8.6.1.6
Option "Actual MCTRL position received at mains switch-off"
The encoder position can be saved with mains failure protection in the inverter. For this purpose, the
bit 0 has to be set in
•
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
, the actual position of the motor control is saved in the inverter (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
/bit 0:
