V/f curve | V / f curve type: straight line, multipoint, power function, V / f separation; Torque boost support: Automatic torque boost (factory setting), manual torque boost | |
Frequency giving ramp | Support linear and S curve acceleration and deceleration; 4 groups of acceleration and deceleration time, setting range 0.00s ~ 60000s | |
DC bus voltage control | Overvoltage stall control: limit the power generation of the motor by adjusting the output frequency to avoid skipping the voltage fault;
Undervoltage stall control: control the power consumption of the motor by adjusting the output frequency to avoid yaw failure
VdcMax Control: Limit the amount of power generated by the motor by adjusting the output frequency to avoid over-voltage trip; VdcMin control: Control the power consumption of the motor by adjusting the output frequency, to avoid jump undervoltage fault | |
Carrier frequency | 1kHz～12kHz(Varies depending on the type) | |
Startup method | Direct start (can be superimposed DC brake); speed tracking start | |
Stop method | Deceleration stop (can be superimposed DC braking); free to stop | |

Product series instruction:
VEIKONG VFD application:
VEIKONG VFD replace famous brands
R&D test: test the hardware and software performance, to make the design more optimization, makes sure the products have excellent
performance before production;
Board test: test the performance of every board in our products, to reduce product defective rate;
IQC: take strict quality inspection for every income components, to ensure every income components are qualified.
Aging test: make the solar pump VFDs at run status, put them in the aging test house at 50°C for 48 hours, to remove every unqualified products.
Load test: the last and the most important test, add different load to the solar pump VFDs, test their input and output value, to check their
working performance. unqualified products will be removed from the team.
By applying such strict testing process, VEIKONG ensures every outgoing solar pump VFD has excellent quality.
