●
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.
