Servo drives boost machine throughput, lower costs
A new series of 'intelligent' servo motor drives has been launched that is claimed to offer machine builders a platform to boost the performance of automation while also decreasing costs.
The ARS 2000 SE drives from Metronix combine integrated functional safety, universal encoder interfacing and a peak current capability that is said to be up to twice that of many similar drives on the market - allowing much faster acceleration.
"The new servo drives integrate a very high performance position control capability but at a middle market price," said Metronix's Frank Essmann. "We've managed to reduce costs by up to 15% compared with our existing ranges, by carefully matching functions to the needs of a majority of our OEMs and automation engineer customers."
The drives are available in a choice of six single or three phase continuous output power ratings from 0.5 to 6kVA. They include an integrated brake chopper and braking resistor; an increased over current capability of four times the continuous output rating; and Safe Torque Off (STO) functional safety.
The devices also feature a universal encoder interfacing capability that allows connection to resolvers, analogue/digital incremental encoders and single/multi-turn absolute encoders such as HIPERFACE or EnDat.
