Astraada DRV-24 frequency inverters Function Parameters
31
Detailed instruction of parameters
Applying low carrier frequency is contrary to
the above, too low carrier frequency will cause
unstable running, torque decreasing and surge.
The manufacturer has set a reasonable carrier
frequency when the inverter is in factory. In
general, users do not need to change the
parameter.
When the frequency used exceeds the default
carrier frequency, the inverter needs to derate
10% for each additional 1k carrier frequency.
Setting range:1.0~15.0kHz
Motor
parameter
autotuning
0: No operation
1: Rotation autotuning
Comprehensive motor parameter autotune
It is recommended to use rotation autotuning
when high control accuracy is needed.
2: Static autotuning 1(autotune totally); It is
suitable in the cases when the motor can not
de-couple form the load. The antotuning for
the motor parameter will impact the control
accuracy.
3: Static autotuning 2(autotune part
parameters); when the current motor is motor
1, autotune P02.06, P02.07, P02.08
0:Invalid
1:Valid during the whole procedure
The auto-adjusting function of the inverter can
cancel the impact on the output voltage of the
inverter because of the bus voltage fluctuation.
Function
restore
parameter
0:No operation
1:Restore the default value
2:Clear fault records
3: Lock all function codes
Note: The function code will restore to 0 after
finishing the operation of the selected function
code.
Restoring to the default value will cancel the
user password, please use this function with
caution.
P01 Group Start-up and stop control
0:Start-up directly:start from the starting
frequency P01.01
1:Start-up after DC braking: start the motor
from the starting frequency after DC braking
(set the parameter P01.03 and P01.04). It is
suitable in the cases where reverse rotation
may occur to the low inertia load during
