P3-12 Delta Setpoint Feedback Acc/Dec Changeover
Setting Range: 0.0 to 6000.0
Factory Default: 0.0
The iQpump drive can be configured for multiplex pumping operation. The acceleration (Acc) and deceleration (Dec) times can be
changed when the difference between the delta setpoint and feedback are within the programmed level in the Delta Setpoint Feedback
Acc/Dec Changeover (P3-12).
The acceleration and deceleration times during this changeover are programmed into C1-05 and C1-06, respectively.
This function is used to improve the pump regulation.
Setting P2-12 to a value of 0 will disable this function.
