3.3 Parameter Checking and Setting
3.3 Parameter Checking and Setting
The inverter is designed to perform simple variable-speed operation with the factory settings of the
parameters. Set the necessary parameters according to the load and operation specifications. Use the
operation panel (FR-DU04) to set, charge and confirm the parameter values. For full information on the
parameters, refer to "CHAPTER 4 PARAMETERS"(Page 62).
3.3.1 Parameter checking
Pr. 160 "user group read selection" is factory-set to display only the simple mode parameters among the
parameters. Set the following parameters as required.

Name
Used to compensate for a voltage drop in the low frequency range to
improve motor torque reduction in the low speed range.
Used to set the upper and lower limits of the output frequency.
Used to match the inverter outputs (voltage, frequency) to the motor
rating.
Set these parameters when using the terminals to change the
running speeds preset in the parameters.
Used to set the acceleration and deceleration times.
Used to set the current value of the electronic overcurrent protection
to protect the motor from overheat.
Used to adjust the stopping accuracy according to the load.
Used to select the optimum output characteristic that matches the
application and load characteristics.
Used to set the base voltage (e.g. motor's rated voltage).
Used to choose the monitoring and output signals.
Used to set the frequency and current values, which are referenced,
for the level meter.
Used to perform automatic restart operation after instantaneous
power failure or commercial power supply-inverter switchover.
