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,
