SPS IPC Drives 2014 exclusive show report

Baumüller was also showing several extensions to its motors portfolio. For example, it now offers a water-cooled version of its DSD2 56 permanently excited servomotor, providing much more power than its air-cooled or non-ventilated designs. There is also a new 132 frame size in the DSD2 range, with a nominal torque rating of 500Nm, a peak rating of 1,000Nm, and a top speed of 4,500 rpm. The new size is available in an IP54 air-cooled version and a water-cooled version, to be followed soon by an oil-cooled version. Finally, Baumüller is now offering oil-cooled versions of its DS2 motors (below) in sizes 100–200, and plans to extend this option to its DST2 series.

On a stand dominated by the Emerson Industrial Automation identity, Control Techniques introduced a safety module for its Unidrive M600 and M700 drives. The SI-safety module, which is TÜV-approved to SIL 3, supports various safety options including SS, SOS, SLS and SLP. CT’s SafePro software can unlock full safe-PLC capabilities, allowing users to develop their own safety function blocks for advanced applications by combining various elements.

Danfoss has expanded its ISD 510 range of integrated servodrives to support the real-time Ethernet systems, EtherCat and Powerlink. The decentralised drives are based on permanent magnet synchronous motors with integrated electronics. A central power supply can support up to 64 drives, each capable of delivering up to 13Nm of torque.

Danfoss is also offering a ProfiSafe option module for its FC302 AutomationDrives, which provides safety to SIL 2 / PL d. The MCB 152 module can activate the drives’ integrated safety functions from any ProfiSafe host.

Kollmorgen has doubled the maximum output current of its AKD family of servo amplifiers from 24A to 48A. The company is promoting the more powerful system as an efficient alternative to complex centralised hydraulic drive systems.

Lenze was showing two ranges of IE3 motors that are the same size as IE2 machines but consume up to 20% less energy. The fixed-speed m200-P motors cover the power range 5.5–45kW with a choice of operating voltages. The m500-P motors (below) cover the same power range but are optimised for use with inverters and can also be operated directly from the mains. Lenze says that the new motors will usually pay for themselves within two years.

The Korean automation supplier LSIS has a new range of HVAC drives covering ratings up to 90kW. The compact LSLV H100 fan and pump drives can be mounted side-by-side and support BACnet as standard (with LonWorks as an option). They offer functions including soft fill control, multi-motor control and a fire mode.

Mitsubishi Electric has added IP55-protected dust- and splash-proof versions to its FR-A800 series of frequency inverters, with outputs from 400W–160kW. The drives can operate either asynchronous or IPM/ISM motors and have maximum operating frequencies of 400Hz. They have a 250% overload capacity and speed rise times of less than 80ms. They support 11 network options.
