Starting
frequency of
direct start
Starting frequency of direct startup is the initial
frequency when the VFD starts. See P01.02 (hold
time of starting frequency) for details.

A proper starting frequency can increase the torque
during startup. Within the hold time of starting
frequency, the output frequency of VFD is the
starting frequency, and then it runs from the starting
frequency to the target frequency, if the target
frequency (frequency command) is below the
starting frequency, the VFD will be standby rather
than running. The starting frequency value is
unlimited by the lower limit frequency.
Setting range: 0.0–50.0s

P01.03
DC brake current
before start
During starting, the VFD will first perform DC brake
based on the set DC brake current before startup,
and then it will accelerate after the set DC brake
time before startup elapses. If the set DC brake
time is 0, DC brake will be invalid.
The larger the DC brake current, the stronger the
brake force. The DC brake current before startup
refers to the percentage relative to rated VFD
current.
