5 Commissioning guidelines
Disconnect all power supplies applied to the VFD before the terminal
wiring and wait for at least the designated time after disconnecting the
power supply.
High voltage is present inside the VFD during running. Do not carry out
any operation except for the keypad setting.
The VFD automatically runs once power on. If parameters need to be set,
follow the guidelines in this chapter.
5.1 Inspection before operation
Before powering on the VFD, ensure that:
a) The VFD is grounded reliably.
b) The wiring is correct and reliable.
c) The AC/DC breaker is selected correctly.
d) The PV input voltage is in the allowed range of the VFD.
e) The type, voltage, and power of the motor match those of the VFD.
5.2 Trial run
Close the DC breaker. The VFD automatically runs with a delay of 10 seconds. Check the
water yield of the pump. If the water yield is normal, the trial run is successful. If the water yield
is under the normal value, exchange any two motor cables, connect the cables, and perform
trial run again.
5.3 Parameter settings
The VFD automatically runs by default once being powered on. If you want to set parameters,
press QUICK/JOG within 10 seconds since the VFD power-on to switch to the keypad control
mode (LOCAL/REMOT is off) and then set parameters. If the running indicator is already on
after the VFD is powered on, press STOP/RST to enter the parameter setting mode. After
parameter setting, turn off and then turn on the power switch. The VFD runs again.
5.4 Advanced settings
Note:
The default settings of the VFD for the water pump can apply to most conditions and the
advanced settings are not required in most cases.
5.4.1 PI adjustment to the water yield
If the user requires large or low water yield, it is necessary to adjust PI (P15.06–P15.10)
properly. The bigger PI parameters, the stronger the effect is, but the frequency fluctuation of
