Universal servo drives suit multiple encoder systems and motor types
03 May 2015
Motor Technology's range of ARS 2000 SE servo drives, manufactured by Metronix, are simple to install and configure on a wide variety of applications.
These units can be used universally as they automatically identify motor parameters and encoder types, and are manufacturer and system independent.
The standard edition, or SE, range of drives within the ARS 2000 family 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 much faster acceleration.
At the same time, the drives reduce costs by providing only the features that the majority of OEMs, system builders, and automation engineers want. They provide a high-performance position control capability at a middle-market price and reduce costs by up to 15% compared with other drives in the Metronix range.
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 ethernet port can be utilised for set-up and commissioning, locally or remotely, and for communication with host controllers during operation. They include EMC filters and regen resistors and can be operated direct-on-line (CE and EN compliant) without additional equipment.
There is also an SD Card interface that can be used to store firmware and operating parameters. This allows the drives to be commissioned very easily, and facilitates an easy change-out by maintenance engineers without the need for a sophisticated parameter setting software tool.
The drives' built-in intelligence provides enormous flexibility for system builders. It allows engineers to create highly cost-effective drive-based solutions easily for many common applications requiring one, or a few axes, or economic solutions for subsystems in processing equipment performing functions such as labelling or handling.
Other common applications include functions such as synchronising, sorting, 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 that can be designed in a flexible way.
