SJ700 Series AC Variable Speed Drives

• Brochure/Catalog
• Instruction Manual
• Quick Reference Guide

High starting torque (150% at 0.3Hz) - Improved sensorless vector control & auto auto tuning provide for high starting torque of 150% or more at 0.3Hz. Easy adjustment of motor constants meets the needs of high torque applications, such as cranes, extruders or lifts.

Tripless operation - A high speed internal processor improves current control performance. Over-current suppression and over-voltage suppression functions help avoid inverter tripping during acceleration and deceleration.

If you are looking for Hitachi L700 AC Drives, please call us on (800) 894 - 0412 or email us at info@clrwtr.com we will do our best to help you find the Hitachi L700 Inverters that you are looking for at the most competitive prices possible. If you are searching for Hitachi L700 VFD technical information (data-sheets) please use the datasheets or product selection guide page links.

Built-in PLC-like programming functions - Sequence operation is realized by downloading to an inverter a program created with Hitachi's EzSQ software. Tailor inverter operation to meet changing process requirements, and replace separate PLCs in some cases. By simplifying or eliminating external hardware, signficant cost savings can be achieved. Password function is incorporated to provide security for proprietary program data against loss or unauthorized modification.

Long-life components & lifetime warning function - Life of DC bus capacitors & cooling fans is 10 years or more (design life). Life can be monitored via the display, and an output can be activated to notify when maintenance is due.

Ease of Maintenance - Field replacement of cooling fan(s) and DC bus capacitors can be accomplished in a fraction of the time. Using Logic terminal move to SJ700 without wiring change. Read SJ300 Parameter by SRW remote operator and write them in to SJ700.

Network compatibility - A serial RS-485 Modbus-RTU port is standard. The SJ700 can communicate with DeviceNet, PROFIBUS-DP, and other networks with communication options.

Global Standards

• Conformity to global standards - CE, UL, c-UL, c-Tick approvals.
• Sink / source logic is standard - Logic input and output terminal can be configured for sink or source logic.
• Wide input power voltage range - Input voltage 240V for 200V class and 480V for 400V class as standard.

Environmental Friendliness

• Micro surge voltage suppress function (Patent registered)
• EU RoHS compliant
• Improvement of environment
