YASKAWA Varispeed f7 User Manual

5-84
Note Attach a Momentary Power Interruption Compensation Unit if compensation for power interruptions of up to 2.0 seconds is required for 200 V Class
Inverters with outputs of 0.4 to 11 kW.
* 1. The factory settings when VT is selected are given.
When CT is selected, the factory settings are as follows for Inverters of any capacity:
Carrier frequency selection: 1 (2.0 kHz)
Carrier frequency selection upper limit: 2.5 kHz
* 2. The setting of C6-02 changes the carrier frequency selection as follows:
0: Low-noise PWM, 1: 2.0 kHz, 2: 5.0 kHz, 3: 8.0 kHz, 4: 10.0 kHz, 5: 12.5 kHz, 6: 15.0 kHz
* 3. 95 for Inverter SPEC Type A.
* 4. When setting the carrier frequency of 200 V Class Inverters of 30 kW or more to a value larger than the factory setting, reduce the value of the Inverter
rated output current.
