u
Q1: Preset Setpoint
n Q1-01: PID Controller Setpoint 1
Sets the PID setpoint for the controller. The drive will use the system feedback signal and modulate the pump speed to regulate the feedback at the Q1-01 setpoint. The units for Q1-01 are selected by b1-01 and the scaling is set in parameter P1-03. This parameter is active when b1-01 (Reference Source) is set to 0 (HOA keypad).
No.

Q3: Output Current Limit
The drive reduces the frequency reference in an attempt to limit the output current. The current limit setpoint is determined by parameter P1-11. When the actual motor current rises above the setpoint, the frequency reference is reduced by a PI controller and the minimum output frequency reference is limited to fmin. The HOA keypad will display a "Current Limit Foldback" alarm when the current limit function is active.
n Q3-01: Output Current Limit Select
Enables and disables the output current regulator.
