BPD series PV pumping inverter Commissioning guide

(2) Set the motor type through P02.00: 0 indicates 3PH motor and 1 indicates
1PH motor. You need to set P04.34 to 0x01 when the capacitor-removed 1PH
motor is drived in the 2PH control mode.
(3) Set the name plate of the motor, including P02.01, P02.02, P02.03, P02.04
and P02.05 (the maximum setting of P02.04 is 200V for a 1PH motor whose
capacitor is removed).
3. Set P15.29=0.
4. Detect water yield for water pumps
Click "Run" key, observe the running frequency and water yield. If the running
frequency or water yield is low at normal light, the motor wires may be reversed, it
is necessary to set P00.13=1 or exchange the wiring of the motor. The operation
direction of 1PH motor whose capacitor is removed can only be changed by
function code.
5. Set the operation mode
After the water yield is normal and the system runs stably, set the operation mode.
(1) Automatic operation: set P00.01=1, P05.01=1;
(2) Manual operation: set P00.01=1, P05.01=0 and P05.04=1, and select S4 as
the start and stop control terminal, as shown in the preceding wiring diagram.
The system can run only after S4 is switched on. For models of 380V, you can
press the "RUN/STOP" button on the enclosure to run the inverter,
6.4 Advanced settings
Note: The default setting of the inverter for water pump can apply to most conditions
and the advanced setting is unnecessary.
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 the motor is bigger; in reserve, the lower the water yield
is, the more stable the motor frequency is.
2. Commissioning of MPPT speed tracking
P15.23 and P15.24 is the minimum and maximum voltage of the power tracking in
MPPT mode. If the voltage range is smaller, the faster the tracking is. But the bus
voltage in normal operation needs to be in the range; otherwise the maximum
power cannot be tracked. Generally:
(1) Model of BPD0K7TN(AC): P15.23=80.0 (Min. reference voltage),
P15.24=400.0 (Max. reference voltage)
(2) Models of BPD1K5–004TN(AC): P15.23=100.0 (Min. reference voltage),
