Detailed Parameter Description
No. Parameter
name
Description
Starting frequency
Used to specify the inverter’s starting output frequency.
∗
Increasing [Starting frequency] enhances the torque at start-up.
However, this condition is almost direct start, and it is not suitable for
shockless start. Furthermore, the inverter may trip depending on the load
condition.
Automatic voltage
adjustment
reference voltage
Select the motor’s rated voltage for automatic voltage adjustment.
Automatic voltage
adjustment
selection
Used to suppress fluctuations in output voltage by correcting an output
voltage relative to fluctuations in input power supply voltage.
However, a voltage higher than the power supply voltage cannot be output.
Parameter lock
Allows the optional locking of parameters.
■
Parameters are not locked
●
All parameters are locked
●
Parameters that require no setting are locked.
•
Selecting
deactivates DATA SET , MODE ,
△
and
▽
switches, inhibiting parameter setting procedure.
( RUN and STOP switches remain active.)
•
Selecting
allows the parameters selected by means of
parameter [
] to be set.
Copy parameter
For copying procedure, refer to [Parameter copying method].
■
Disables parameter copy.
●
Loads a parameter onto the operation panel.
●
Saves a parameter into the inverter.
●
Panel data initialization
For details, refer to Copying parameter .
Motor rated current Used to specify the motor’s rated current for slip frequency vector control.
∗
1
Motor no-load
current
Used to specify the motor’s no-load current for slip frequency vector control.
∗
1
Motor primary
resistance
Used to specify the motor’s primary resistance for slip frequency vector
control.
∗
1
Slip correction gain Used to adjust the slip correction gain for slip frequency vector control.
Slip correction
response time
Used to specify the slip correction response time for slip frequency vector
control.
∗
1 Because a motor constant is required for slip frequency vector control, the standard constant for our
motors has been specified as the default setting. To operate other manufacturer’s motor, specify
the constant of the motor used.
