Chapter 6 - Parameter description [FU1]

6-12

FU1-12: Starting DC Injection Braking Time
FU1-13: Staring DC Injection Braking Time










Inverter holds the starting frequency for Starting DC
Injection Braking Time. It 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.

























[Starting DC Injection Braking Operation]


Note: The DC injection braking function does not function

when either FU1-12 or FU1-13 is set to “0”.

Note: FU1-12 [Starting DC Injection Braking Voltage] is

also used as the DC Injection Braking Voltage for the
multifunction input when the multifunction input is set to “DC
braking”.


FU1-14: Pre-excitation Time




To set the time for pre-exitation (Flux gain time) before
starting Vector or Sensorless Vector control

After FU1-14 [Pre-excitation Time] elapses the motor

starts acceleration,
