These parameters effectively give the position with a resolution of 1/2
32
ths of a revolution as a 48 bit number as shown below.
When the feedback device rotates by more than one revolution, the revolutions in Pr x.04 increment or decrement in the form of a sixteen bit roll-over
counter.
The marker offset corrects this position.
This parameter defines the mode of operation of the drive:
0 - HoSt: Host mode (Torque amplifier only)
1 - Enc.Only: Encoder only mode
Host mode uses an external position controller and an SM-SLM for the speed loop. The host controller will handle all SLM calculations for
initialisation. The UniSP acts as torque amplifier similar in operation as the MultiAx drive.
Enc. only mode uses the SLM module for speed feedback and nameplate data only.
