WJ200-075HF Hitachi

Note: The WJ200-075HF is a legacy part and, despite continued limited availability, it is not recommended for new systems. The WJ200 line has been replaced by the WJ-C1 series, which has been explicitly designed for easy retrofitting. An equivalent drive in the WJ-C1 line has an identical footprint and parameters can be copied from drive to drive.

Overview

A member of Hitachi's WJ200 family, the WJ200-075HF is an AC inverter /w/ a 3ph 380...480VAC supply -15%...+10% @ 50/60Hz and an output of 7.5kW, 10HP, 18A.
Features advanced sensorless vector control with a high starting torque of 200%, enabling use in crane and hoist applications. All models come standard with a dynamic braking resistor and operator keypad, with an expanded interface available via USB.
In addition, the WJ200-075HF has great speed regulation even at low speeds and trip avoidance functions for overcurrent situations. As an added bonus, WJ200 drives are capable of driving both induction motors and permanent magnet (PMAC) motors.

Terminal Information

Sink/source logic configurable via short bar.
7x DI (24VDC nominal, 27VDC max. allowable; 18VDC min. in source mode, 3ΔVDC max. between terminal and common in sink mode).
2x DQ (24VDC nominal; 50mA max. @ 4VDC max. in source mode, 27VDC max. in sink mode).
2x AI (10VDC nominal, accepting current or voltage input; 0...9.8VDC input in voltage mode, 10kΩ impedance; 4...19.6mA input in current mode, 100Ω impedance).
1x AQ (2mA max. @ 0...10VDC)

Physical Characteristics

IP20 rated enclosure; 260mm x 140mm x 155mm (HxWxD), approx. weight of 3.5kg.
Rated for operation between -10°C...+50°C @ 20...90% relative humidity, non-condensing.
Suitable for installation at altitudes <=1000m above sea level, in an indoors environment and free from corrosive gases, oil mist and dust.
Designed to enable side-by-side installation, saving space within in the panel. In this configuration, ambient temperatures should be <=40°C.

Programming

WJ200 inverters support Hitachi's EzSQ programming language, enabling sequence operation.
User programs can be compiled on EzSQ software on a PC, eliminating the need for external components to save costs.
An example of this could be configuring motor speed cycles to run faster during off-peak hours to take advantage of cheaper electricity costs.

Communications

The WJ200-075HF comes equipped with Modbus-RTU communications over RS-422 as standard, and can be fitted with option modules to enable communication over other protocols, name Profibus, PROFINET and EtherCAT.
Additionally, P2P communication is supported via EzCOM, wherein one drive acts as administrator and the other drives act as master or slave.
