Description:

HV1000-H2 is specialized for high frequency inverter applications. The frequency could be up to 2000Hz.

 HV1000 series of VFD has equal quality and feature with Emerson EV3000 but much more cost-effective, much better feature than Emerson commander SK. It satisfies high performance requirements by using a unique control method to achieve high torque, high accuracy and wide speed-adjusting range. Its anti-tripping function and capabilities of adapting severe power network, temperature, humidity, and dusty environment exceeds those of similar products made by other companies, which improves the products reliability noticeably.

Features of HV1000 frequency inverter

Precise self-learning of motor parameter

• Precise self-learning of motor parameter
• Static mode: Stator/rotor time constant
• Dynamic mode: Magnetic flux parameter
• The best dynamic control

Optimizing of motor noise and heat

• Unique modulation technology, decreasing current harmonics
• Frequency spectrum balance technology, adjusting motor tone
• Decrease common-mode voltage, reducing leak current
• Carrier wave dynamic adjusting, reducing the temperature
• Reducing switching frequency when high-frequency, decreasing the module heat

Optimized Over-modulation technology

• Applications needing high frequency and load, with lower Voltage of Power supply
• Increase efficiency of DC-Bus voltage, increase the output voltage
• Provide the enough torque output
• Decrease output current, reduce the heat

Unique current limit technology

• Load current control in real time, automatic current amplitude limit, strong over-load ability
• Instantaneous value / effective value controlled together

Speed tracking function with hardware

• Avoid the speed tracking lost with software, 100% successful
• Track the motor speed and direction smoothly and reliably

Instantaneous stop & non-stop

• Instantaneous power off, keep the continuous running
• Keep the DC-Bus voltage according to  electricity generating from the load
• Suitable for applications that need continuous running, e.g. chemical fiber, chemical industry

Preset Length control

• Textile / Cable and other similar industry
• Feed back the encoder signal through high-speed pulse interface
• Automatic length calculation, stop the machine when reach the preset length

0-frequency returning difference and dormancy

• To avoid the damage when fan/pump load starts frequently in low speed, even with PI closed-loop control
• Water-supply system need dormant running in night
• Variable-Frequency air conditioner or constant pressure water supply
