FU1-08: DC Injection Braking Frequency

FU1-09: DC Injection Braking On-delay Time

FU1-10: DC Injection Braking Voltage

FU1-11: DC Injection Braking Time

By introducing a DC voltage to the motor windings this function stops the motor immediately. 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.

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.
