User Constant Tables
5-
21
Motor Constant Constants: E
The following settings are made with the motor constant constants (E constants): V/f characteristics and motor
constants.
V/f Pattern: E1
User constants for V/f characteristics are shown in the following table.
* 1. The factory settings depend on the Inverter capacity.
* 2. The factory setting will change when the control method and the Inverter capacity is changed.

To set V/f characteristics in a
straight line, set the same val-
ues for E1-07 and E1-09. In this
case, the setting for E1-08 will
be disregarded.
Always ensure that the four fre-
quencies are set in the follow-
ing manner:
