Hitachi Introduces New Advanced AC Micro Drives


Hitachi America, Ltd., Industrial Components & Equipment Division, today announced the new WJ200 series of inverters. This new model advances the benchmark for performance and functionality in micro-size AC drives. The WJ200 is a sensorless vector (SLV) drive capable of 200% or greater torque across the speed range.  Speed regulation at low speed is dramatically improved – fluctuation is half that of previous models. Improved trip avoidance measures have been incorporated for unsurpassed system reliability and availability.

The WJ200 offers PLC-like functionality by means of the integrated Easy Sequence (EzSQ) programming function. Programs up to 1024 lines can be created on a PC using this structured language tool, and can then be transferred to the WJ200. In this way, very sophisticated control schemes can be created without the use of external controllers.

Simple position control applications are also possible with the WJ200 utilizing the integrated pulse input. Together with EzSQ, intricate motion profiles can be developed. Further adding to its flexibility, the WJ200 has the capability to drive both induction motors and permanent magnet (PM) motors – a single drive for two motor realms.

A new EzCOM peer-to-peer communications function is standard and allows multiple WJ200s to share data. One drive is designated as the “administrator,” and controls the network. Other drives on the network can be master or slave, with masters able to write data to any designated slave(s). Master/slave roles are rotated under the control of the administrator automatically. Up to 8 masters can reside on the network, and up to 32 drives (up to 247 drives, if external signal repeaters are used). The administrator can be master or slave also. EzCOM allows for creation of sophisticated coordinated systems without any additional external hardware or programming.

Other desirable standard features include a safe-stop function (meets ISO/IEC standards), password protection of parameters, real-time clock, standard Modbus/RTU RS-485 serial port, micro surge voltage suppression, dynamic braking circuit, and much, much more. The WJ200 is designed for long service with bus capacitors and cooling fans designed for 10 year life and varnish coating of circuit boards. The WJ200 also is RoHS compliant. Option boards will be released in the near future to allow communication via DeviceNet, CompoNet, ProfiBus, CANopen, and others.

Banner Engineering DF-G3 Discrete Fiber Amplifier Features World-Class Long Range Sensing Capability

Banner Engineering introduces its DF-G3 discrete long-range fiber amplifier with dual digital displays for use with plastic and glass fiber optic assemblies. Featuring increased sensing power, the DF-G3 can sense more than 3 meters (10 ft.) with opposed mode fibers or more than 1 meter (3 ft.) with diffuse mode fibers. The extra power provides increased detection reliability for dark targets at long range and enhanced detection sensitivity when using specialty fiber assemblies for large area and small part detection applications.

The DF-G3 is available with a single discrete output or two dual discrete outputs. The dual discrete outputs can be independently taught to trigger at different intensity values, which is ideal for correct part-in-place or error-proofing, bottle down, and edge guiding applications.

“We developed the DF-G3 fiber amplifier to meet our customers’ need to precisely detect smaller targets at longer ranges” said Dennis Smith, Senior Marketing Manager, Banner Engin…

TURCK M8 CORDSETS WITH 100 PERCENT SHIELDING OPTION PROTECT AGAINST EMI/RFI

TURCK is now offering the option to completely shield M8 picofast ® cordsets by connecting a braided shield directly to the coupling nut. This provides a cost-effective and reliable connection with 100 percent cable and connector shielding, which protects against electromagnetic and radio frequency interference.

The 3 and 4-pin cordsets are available with flexlife ® PVC or PUR jacketed cable. All connectors deliver IEC IP 67 protection.

The M8 picofast line, like most TURCK cordsets, provides male or female, straight and right angle connectors, standard and custom lengths, and pigtails or extensions. Fully encapsulated mating receptacles are also offered, completing the system.

TURCK’s BL Compact Family Collects Analog and Digital Signals at the Source

TURCK’s BL Compact system is a revolutionary modular I/O solution for collecting a variety of signals in a single, rugged node on a network. Rather than routing all signals through a control cabinet, this device makes it possible to obtain analog, digital, thermocouple, RTD, serial, RFID or a mixture of signal types in a compact, machine-mountable device over DeviceNet™, CANopen and PROFIBUS ®.

Up to two signals types can be combined in any combination in the BL Compact system, including RFID and analog, digital and serial—and more. The BL Compact system may be customized to suit a user’s specific needs, so that devices may be added to an existing network and signals may be gathered on the machine without an enclosure. This drop-in solution can be used to connect up to 16 devices—drastically reducing the time it takes to run wires for each device back to the control cabinet and the potential for wiring errors.

The BL Compact system is currently available with four, eight or 16 ports i…
