    solar pump inverter is really in very good quality and we also prepared some promotional products for exhibition. We are going to make new orders soon. Last year there was only one local agent and this year, there are more than 8. Some of them only sell Veikong!

    It’s very good! LCD options make it much easier to use. That’s the strong point, easy of use. And robust. Great PC software.

    VFD500 output frequency is stable when the others are fluctuating. Also output current is less than others, that’s why output frequency is higher too which can save more energy.

P23.00 DC Bus voltage control option

Ø Unit’digit :Overvoltage stall control
0:overvoltage stall disabled
1:overvoltage stall enabled
2:overvoltage stall enabled self-adjustable

Ø The over-voltage stall function limits the amount of power generated by the motor by extending the deceleration time or even increasing the speed, avoiding over-voltage on the DC side and reporting over-voltage faults
Ten’unit:Undervoltage stall control
0:undervoltage stall disabled
1:Undervoltage stall(decelerate to zero speed and be in standby mode,after power restoring ,it will run again automatically)
2: Undervoltage stall deceleration(decelerate to zero and stop)

Ø The undervoltage stall function reduces the motor power consumption or reduces the power consumption of the motor or turns it into a power generation operation to avoid the undervoltage fault on the DC side.

Ø The undervoltage stall function is used when the input power supply quality is poor (the power supply voltage fluctuates downward or the sporadic short power is suspended), and it is necessary to keep the inverter running as much as possible.
