YASKAWA TM.iQp.07 iQpump Controller Programming Manual 147

Digits 1 through 4 set the desired number to be displayed at maximum feedback level. Digit 5 determines the number of decimal places in

the displayed number.

If Digit 5 = 0 number format is XXXX

If Digit 5 = 1 number format is XXX.X

If Digit 5 = 2 number format is XX.XX

If Digit 5 = 3 number format is X.XXX

Example 1: 00145 (factory default)

P1-02 = 1 (factory default)

P1-03 = 145 psi (No decimal point)

Example 2: 11000 (one decimal point)

P1-02 = 1

P1-03 = 100.0 psi (one decimal point)

◆ Feedback Device

The iQpump Controller requires a feedback device (e.g. Pressure transducer, flow meter, etc.) to perform automatic system regulation.

Any analog 0~10 V or 4-20 mA feedback device can be used in combination with the iQpump controller.

■ Connecting a Feedback Device to the iQpump Controller

Note: The factory default setting for the iQpump controller is 4~20 mA feedback device connected to analog input A2.

◆ P1-04 Start Level

Setting Range: - 999.0 ~ 999.9 <0034>

Factory Default: 0.0

The iQpump drive can be configured to program the starting pressure for the system by programming the Start Level (P1-04). The units

for this parameter are determined by the System Units (P1-02).

If set to a negative value, the feedback level must drop by this amount below the setpoint.

<0034>

If P1-01 = 3, the function will stop all drives running on the network when the system fault occurs.<0034>

Function Description <0034>

Normal PI Control (b5-09 = 0).

When parameter P1-04 is set to a positive value, the feedback must drop below that value before the drive will wake up. When parameter

P1-04 is set to a negative value, the feedback must drop the P1-04 amount below the setpoint.

Inverse PI Control(b5-09 = 1).

When parameter P1-04 is set to a positive value, the feedback must drop above that value before the drive will wake up. When parameter

P1-04 is set to a negative value, the feedback must increase to the P1-04 amount plus the setpoint.
