Simple mode parameters
7 PARAMETERS
Simple variable-speed operation can be performed with the inverter in the initial settings. Set the required parameters
according to the load and operating conditions. Use the operation panel to set or change a parameter. (Refer to Chapter 4
of the Instruction Manual (Applied) for the detailed description of parameters.
7.1 Simple mode parameters
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. (

Set when you want to increase a starting torque or when the
motor with a load will not rotate, resulting in an alarm [OL] and a
trip [OC1].
∗ Initial values differ according to the inverter capacity.

1 Maximum frequency 0.01Hz 120Hz 0 to 120Hz Set when the maximum output frequency need to be limited.
2 Minimum frequency 0.01Hz 0Hz 0 to 120Hz Set when the minimum output frequency need to be limited.
3 Base frequency 0.01Hz 60Hz 0 to 400Hz
Set when the rated motor frequency is 50Hz.
Check the motor rating plate.
