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.

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.
