Advanced Motion Controls DRQ series of digital drives can operate over SynqNet, a 100Base-T motion control network that allows users to deploy a multi-axis coordinated position control system using a centralized controller and distributed servo drives.
The SynqNet network technology, developed by Motion Engineering, replaces a conventional +/-10V and encoder interface with a high-speed digital interface. This allows servo drives to be mounted in the vicinity of the motor, thus reducing wiring cost and complexity, as well as providing a digital communications link to the drive for increased diagnostics and configurability.
Two models are available at present, the DRQ110EE15A8BDC and the DRQ110EE25A20NAC. The first model accepts a 20 – 80 VDC supply voltage and is capable of 15A peak output current, while the second model accepts an 110VAC supply voltage and is capable of 25A peak output current.
Both models incorporate a 20kHz Space Vector Modulation current loop, providing sinusoidal currents based on encoder and Hall or encoder-only feedback. Also incorporated are dedicated limit and home switch inputs, an E-stop input, and 2 user inputs and outputs. An additional feature is encoder broken-wire detection, which avoids run-away in case of encoder failure.
An RS232 interface allows configuration of all drive parameters, including current loop and commutation parameters, which facilitates operation with any rotary or linear servomotor.
