8.3 Common Specifications
Item Explanation
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
Setting range
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.) *1
Output frequency accuracy
(Stability)

and frequency (0 to 400 Hz) can be set.
Voltage/frequency
characteristics
400 V
class 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.

and stop command, coast-to-stop command, etc.
Control
Start/stop operation
Link operation: Operation through RS-485 (built-in as standard)
*1 Available only for induction motor drive.
*2 Not supported by the first version.
