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.

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

FU1? PreExTime
14 1.0 sec
Factory Default:
1.0 sec
When you set ON to the operation command (FWD,
REV), the inverter conducts pre-exciting automatically
for the time specified by this parameter.
l After FU1-14 [Pre-excitation Time] elapses the
inverter starts normal operation in the following
