3.5.43.7 Angle controller
The angle controller is required to achieve angular synchronism and drift−free standstill.
) Note!
Select a configuration with digital frequency coupling in C0005 since this serves to
link all important signals automatically. On this basis the system can be optimised.
Activating the angle controller
1. Configure a signal source with C0894, which provides the angular difference between setpoint
and actual angle (see "Digital frequency configuration under C0005).
2. Select a value > 0 at the MCTRL−PHI−LIM input.
3. Trigger the input MCTRL−PHI−ON with HIGH (e.g. with FIXED1).
4. Set the gain of the angle controller > 0 in C0254 (see chapter 3.5.43.4)
– Before setting C0254, select an as high as possible P−gain for the n−controller in C0070.
– Increase C0254 during operation until the drive shows the required control response.
Influence of angle controller
The output of the angle controller is added to the speed setpoint.
l If the actual angle is lagging, the drive is accelerated
l If the actual angle is leading the drive is decelerated until the required angular synchronism is
achieved.
The influence of the angle controller consists of:
l Angular difference multiplied by the P−gain C0254
l Additional influence via analog signal at MCTRL−P−ADAPT
l Limitation of the angle controller output to ±MCTRL−PHI−LIM
Limitation of the angle controller output
This limits the max. speed−up of the drive at high angular differences.
