameterisation dialog for the basic function Homing
(depending on the set position encoder system).
• If bit 0 is set in C02652 , the actual position of the motor control is saved in the controller (not in
the memory module) and thus remains known to the drive control after mains switching.
The following overview shows the actual position after mains connection depending on the setting
C02652 /bit 0, C00490 , C00422 , C00925 (if resolver is selected) and the existence of the reference
information:
9.6.2 Requesting the operating mode
Request for the "referencing" operating mode by means of the MCK control word :
If the MCKInterface is connected upstream to the Motion Control Kernel and if the operating mode
is requested at the L_MckCtrlInterface FB, the wOperationMode and bOperationMode_1...8 process
inputs are available.
