◆ H2 Digital Outputs
■ Terminal Function Selections
Setting Range: 0 to 42
Factory Defaults: H2-01 = “40: Pump 2 Control”
H2-02 = “41: Pump 3 Control”
The iQpump drive has two multi-function outputs. By programming parameters H2-01 and H2-02, the user can assign specific functions
to each output. Below is a table with a complete list of all of the digital output functions. Because the iQpump drive is a dedicated pump
controller, the digital outputs described in this section only relate to the pump specific functions. Following the table is a more detailed
description of each of the pump related functions.
Table 16 Digital Output Functions
Function: During Run 1 (Setting: 0)
A “During Run 1”output will close whenever the Run command is provided and the iQpump drive is outputting voltage. This will include
deceleration and DC Injection.
Function: Zero Speed (Setting: 1)
The “Zero Speed” output will close whenever the output frequency falls below the Minimum Frequency (E1-09).
Function: Fref/Fout Agree 1 (Setting: 2)
The “Fref/Fout Agree 1” output will close whenever the actual output frequency is within the Speed Agree Width (L4-02) of the current
Speed Command regardless of the direction.
