(1) If F_12 = 7 up to 10, the inverter must operate with low load.
Although an IGBT TYPE inverter 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.
Fn_13: Torque compensation gain = 0 up to 10 %
To enhance Inverter 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 Fn_13 = 0, the torque boost function is disabled.
