Metronix offers a family of servomotor drives designed to provide machine builders a platform to boost automation performance while also decreasing costs, according to the company. "The ARS 2000 SE drives combine advanced features including integrated functional safety, universal encoder interfacing and a peak current capability that is up to twice that of many similar drives on the market - allowing faster acceleration," said a company spokesperson. "At the same time, the drives reduce costs by providing only the features that a significant majority of system builders want, according to a survey of users."
"These servo drives integrate a high-performance position control capability but at a middle-market price," said Metronix's Frank Essmann. "We have 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 ARS 2000 SE family of compact panel/cabinet-mounting drives are available in a choice of six single- or three-phase continuous output power ratings from 0.5 to 6 kVA. They feature a compact design with integrated line and motor filters plus an integrated brake chopper and braking resistor. They are provided ready to use.
They also feature an increased overcurrent capability of four times the continuous output rating. "This compares with the approximately two times overcurrent rating offered by many other servo drive manufacturers," said the spokesperson. "The feature typically allows the speed of moves and the overall throughput of machines to be increased by factors from around 17 - 25%. Metronix's tests demonstrate that these drives provide overall increases in automation productivity of around 5 - 7% in typical continuous processing applications."
An additional feature is the integration of Safe Torque Off (STO) functional safety. This is provided and certified to Category 4/PLe according to EN 13849-1.
The drives also feature a universal encoder interfacing capability that allows connection to resolvers, analog/digital incremental encoders and single/multiturn absolute encoders such as HIPERFACE or EnDat. Standard communications interfaces include the CAN fieldbus, compatible with the DS 402 CANopen device profile. An SD card interface can be used to store firmware and operating parameters. The drives come in case sizes with widths of 54 or 69 mm (2.1" or 2.7").
Compared with Metronix's existing panel-mounting drives, the only significant features that have been omitted are an expansion capability in the form of two slots that accept plug-in modules - containing additional I/O, fieldbus interfaces, etc - and built-in power factor correction.
"The drives' built-in intelligence provides flexibility for system builders," said the spokesperson. "It allows engineers to create cost-effective drive-based solutions for many common applications requiring one or a few axes, or economic solutions for subsystems in processing equipment performing functions such as labeling or handling. Other common applications include functions such as synchronizing, sorting and a flying saw, and axes that automate auxiliary machinery functions such as set up and guarding. The drives can also be used in more complex multi-axis machinery and plant automation."
A Windows-based software tool for parameterizing and analyzing the new drives is available. For more complex applications, Metronix offers a motion controller that can be easily integrated.
