Motor Technology introduces ARS 2108 drives

A Motor Technology product story
Edited by the Engineeringtalk editorial team Mar 17, 2009

Motor Technology has launched the latest addition to German company Metronix's ARS series of compact servo drives in the UK.

The ARS 2108 features faster processor speeds - up by 60 per cent - cutting current loop time to 31.25ms.

This is said to be particularly beneficial for direct drive applications.

Additionally, the drives deliver fast field-bus cycle times of up to 125ms for Sercos II, enabling tighter speed and torque control.

This is claimed to be important for applications such as machining, where the quality of the machined finish is dependent on a high level of speed and torque control.

The ARS 2108 drives are also said to offer a high overload capability of up to four times the nominal current.

In some applications, this will result in cost savings as the units' ability to cope with the higher peak currents of motors means that, in some cases, a lower rated drive could be selected.

Other key features of the ARS 2108 include: integrated CE filters; a universal encoder interface; compatibility with a range of motors; automatic motor identification; field-bus support; extensive input/output; and commissioning software.
