High-function General-purpose Inverter 3G3RX-V1 User’s Manual (I578-E1)
• Use this function to adjust the inverter output voltage as 100% of the voltage set in the Motor Rated
Voltage Selection (A082).
• You can avoid motor hunting by decreasing the value set in the Output Voltage Gain.
• Use this function to apply DC injection braking to the motor according to the load.
• Two types of DC injection braking are available: via a multifunction input terminal that is allocated to
07: DB (External DC injection braking), and automatic application at the time when the motor is
started or stopped.
Note, however that the use of DC injection braking may not be able to stop the motor due to the
moment of inertia of the motor load.
