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. Parameter Name Setting Range Default
Q1-01 PID Controller Setpoint 1 0.0 to 6000.0 0.0 PSI
n
Q1-02 to Q1-04: PID Controller Setpoint 2 to 4
Sets the PID Setpoint when the corresponding Multi Setpoint or Alternate Multi Setpoint digital inputs are closed.
No. Name Setting Range Default
Q1-02 to Q1-04 PID Controller Setpoint 2 to 4 0.0 to 6000.0 0.0
n
Q1-09: Setpoint MOP
Selects whether parameters Q1-01 to Q1-04 are changed via MOP using the Up and Down arrow keys on the HOA keypad.
No. Name Setting Range Default
Q1-09 Setpoint MOP 0, 1 0
Setting 0: Disabled
Setting 1: Enabled
u
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.
No. Name Setting Range Default
Q3-01 Output Current Limit Select 0, 1 0
Setting 0: Disabled
Setting 1: Enabled
n
Q3-02: Current Limit
Sets the value of the output current to which the drive will limit if the output current exceeds the value.
No. Name Setting Range Default
Q3-02 Current Limit 0.0 to 1000.0 A 0.0 A
n
Q3-10: Ripple Regulator Selection
Enables and disables the Single Phase power DC bus ripple regulator. This function will lower the output frequency if the DC
bus voltage ripple exceeds the value set in Q3-11.
No. Name Setting Range Default
Q3-10 Ripple Regulator Selection 0, 1 1
