the motor is bigger. In reserve, the lower the water yield is, the more stable the motor
frequency is.
5.4.2 Special settings for single phase motors
a) When the single phase motor is in bad running performance, the user can adjust P04 VF
curve settings: set P04.00=1 and set P04.03P04.08 to appropriate values according to
commissioning conditions; increase the voltage if the motor cannot start and decrease the
voltage if the current is high.
b) When the light is normal and the system starts slowly, increase P15.28 initial voltage
differential value appropriately.
c) For single phase motors with two-phase control (capacitor-removing):
The maximum voltage needs to be less than 1/1.6 of the bus voltage. It is recommended to
set the rated voltage P02.04 less than 200V, or limit the maximum voltage output by multi-dot
V/F curve.
Observe the currents of the windings through P17.38 and P17.39, the switched current is
the combination current of the two windings. The impedances of the windings are different, so
the currents are different at the same voltage output.
P04.35 can be used to change the output currents of the main and secondary windings. It is
recommended that qualified engineers perform adjustment since the voltage adjustment is
associated with motor design parameters. Otherwise, the motor performance may be
impacted.
