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".

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
