3.1 Setting basic parameters
3.1.1 Brief description of parameters
Parameters are the values used to configure inverter operation. These are notated as "Pr.". The type and num-
ber of parameters available differ depending on inverter model.
For simple variable-speed operation of the inverter, the initial values of the parameters may be used as they are.
Configure the necessary parameters in accordance with loads and operational specifications. Parameters can
be configured, changed, and confirmed from the operation panel.
3.1.2 Typical parameters
Pr. Name Unit Initial value Range Application
0 Torque boost 0.1%
6%/4%/
3%/2% *
0 to 30%
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. (0.75K or lower/1.5K to 3.7K/5.5K,
7.5K/11K, 15K)
1 Upper-limit frequency 0.01Hz 120Hz 0 to 120Hz Configure this to set a limit on the maximum
output frequency.
2 Lower-limit frequency 0.01Hz 0Hz 0 to 120Hz Configure this to set a limit on the minimum out-
put frequency.
3 Base frequency 0.01Hz 60Hz 0 to 400Hz
Configure this when the rate frequency of the
motor is not 60Hz.
Check the motor rating plate.
4
Multi-speed setting
(high speed)
0.01Hz 60Hz 0 to 400Hz
Configure this to change the preset speed
parameter with a terminal.
5
Multi-speed setting
(middle speed)
0.01Hz 30Hz 0 to 400Hz
6
Multi-speed setting
(low speed)
0.01Hz 10Hz 0 to 400Hz
7 Acceleration time 0.1 s 5s/10s/15s * 0 to 3600 s Acceleration/deceleration time can be set.
* Initial values differ according to the inverter
capacity.
(3.7K or lower/5.5K, 7.5K/11K, 15K)
8 Deceleration time 0.1 s 5s/10s/15s * 0 to 3600 s

Pr.CL Parameter clear 1 0 0, 1
Setting "1" returns all parameters except calibra-
tion parameters to the initial values.
ALLC All parameter clear 1 0 0, 1
Setting "1" returns all parameters to the initial
values.
The following table lists the most commonly used parameters.
● Parameters are configured with initial values so that inverters can operate without specific configuration.
Parameters can be configured in accordance with the motors and devices used in your environment.
