2.12.10 Phase controller
The phase controller is needed to ensure phase-synchronous running and drift-free standstill.
Parameter setting
1. Assign
MCTRL_nPosSet_a to a signal source that provides the phase-angle difference
between the set and actual phase-angles.
2. At
MCTRL_nPosLim_a enter a value > 0.
3. Set
MCTRL_bPosOn_b =TRUE.
4. Use C0254 to set the phase controller gain > 0.
– Before you set C0254, select a P-gain for the n-controller as high as possible under C0070.
(^ 2-45)
– During operation increase C0254, until the drive shows the desired control behaviour.

Phase controller influence
The output of the phase controller is added to the speed setpoint.
• If the actual phase is lagging, the drive is accelerated.
• If the actual phase is leading, the drive is decelerated, until the desired phase synchronisation
is achieved.
The influence of the phase controller consists of:
• Phase difference multiplied by the P-gain V
p
(C0254).
• Additional influence of an analog signal at MCTRL_nPAdapt_a .
(V
p
= C0254  MCTRL_nPAdapt_a / 16384)
• Limitation of the phase controller output to ± MCTRL_nPosLim_a .
Limiting of the phase-angle controller output
This limits the maximum catch-up speed of the drive in the event of large phase differences.
