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
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
graph.
