3.2 Before operation

3.2.1

Simple mode parameter list

For simple variable-speed operation of the inverter, the initial setting of the parameters may be used as they are. Set
the necessary parameters to meet the load and operational specifications. Parameter setting, change and check can
be made from the operation panel (FR-DU07). For details of parameters, refer to Chapter 4 of
Manual (Applied).
POINT
Only simple mode parameter can be displayed using Pr.160 User group read selection. (All parameters are displayed
with the initial setting.) Set Pr. 160 User group read selection as required. (Refer to page 53 for parameter change.)

Applications
Set to increase a starting torque or when the
motor with a load will not rotate, resulting in an
alarm [OL] and a trip [OC1]
*1
The initial value differs according to the inverter
capacity. (0.4K, 0.75K/1.5K to 3.7K/5.5K, 7.5K/
11K to 55K/75K or higher)
Set when the maximum output frequency need
to be limited.
*2
The initial value differs according to the inverter
capacity. (55K or lower/75K or higher)
Set when the minimum output frequency need
to be limited.
Set when the rated motor frequency is 50Hz.
Check the motor rating plate.
Set when changing the preset speed in the
parameter with a terminal.
Acceleration/deceleration time can be set.
*3
The initial value differs according to the inverter
capacity. (7.5K or lower/11K or higher)
Protect the motor from overheat by the inverter.
Set the rated motor current.
*4

Select the operation command location and
frequency command location.
Frequency for the maximum value of the
potentiometer (5V initial value) can be changed.
Frequency for the maximum current input
(20mA initial value) can be changed.
Parameter which can be read from the
operation panel and parameter unit can be
restricted.
