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.
