E1 V/f Pattern

◆ E1-01 Input Voltage Setting

Setting Ranges: 155.0 V ~ 255.0 V (208 V / 240 V Models)

310.0 V ~ 510.0 V (480 V Models)

Factory Defaults: 208.0 V (208 V Models)

240.0 V (240 V Models)

480.0 V (480 V Models)

Set the Input Voltage parameter (E1-01) to the nominal voltage of the connected AC power supply. This parameter adjusts the levels of

some protective features of the iQpump drive (i.e. Overvoltage, Stall Prevention, etc.). E1-01 also serves as the Maximum / Base Voltage

used by the Preset V / Hz curves (E1-03 = 0 ~ D).

◆ E1-03 V/f Pattern Selection

The iQpump drive operates utilizing a set V/f pattern to determine the appropriate output voltage level for each commanded speed. There

are 14 different preset V/f patterns to select from with varying voltage profiles, saturation levels (frequency at which maximum voltage is

reached), and maximum frequencies.

There are also settings for Custom V/f patterns that will allow the programmer to manually set (“Customize”) the V/f pattern using

parameters E1-04 through E1-13.

Using parameter E1-03, the programmer can select one of the preset V/f patterns or chose between a custom V/f pattern with an upper

voltage limit (E1-03 = “F: Custom V/f”) and a custom V/f pattern without a voltage limit (E1-03 = “FF: Custom w/o limit”).
