Starting

direct start
Starting frequency of direct startup is the initial
frequency when the inverter starts. See P01.02 (hold
time of starting frequency) for details.
Setting range: 0.00–50.00Hz

A proper starting frequency can increase the torque
during startup. Within the hold time of starting
frequency, the output frequency of inverter 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 inverter will be standby rather
than running. The starting frequency value is
unlimited by the lower limit frequency.
Setting range: 0.0–50.0s
DC brake current
before start
During starting, the inverter 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 inverter
current.
Setting range of P01.03: 0.0–100.0%
Setting range of P01.04: 0.00–50.00s
