General specification for VC680 CNC VFD variable frequency controller




Rated frequency and voltage

Three-phase: 380~440V, 50/60Hz;

three-phase/single-phase: 220~240V, 50/60Hz

Operating range of voltage and frequency

Voltage: 20%; frequency: 5%



0~input voltage



Over-load capacity

1min at 150% of the rated current and 1s at 200% of the rated current

Main control properties

Control mode

Vector control

Range of speed regulation


Torque characteristics

High torque output, starting torque can reach 150% at 1Hz.

Frequency accuracy

Digital setting: 0.01%; analog setting: 0.2%

Frequency resolution

Digital setting: 0.01Hz; analog setting: 0.1% of the max. frequency

Start modes

3 modes: start from start frequency, start after brake and start after rotating speed tracking


deceleration modes

3 modes: straight line mode, settable S-curve mode (independently adjustable proportions of start and end sections of S-curve) and automatic acceleration and deceleration mode

Stop modes

3 modes: decelerated stop, decelerated stop+DC braking and free stop

DC braking

Start frequency of braking: 0~60.00Hz, or determined by external input terminals.

Braking time: 0.0~60.0s, or determined by external input terminals.

Braking current: 0.0~100.0% of the rated current of frequency converters

Dynamic  brake

Adjustable max.braking torque.


Range of jog frequency: 0.00~upper limiting frequency; jog acceleration/deceleration time: 0.0~6553.5s; jog interval can be set.

Automatic voltage regulation

When input power grid voltage fluctuates, stability of output voltage can be kept automatically.

Fast current limit

Fast current restraining ability prevents frequent over-current trips and realize the characteristics of excavator (output torque is kept for locked-rotor of motors).

Automatic carrier regulation

Carrier frequency can be automatically regulated to optimize system state in accordance with load characteristics.
