1.0 Overview:
This software adds full range DC injection, as well as a DC injection command as a multi-function input
selection. DC injection causes DC current to flow in the motor windings, which aligns the motor poles and
provides deceleration and/or holding torque.
A trim control feature for the frequency reference (similar to the GPD515/G5 function) is also included.
This allows for increasing or decreasing (trimming) of the frequency reference by a programmed amount
through a multi-function input contact closure.

*1: It is not possible to set n045 less than n046 or to set n046 greater than n045. . If n045 < n046 due to
setting by communication, an “oP9” alarm will be displayed.
3.0 Additional Multi-function Input Settings (n050 ~ n056):
Setting Description
28 DC Injection Command
29 Trim Control Increase
30 Trim Control Decrease
When n050 ~ n056 = 28, the corresponding input terminal (S1 ~ S7) is used for commanding DC
Injection.
When n050 ~ n056 = 29/30, the corresponding input terminals (S1 ~ S7) are used for the frequency
reference trim control increase/decrease function.
