22 Group AC drive data and configuration

Depend on drives power
≤7.5kW:
11kW～45kW: 1kHz～8kHz
≥55kw:
The carrier frequency can be reduced when it
came like following phenomenon:
1 The leakage current generated by the
inverter is large
2 The interference generated by the inverter
has an impact on peripheral devices
3 Long wiring distance between inverter and
motor
The carrier frequency can be increased
whenwhen it came like following
phenomenon:
1 The electromagnetic noise generated by the
motor is large
Unit'digit：adjustment as per Rotation
0:No；1:Yes
Ten'digit：adjustment as per Temperature
0 no；1：yes
1.0kHz～15.0kHz
1.0kHz～15.0kHz
0.00Hz～600.00HzWhen the carrier
frequency is adjusted according to the output
frequency, the carrier frequency set by
P22.02 is used when the output frequency is
lower than this set value.
0.00Hz～600.00Hz When the carrier
frequency is adjusted according to the output
frequency, the carrier frequency set by
P22.03 is used when the output frequency is
higher than this set value.
0：SVPWM
It is normally used
1：SVPWM+DPWM
Using this modulation method can reduce the
switching loss of the inverter and reduce the
probability of overheating alarm of the
inverter; however, the electromagnetic noise
of the motor in the medium speed section will
be too large.
2：PWM at random
The electromagnetic noise generated by the
motor is white noise, not a sharp squeak.
3：SPWM
1kHz～12.0kHz
1kHz～4kHz
