◆ b1 Sequence
The Sequence Group contains parameters associated with starting and stopping the Drive. Parameters involving the Run Command,
Speed Reference location, Stopping Method and Hand/Auto changeover are located in this group.
■
b1-01 Reference (Auto Setpoint) Source Selection
In order to run the iQpump drive and motor, the iQpump drive must receive a Run command and a Auto Setpoint command. Parameter
b1-01 specifies from where the Auto setpoint is received when in the “Auto” mode. Switching into the “Auto” mode can be done by
pressing the AUTO button on the digital operator while the iQpump drive is stopped.
Important: If a Run command is input to the iQpump drive but no corresponding Auto setpoint is input, the Run indicator on the digital
operator will turn on and the STOP indicator on the digital operator will blink.
If you want the iQpump drive to follow the “Hand Reference” set by the digital operator: Use the “Hand” mode by pressing the
hand key and set P5-01 = “1: Hand Reference (P5-02)”. The hand reference can then be entered into the P5-02 parameter.
The iQpump drive offers the ability to provide four types of “Auto Setpoint” reference sources. These Auto Setpoint reference sources
are determined by the setting of b1-01 and the drive set to “Auto” mode by pressing the Auto key on the digital operation.
Note: Prior to programming, it is recommended to first select the system units (P1-02) and the feedback device, Scaling
(P1-03). P1-03 will automatically scale the iQpump setpoint.
Example:
P1-02 = 1: PSI
P1-03 = 200, feedback range = 200 PSI.
If you want the iQpump drive to follow an “Auto Setpoint” set by the digital operator: Set b1-01 = “0: Operator” (factory default),
The Auto setpoint can then be entered into the U1-01 monitor parameter in the “-DRIVE-” menu.

Figure 2 Digital Operator Auto Setpoint
If you want the iQpump drive to follow an “Auto Setpoint” set by the analog input: Set b1-01 = “1: Terminals,” and connect a
potentiometer or external signal to the iQpump drive. Refer to Figure 3 for connection diagram for the setpoint potentiometer.
