FU1-09[DC Injection Braking On-delay Time] is the inverter output blocking time before DC injection braking.

FU1-10[DC Injection Braking Voltage] is the DC voltage applied to the motor and is based on FU2- 33 [Rated Current of Motor].

FU1-11[DC Injection Braking Time] is the time the DC current is applied to the motor.

This function stops the motor immediately by introducing DC voltage to the motor windings. Selecting ‘DC-Brake’ in FU1-07 activates FU1-08 through FU1-11.

FU1-08[DC Injection Braking Frequency] is the frequency at which the inverter starts to output DC voltage during deceleration.

[DC Injection Braking Operation]

FU1-12: Starting DC Injection Braking Voltage

FU1-13: Staring DC Injection Braking Time

Inverter holds the starting frequency for Starting DC Injection Braking Time. The inverter outputs DC voltage to the motor for FU1- 13 [Starting DC Injection Braking Time] with the FU1-12 [Starting DC Injection Braking Voltage] before accelerating.
