CD040 Up/Down
Set Range: 0.01~2.50Hz Unit:0.01Hz Factory Setting:0.01
This parameter can be set in combination with CD073 for Up/Down of
external control and the speed of increase and decrease.
the step length of Up/Down=(the set value of CD040/0.01)× UP/DOWN speed
CD041 Starting Frequency
Set Range: 0.10—10.00 Hz Unit: 0.01Hz Factory Setting: 0.50
Starting frequency is the initial frequency when the inverter is started. If the
starting frequency is set to 4.0Hz, the inverter will run between 4.0 Hz and the
maximum operating frequency after its start at 4.0Hz . The actual maximum
operating frequency is limited by the upper limit of frequency.
For the related parameters refer to CD031, CD140 and CD141.
CD042 Stopping Frequency
Set Range: 0.10—10.00 Hz Unit: 0.01Hz Factory Setting: 0.50
When stopping the inverter will decrease its f requency to the stopping
frequency and then stop running or start DC braking to stop.
If CD142 is set to 0, DC braking is invalid at stop and the inverter will stop
running.
If CD142 is set for valid, the inverter will stop by DC braking.
For the related parameters refer to CD032, CD140 and CD142.
CD043 Auto Torque Compensation
Set Range: 0.0—10.0 % Unit: 0.1% Factory Setting: 2.0
This parameter can be
set for the auto output
of e x t r a vol t a ge
when the inverter is
running to achieve
higher torque, which
can compensate for
the under-torque at
lower f requency. The
torque compensation should not be too big and it should be set slowly from low
to high according to the actual situation.
Insufficient compensation will result in the under-torque of the motor at lower
frequency. And over compensation will lead to too bigger torque, which will
produce a shock to the machine and even result in a trip of the inverter under
serious situation.
