Maximum
frequency
25.0 to 400.0 Hz variable
Base frequency
25.0 to 400.0 Hz variable
Starting frequency
0.1 to 60.0 Hz variable
Carrier frequency
0.75 to 16 kHz variable
Note:
To protect the inverter, when the carrier frequency is 6 kHz or
more, the carrier frequency automatically lowers depending upon
the ambient temperature or output current states. (The automatic
lowering function can be disabled.)

Voltage/frequency
characteristics
200 V
series
• Possible to set output voltage at base frequency and
at maximum output frequency (80 to 240 V).
• The AVR control
*1
can be turned ON or OFF.
• Non-linear V/f
*1
setting (2 points): Free voltage (0 to
240 V) and frequency (0 to 400 Hz) can be set.
400 V
series
• Possible to set output voltage at base frequency and
at maximum output frequency (160 to 500 V).
• The AVR control
*1
can be turned ON or OFF.
• Non-linear V/f
*1
setting (2 points): Free voltage (0 to
500 V) and frequency (0 to 400 Hz) can be set.
Torque boost
*1
• Auto torque boost (For constant torque load)
• Manual torque boost: Torque boost value can be set between 0.0
and 20.0%.
• Select application load with the function code. (For variable torque
load or constant torque load)
Starting torque

• 150% or more (Running at 1 Hz, with slip compensation and auto
torque boost active)
Start/stop operation
Keypad: Start and stop with RUN and STOP keys (standard keypad/
optional remote keypad)
External signals (digital inputs): Run forward and stop command,
Run reverse and stop command, coast-to-stop command, etc.
Link operation: Operation through RS-485 (built-in as standard)
