Motor Controls: AC Varable Speed Drives

GS1 Series Mini-Drives

The GS1 series of AC drives are our most affordable and compact inverters, offering V/Hz control with advanced application features. These drives can be configured using the built-in digital keypad (which also allows you to set the drive speed, start and stop, and monitor specific parameters) or with the standard RS485 serial communications port. Standard GS1 features include one analog input, four programmable digital inputs and one programmable normally open relay output.


GS2 Series Micro-Drives

The GS2 series of AC drives offers all of the features of our GS1 drives plus dynamic braking, PID and a removable keypad. The drive can be configured using the built-in digital keypad or with the standard RS485 serial communications port. The standard keypad allows you to configure the drive, set the speed, start and stop the drive, and monitor specific parameters during operation. Each GS2 AC drive features one analog and six programmable digital inputs, and one analog and two programmable relay outputs.


DURApulse AC Drives (GS3 Series)

DURApulse-GS3_AC_drives The DURApulse series of sensorless vector drives. Built on the simplicity and flexibility of the GS1 and GS2 series drives, DURApulse drives are available in 1 to 100 Hp models and offer sensorless vector and closed loop control, autotuning, 175% starting torque, and 150% rate current for one minute.

The DURApulse series of AC drives offers all of the features of our GS2 series drives, including dynamic braking, PID, removeable keypad and RS485 MODBUS communication. The DURApulse drives also offer sensorless vector control with the option of encoder feedback for enhanced speed control.

The standard smart keypad (a.k.a. HIM or Human Interface Module) is designed with defaults for North American customers and allows you to configure the drive, set the speed, start and stop the drive, and monitor critical parameters for your application. In addition, this keypad has internal memory that allows four complete programs to be stored and transferred to any DURApulse drive. The DURApulse series offers three analog inputs, eleven digital inputs, and one SPDT relay output.

Open serial communications are available with a standard RS485 MODBUS serial interface, which offers communications up to 38.4 K. An Ethernet option, combined with AutoamtionDirect's, KEPDirect EBC I/O Server can be used to connect the drives to any OPC client.

DURApulse drives are UL and CE listed, and come with a two-year replacement warranty.

Accessory Items - AC Drives

A variety of accessory items are available to support both the GS series and Hitachi series AC drives. If you need to protect your drive from spikes, surges or short circuits, we offer a variety of line reactors. Other items include: input fuse kits, spare input fuses, braking options, EMI/ RFI filters, communications options and drive configuration devices, software and cables. Other spare parts are also available.

  • Line reactors - Protect your drive from spikes, surges or short circuits.

  • Input fuse kits - For circuit protection. Kits consist of one fuse block and fuses sized to match each drive. Replacement fuses are also available.

  • Braking options - An optional braking resistor may be required for applications that require rapid deceleration or high inertia loads. Used to increase the control torque of the inverter, for frequently repeated ON-OFF cycles of the inverter, or for decelerating a load with large inertia

  • Keypads and Cables - Spare keypads, keypad cables and other cables are available for the GS2 drives

  • Configuration Software - GSOFT, the configuration software for the GS Series drives, allows a personal computer to be connected to either the GS1 or GS2 series drives. The Hitachi Drive Manager Software Suite (DOP-PRO) is a collection of programming software that covers the full range of our Hitachi drives. The DOP Plus software is an emulation program based on Hitachi handheld programming devices. For SJ100 drives, the QuickStart program enables remote programming from your PC with a simple menu-driven Windows-based system. The SRW-OEX Simulator is an online programming tool for the SJ300 Series drives.
  • Configuration Devices - There are several choices when deciding how to configure, control, or monitor your Hitachi SJ100 or SJ300 drive, including a built-in digital keypad, remote display with stop button, or digital remote operator with serial communications.

  • Communication Options - Ethernet and RS485 communication capabilities are available for the GS drives. There is an Ethernet drive module available for Hitachi SJ100 series drives. The SJ-FB encoder feedback board improves the SJ300’s speed regulation and torque response.

  • EMI/ RFI Filters - Input EMI filters reduce electromagnetic interference or noise on the input side of the AC drive. EMI filters are needed for CE compliance.

GGS-EDRV Ethernet Drive Module

The GS-EDRV provides a high-performance Ethernet link between a control system and a GS2 drive. It mounts on DIN rail and connects a drive to an Ethernet hub or PC. The GS-EDRV processes input signals from the drive, formats the signals to conform with the Ethernet standard, and transmits the signals to the controller. The Ethernet interface also receives and translates the output signals from the controller and distributes the signals to the drive. The drives do not have a provision for shutting down control or power to the inverter in the event of a communications timeout. The GS-EDRV provides an onboard communication watchdog relay. This relay is used to disable control and/or power circuits if communication on either side of the Ethernet interface is broken or timed out. The timeout value is configurable. When the value is exceeded, the state of the relay changes. S-EDRV
