Note Attach a Momentary Power Interruption Compensation Unit if compensation for power interruptions of up to 2.0 seconds is required for 208-240Vac
Drives with outputs of 0.4 to 7.5 kW.
* 1. The initial settings for C6-02 are as follows: 0: Low noise PWM, 1: 2.0 kHz, 2: 5.0 kHz, 3: 8.0 kHz, 4: 10 kHz, 5: 12.5 kHz, and 6: 15 kHz. If the carrier
frequency is set higher than the factory setting for Drives with outputs of 5.5 kW or more, the Drive rated current will need to be reduced.
* 2. The initial settings for C6-11 are as follows: 1: 2.0 kHz, 2: 4.0 kHz, 3: 6.0 kHz, 4: 8.0 kHz.
