Speed Response Of Flux Weakening Area; Apr Gain; Gain Value Of Apr Feed Forward; Apr Curve Time - Delta C2000 series User Manual

 For the spindle application, the adjustment method is
1. It is used to adjust the output voltage when exceeding rated frequency.
2. Monitor the output voltage
3. Adjust Pr.11-21 (motor 1) or Pr.11-22 (motor 2) setting to make the output voltage reach motor
rated voltage.
4. The larger number it is set, the larger output voltage you will get.

Speed Response of Flux Weakening Area


Settings
 It is used to control the speed in the flux weakening area. The larger value is set in Pr.11-23, the
faster acceleration/deceleration will generate. In general, it is not necessary to adjust this
parameter.

APR Gain


Settings
 Kip gain of internal position is determined by Pr.11-05.

Gain Value of APR Feed Forward


Settings
 For the position control, if it set a larger value in Pr.11-25, it can shorten the pulse differential and
speed up the position response. But it may overshoot.
 When the multi-function input terminal is set to 37(ON), this parameter can be set as required. If
this parameter is set to a non zero value and adjust Pr.10-21 (PG2 Filter Time) to reduce the
position overshoot and pulse differential. If it is set to 0, it won't have overshoot problem in
position control but the pulse differential is decided by Pr.11-05 (KP gain).

APR Curve Time


Settings
 It is valid when the multi-function input terminal is set to 35(ON). The larger it is set, the longer the
