105
The inverter will set F8.07-F8.10 to be default standard motor parameter everty
time after motor rated data modified.
F8.12
Torque limit
Range: 50.0-200.0%
150.0%
This parameter is used to limit torque current outputted from speed adjustor.
Torque limit value 50.0-200.0% is percentage of inverter rated current; torque
limit=100%,i.e., set torque current limit is rated current of the inverter.
F8.13
Speed loop proportion gain
Range: 0.000-6.000
0.700
F8.14
Speed loop integral time constant
Range: 0.000-9.999
0.360
By F8.13, F8.14 you can set proportion gain and integral time of the speed
adjustor to change speed response characteristic of vector control.
F8.15
Motor stability coefficient
Range: 0-4
3
F8.16
Filter time displayed instead freq.
Range: 0-999
6
If surge happens or the motor run unstably, you can eliminate surge by
increasing F8.15.
F8.17 Motor speed correction factor
Range :0-9999%
100%
This parameter check display error, have no effect on the actual value.
6.10 Protection function parameter group: F9
F9.00
Waiting time for starting
again when power off
Range :0.0-20.0s(0 means do
not enable this function)
0
F9.01 Failure self-renew times
Range: 0-10
0
F9.02
Failure self-renew interval
Range: 0.5-20.0s
5.0s
During run process, failure will take place accidently due to load fluctuation
and the inverter will cut off output, here failure self-restoration function can be
applied in order to let the device continue to run. During self-restoration, the
inverter will try to resume running in speed checking restart mode but stop
outputting and failure protected if the inverter can’t resume running successfully
within set times. Self-restoration function will be shut down if failure self-restoration
times is set to 0.
When the inverter is under running, due to the system power supply it may
appear short time power failure so that the Inverter stops output, in order not to
suspend the equipment operation when the power on, please adopt F9.00 function.
After starting the inverter, though setting the parameter of F9.00, automatically
resume run as inspection speed start method.
