NEW SERVO DRIVE IS SIMPLE
23 February 2004 - Lenze Limited

The new range of SimpleServo drives is both simple and economic. Designed and manufactured to meet the global marketplace for machine automation, SimpleServo is a range of compact drives with rated outputs from 4 to 10 amps, peak currents up to 30 amps. Particular features are options of a positioner version, Ethernet of CANopen high-speed bus communications, and the easy-to-handle EPM memory chip.

SimpleServo is aimed at the growing market for high-speed machinery with decentralised drives, for example packaging, pick and place, and semiconductor handling machinery. Dynamic performance is available in torque, velocity or electronic gearbox modes with peak currents of 300% nominal for up to 2 seconds. High-speed bus communications for precise control are possible through Ethernet or CANopen, and resolver or encoder feedback is possible. Yet the dimensions of SimpleServo are small, with the largest 12 amp drive being only 115 wide, 190 high and 190 deep. Programming is easy using free MotionView software with BASIC type commands.

The PositionServo version of SimpleServo adds the ability to program precise motion profiles and avoids the need for a separate PLC or motion controller. Ratings and dimensions are the same, and compared to SimpleServo, the PositionServo models have extra I/O. Low cost combines with high performance as PositionServo has 64 bit processing and reaction times as short as 2 microseconds.

All SimpleServo models feature the unique EPM memory chip, which gives easy programming. This chip plugs by hand into the front of the drive and holds all the parameter setting. It can be copied or programmed through a hand-held and battery powered programming unit. Actual time taken to copy a chip is less than 3 seconds. The new chip can then be plugged into a drive even without powering it up, and the drive is then ready to go.

Extra features available with SimpleServo and PositionServo include pre-configured power and communication cables to speed build times. Matching synchronous motors can be supplied with IP54 or IP65 enclosure. The requirement for technical support on these easy to use products is minimal, but telephone and on-site advice is available.

The new SimpleServo and PositionServo ranges combine value, compact dimensions and ease of use. They are easy to program and easy to handle with the unique EPM memory chip. With 64 bit processing and high-speed bus options, the dynamic performance is particularly high.
