●

The motor torque in the low frequency area

can be adjusted according to the load.

Pr.7

Acceleration/deceleration time

Pr.8

●

For the acceleration time, set the time to reach

the acceleration/deceleration reference frequency
Pr. 20 (default value: 60Hz) from 0Hz,
and for the deceleration time, set the time to reach
0Hz from Pr. 20 (default value: 60Hz).

Electronic thermal O/L relay

Pr.9

●

The setting value to protect the motor from

overheating can be set as a current value.
Normally, the motor rated current is set for 50Hz.

●

When 0A is set, the motor protective function

will not activate. (The inverter output transistor's
protective function will activate.)

●

When connecting multiple motors, set an external

thermal relay for each motor.

Extended function display selection

Pr.30

●

Set this to display and set the extended function parameters.

Operation mode selection

Pr.79

●

The inverter operation modes include operation

with external signal and operation with the PU
(setting dial, touch keys). The mode can be fixed
to one mode, or two modes can be used together.

Pr.1

Maximum/minimum frequency

Pr.2

Base frequency

Pr.3

●

The upper limit and lower limit of the output

frequency is clamped.

●

Set the base frequency (reference frequency for motor

rated torque) between 0 and 120Hz according to the motor.

Pr.4 Pr.5

Multi-speed setting

Pr.6

●

Various speeds (RH, RM, RL) can be selected

just by changing the contact signal from an
external source.

●

Each speed (frequency) can be set

between 0 and 120Hz while the inverter is running.
