Servo drive eases distributed automation

LG Motion product story

Measuring under 78 x 78 x 32 mm, the microMaxR intelligent servo drive can be mounted very close to the motor on any automated machine with short motor power and feedback cabling.
Agile Systems' microMAXR intelligent servo drive combines a sophisticated motion controller with user I/O, a powerful servo amplifier and a choice of high-speed networking in a single compact package for cost-effective distributed automation.
The new DSP-based intelligent drive makes full use of Agile Systems' digitalPower core drive technology, an alternative to traditional hardware-based multi-axis motion control systems with centralised PC-based controllers.
Agile Systems' peer to peer network architecture allows individually created programs on several controllers to interact, providing a true distributed control network scheme.
Register values are exchanged and synchronised between controllers at a defined point in time, allowing completely co-ordinated motion and machine control.
Measuring under 78 x 78 x 32 mm, the microMaxR can be mounted very close to the motor on any automated machine with short motor power and feedback cabling, and with a network taking care of positioning and machine control commands.
This design scheme eliminates the need for long runs of noise-susceptible wiring and with a potential cabling reduction of up to 60%, reduces assembly time and drives down costs.
The 90V DC powered drive stage features a 20kHz current loop in a choice of 5A and 15A continuous current ratings.
Designed with flexibility in mind to suit a wide choice of motor and feedback technologies, both trapezoidal and sinusoidal commutation options are included for brushed, brushless and voice-coil motors.
Open loop stepper motor control is also provided.
A 4kHz, PID position loop with multiple filter compensation supports incremental, analogue, absolute and Endat encoders.
The networking and communication capabilities of the microMAXR include Firewire BCAT5 and Ethernet, which can be used for high-bandwidth control with high-resolution PVT (position/velocity/time) commands over multiple modules.
A high-speed RS485 deterministic port and RS232/422 ports are also included.
Agile Systems' DP-WinT graphical environment application software is used for configuration, tuning and analysis as well as high-level motion and machine control programming using Agile's own language.
The MAXCLibT is an ANSI C library that supports C and C++ users across all hardware platforms and includes functions and registers for all motion commands, scanned events, timed events, program flow and conditional events.
With a full complement of analogue and digital I/O, including a high-speed position latch and high current outputs, the microMAXR is available in two packaged versions to support locking connectors or backplane interfacing.
The -LC locking connector version will suit customers who require the convenience of individual connectors for motion, feedback, communications and other functions and can be supplied with an accessory pack of mating connectors and cabling.
The -BP backplane version includes an 80-pin and a 40-pin connector, allowing customers to interface the microMAXR directly to their own PCB board, drastically reducing machine wiring and assembly time.
