GK500 Mini AC Drives (V/F control)
- GK500 series adopt book-type frames to save mounting space
- Small in Size
- Powerful in Performance
- Hot pluggable display with inbuilt potentiometer
- Optimized design on heat dissipation
- Wide range of applications
Promoted V/Hz
Promoted V/Hz control technique make the start torque reach 180% cf the rated at 0.5Hz
Strong Adaptability
Derating is not required for GK500 at ambient temperature up to 50 C
Multi-step Speed
8-step speed is supported, two of which accept various frequency references.
GK620 General Purpose AC Drives (V/F control, SVC1, SVC2)
- GK620 drives support the auto-tune of two motors.
- GK620 drives can output up to 180% of the Rated torque at 0.5Hz, V/f mode and SVC1 mode; can output 180% at 0.25Hz, SVC2 mode.
- 150% current can be provided for 1 minute, 180% for 10 seconds, and 200% for 0.5 second.
- At rated condition, the efficiency of the drives 7.5kW and below is higher than 93%, 11kW till 45kW is no less than 95%, while 55kW and above is higher than 98%.
Highlights
- More Lighter, More Powerful
- Multifunctional and Versatile
- Intelligent heat dissipation
- Hot pluggable and detachable control panel
- Abundant hot-plugged options
- Three control modes
- Flying start supported
- Quick dynamic response
- Cycle-by-Cycle current limit
- Short dead time between forward and reverse
- Wide range of application
Big start torque
GK620 drives can output up to 180% of rated torque at 0.25Hz.
Overload Capability
In standard conditions, GK620VFDs can withstand 200% rated current for 0.5second.
High Efficiency
At rated input voltage & rated load condition, the efficiency of GK620 drives are up to 98%
GK820 High Performance AC Drives (V/F control, SVC1, SVC2, VC control)
- GK820 VFDs support auto-tune of two motors.
- GK820 AC drives can output up to 180% of the Rated torque at 0.5Hz under V/f mode and SVC1 mode, output up to 180% at 0.25Hz, SVC2 mode, while at VC mode up to 200% at 0Hz.
- Speed control and torque control can be switched via terminal or programmed by parameter.
- GK820 drives are configured with electronic gear, quite convenient for the applications when the encoder is not easily to be mounted at the motor shaft. The shaft that the encoder is mounted at is requested to have fixed spinning speed ratio with motor shaft.
Highlights
- More lighter, More Powerful
- More Beyond Inheritance
- One for all
- Hot pluggable and detachable control panel
- Abundant options
- Four control modes ?V/F control, SVC1, SVC2, VC control?
- Four kinds of position control
- Flying start support
- Cycle-by-Cycle current limit

Supreme start torque
GK820 can output 200% of the rated output torque at 0 Hz under VC control mode2
Torque Control
GK820 supports torque control in accuracy of ±5%, while response time is less than 5ms3
Flexible Electronic Gear
VC control still can be performed even the encoder is not easily to be mounted4
GK510 dedicated drives are tailored for textile industry
