8.3 Common Specifications
Item Explanation
Maximum frequency
25 to 500 Hz (120 Hz for inverters in MD/LD mode)
(120 Hz under vector control without speed sensor)
(200 Hz under V/f control with speed sensor or vector control with speed sensor)
Base frequency 25 to 500 Hz (in conjunction with the maximum frequency)
Starting frequency 0.1 to 60.0 Hz (0.0 Hz under vector control with/without speed sensor)
Setting range
Carrier frequency
• 0.75 to 16 kHz (HD mode: 0.4 to 55 kW, LD mode: 5.5 to 18.5 kW)
• 0.75 to 10 kHz (HD mode: 75 to 400 kW, LD mode: 22 to 55 kW)
• 0.75 to 6 kHz (HD mode: 500 and 630 kW, LD mode: 75 to 500 kW)
• 0.75 to 4 kHz (LD mode: 630 kW)
• 0.75 to 2 kHz (MD mode: 90 to 400 kW)
Note: The carrier frequency may automatically drop depending upon the surrounding temperature
or output current to protect the inverter. (The automatic drop function can be disabled.)
