F_12: Carrier Frequency = 1 ~ 10
F_12 Carrier Frequency F_12 Carrier Frequency F_12 Carrier Frequency
14 kHz 5 8 kHz 9 15 kHz*1
2 5 kHz 6 10 kHz*1 10 16 kHz*1
36 kHz 7 12 kHz*1
4 7.2 KHz 8 14.4 kHz*1
NOTE:
*1: Available for CPU version V1.9 and above.
2: If F_12 = 7~10, the inverter must operate with light loads.
Although an IGBT TYPE AC drive can provide a low audible noise level during its operation, it is possible that the switching of the
high carrier frequency may interfere with external electronic components (or other controllers) or even cause vibration in the
motor. Adjusting the carrier frequency can usually correct this problem.
F_13: Torque Compensation Gain = 0 ~ 10%
To enhance AC drive output torque patterns according to the B, C voltage points on the V/F pattern (refer to F_05 description)
and the (F_13) for this feature.
NOTE: When F_13 = 0, the torque boost function is disabled.
