◆ b1-02 Run Command Selection
b1-02 = 0, Operator (factory default).
The iQpump drive comes factory programmed for Start and Stop from the Keypad.
The iQpump drive can be programmed to receiver a Run command from four different inputs: digital operator, terminals, serial
communications, or an option PCB.
If the Run command input is determined by the digital operator: Set b1-02 = “0: Operator,” and the HAND and OFF keys will be
used to provide the Run command to the iQpump drive.
b1-02 = 1, Terminals
If the Run command input is determined by the external terminals: Set b1-02 = “1: Terminals” and initiate an external Run
command by a contact closure between terminals S1 and SN. Refer to
Figure 8. for the connection diagram of the external Run
command.
Note: To use the external terminals requires the iQpump drive to be set to “Auto” mode by pressing the Auto key.
Select between 2-wire and 3-wire control operation by doing the following:
2-Wire Control The factory default setting is for 2-wire operation. In the 2-wire configuration a closure between S1 and SN will be
interpreted as a Forward Run command by the drive.
Figure 1.6
Figure 6. 2-Wire Control
3-Wire Control When any of the multi-function digital input parameters, H1-01 through H1-05, is set to 0, terminals S1 and S2 become
Run and Stop, respectively. The multi-function digital input that was set to 0 will function as a Forward / Reverse input for the iQpump
drive. When the Forward / Reverse input is open the iQpump drive will run in the Forward direction and when the input is closed, the
iQpump drive will run in the Reverse direction.
In 3-wire operation a momentary closure (> 50mS) of S1 will cause the iQpump drive to run provided that S2 is held closed. The iQpump
drive will stop anytime the S2-SN connection is broken. If the 3-wire configuration is implemented via a 3-wire Initialization (A1-03 =
“3330: 3-Wire Initial”), then terminal S3 becomes the Forward / Reverse input.
Note: Reverse operation is disabled in the iQpump drive; however, in 3-wire control, one of the multi-function digital inputs
needs to be programmed to 0. Otherwise, the 3-wire control will not work.
