Function: Drive Enable (Setting: 6A)

A digital input configured as an iQpump drive Enable input (H1-0x = 6A) will prevent the iQpump drive from executing a Run command
until it is closed. When the iQpump drive Enable input is open the digital operator will display:

If a Run command is closed prior to the iQpump drive Enable input being closed the iQpump drive will not run until the Run command is
cycled.

If the iQpump drive Enable input is opened while the iQpump drive is running, the iQpump drive will stop, using the method set by
parameter b1-03.

Function: Com / Inv Sel (Setting: 6B)

Function: Com / Inv Sel 2 (Setting: 6C)

The Com / Inv Selection function allows the user to switch the origin of the Run and speed command between the drive’s terminals and
the RS-485 / 422 port (and the embedded communication protocols) on the removable terminal board. When a digital input is
programmed for the Com / Inv Selection function (H1-0x = 6B) that input will function as follows:

Table 27 6B, COM / INV SEL

To switch the command source between the serial communication port and the control circuit terminals be sure to program the following
parameters:

• Set b1-01 (Auto Setpoint Reference Selection) to 1 (Terminals).
• Set b1-02 (Run Command Selection) to 1 (Terminals).
• Set H1-0x (Input Terminal Function Selection) to 6B or 6C.

The Com / Inv Sel 2 function will operate the same way except the logic is reversed. When a digital input is programmed for the Com /
Inv Selection function (H1-0x = 6C) that input will function as follows:

Table 28 6C, COM / INV SEL 2

Important: Switching the Reference and Run sources can only be done while the iQpump drive is stopped.

Function: Low City Press (Setting: 73)

<0034>

Indicates pressure status on the inlet to the pump. Function logic depends on parameter P4-21 (Low City Pressure Input Select).

■

Function: Reset Accum (Setting: 75)

<0034>

Closed: Volume accumulated will be reset to zero (and held at zero if digital input remains closed).

Option / Inv Function Input Status
