motor
V0, V1, V2, V3 and f0, f1, f2 and f3 in the figure are voltage value and frequency value set by
parameters P31.01~P31.08.
2: 1.2nd power
3: 1.4th power
4: 1.6th power
5: 1.8th power
6: 2.0th power
Parameter values 2~6 apply to torque-dropped loads such as fans and water pumps. See Fig.
6-42.
Rated voltage of motor
7: V/f separated pattern 1
Output frequency and output voltage can be set separately. Frequency is set by the method
as stated in Group 10. Output voltage is set by P31.18. See P31.18 for details. This mode
applies to variable-frequency power supply or torque motor control etc.
