Bayside Motion Group reckons its i-Drive family of digital servo drives represents a cost-effective solution for high performance applications.

Bayside Motion Group reckons its i-Drive family of digital servo drives represents a cost-effective solution for high performance applications.

The drive is a complete point-to-point digital amplifier available in seven models with power ratings ranging from 0.5 to 3kW.

The drive can be used for both velocity and position control of synchronous and asynchronous motors and is CANbus compatible.

The drive's compact digital signal processing technology uses a patented vector based sensorless field algorithm that permits high power output from a package that fits the palm of a hand.

The user-friendly front panel LCD display and six function/programming pushbuttons allow for entering all the control, system and motor parameters, set points and error flags.

Optional simulation software for programming and operation has a PC display showing a functional block diagram, a motion profile configuration window, wiring and connection pin assignments, and full diagnostics capability.

The i-Drive is rugged because it is packaged in a protective steel enclosure that was originally developed for high reliability automotive applications.

A special chip, which works together with the power components, guards against current surges, ground faults, short-circuits and power supply failures.

The drive is vacuum encapsulated and vibration-proof.

The power section of the amplifier uses a patented chip-on-chip hybrid assembly that is manufactured in a clean room environment.

This module forms the rear wall of the amplifier that bolts directly to the customer's frame and ensures excellent thermal dissipation, which allows for a higher power rating in a smaller package.

The i-Drive features: power levels of 500, 750, 1500, 2200 and 3000W from 115 and 230V single-phase and 400V three-phase supplies; patented vector based sensorless field technology; compact size with integrated display; programmability via keypad or PC-based simulation software; five operating modes; external velocity and torque control using +/-10V DC signal lines; digital position, torque and velocity control; and both CANbus and serial multidrop RS485 connectivity.
