P01.05
Selection of starting mode
range:0~1
Factory default:0
0: start from start frequency
When the variable frequency drive starts running from the stop status, it is started directly from the
setting frequency of the starting frequency P01.06, and the setting time of P01.07 is kept at this
frequency, and then it is accelerated to the setting frequency to run according to the setting acceleration
time and acceleration mode.
In this starting mode, if the setting value of P01.09 is not 0, then DC braking is performed firstly and
then it is started from the starting frequency.
1: speed search starting
Firstly, the current rotating speed of the motor is identified, and then the smooth start is carried out
from the searched speed. It is suitable for starting large inertia loads, rotating motors and other
equipment.
P01.06
Starting frequency setting
range:0.00Hz~upper limit
frequency
Factory
default:0.50Hz
P01.07
Hold time of start frequency
range:0.0s~3600.0s
Factory default:0.0s
In order to ensure the motor torque when starting, please set a suitable starting frequency. The
starting frequency holding time is used for establishing sufficient magnetic flux during the motor starting
process. The starting frequency holding time is not included in the acceleration time.
P01.08
Starting DC brake
current/pre-excitation current
range:0.0%~100.0%
Factory
default:50.0%
P01.09
Starting DC braking
time/pre-excitation time
range:0.00s~30.00s
Factory
default:0.00s
When the setting value of P01.09 is greater than 0.00s, and the starting mode is selected to start
from the starting frequency, the variable frequency drive performs DC braking firstly, and then it starts
from the starting frequency, the DC braking current is determined by P01.08, and DC braking current is
a percentage relative to the rated current of the variable frequency drive.
