Introduction
3~ 380V…460V, +10% - 15%, 400 - 1100kW

Varispeed-G5HP 800kW (closed)
The Varispeed-G5HP is the best solution for systems in the high power segment. It achieves optimum control over a wide range of applications for variable torque such as fans and pumps and constant torque applications such as extruders and printing machines.

The advantage of the Varispeed-G5HP lies in significant functions such as variable speed range of 1:1000 torque limit (in close loop mode) with maximum cost performance.

Equipped with four control modes

• V/f Control : For control of multiple motors

Applications

Optimum performance for your application
The optimum control can be obtained by selecting characteristics for variable torque (VT) or constant torque (CT).

Torque control to protect machines
The precise torque limit function allows accurate control of the output torque, protecting your machines from sudden load fluctuations.

High-speed response
In Open-loop vector control: the speed response is 5Hz. In closed loop vector control (with PG feedback) the Speed response 40 Hz. Our unique high-speed current vector control enables your machine to respond more rapidly to speed-reference changes. The speed remains constant even if the load fluctuates.

High starting torque
With close loop vector control, a high-torque operation of 150% or more is possible from zero speed. With open-loop vector control, a high-torque operation of 150% at 0.5 Hz is possible from a low speed of 1/100 when CT is selected.

Hardware

Global standards

• Open- loop current vector : High-performance drive without speed detector (no need of PG wiring)
• V/f Control with PG feedback : Speed control using the machine’s axis speed feedback
• Open Loop Vector Control : High precision drive using PG feedback. High precision positioning, zero speed and torque control
• High starting torque: 150% at 1Hz (open loop); 150% at 0Hz (closed loop)
• Clear operator interface with alpha numeric display
• Options available for most communication interface protocols
• Reactors, main switch, wiring, power buses, connectors and cooling fans are sourced locally and the drives are assembled to order
• Extruder
• Mills
• Fans & Pumps
• Conveyors
• Torque Control : The motor torque can be controlled freely using external references. This function is effective for winding and rewinding motions of winders.
• Droop Control : This function arbitrarily sets the slip of the motor. This function is effective for material handling machines such as cranes and conveyors.
• Zero-servo Control : No matter if an external force is applied or an offset is set for an analogue reference input, this function stops a motor electrically and forcibly when the frequency (speed) reference drops to the zero-speed level.
• Rotational Auto Tuning : (open-loop vector control, closed loop vector control) Use this auto tuning for the applications where high-starting torque and high speed control accuracy are required.
• Various I/O interfaces :The VarispeedG5HP supports various I/O interfaces with 8 (conventionally 7) digital inputs and 3 analogue reference input terminals (conventionally 2). Analog reference card (AI-14U and AI-14B) and digital reference card (DI-08 and DI-16H2) are also available. Input terminal logic can switch between sink (0V common) or source (+24V common). An external +24V power supply is also available for selecting the signal input.
• Supporting global field networks : All models are fully compliant with RS-422/485 (MEMOBUS/Modbus protocol) standards. The networks are available by using communications option cards. Now you can connect to hosts and PLC, implement centralized management of production equipment and reduce wiring easily.
• Countermeasures to minimize harmonics current : All Models are equipped with a built-in DC reactor to minimize harmonics current. They also provide an optional 12-pulse input to prevent current distortion.
• CE marking
