The MotionPod is a flexible 1-4 axis motion controller with an internal power supply and either microstepping or servo motor control, all integrated in one efficient package. Based on proven, high-performance Galil motion control technology, the MotionPod is suited to multi-axis system and machine motion control, saving space and cabling.
Available in either a panel mount enclosure or with a front panel as a standard 2U high 19″ rack mount, the MotionPod accepts a supply voltage from 90 to 240 Volts, 50/60Hz.
A full range of Galil motion control commands allow many modes of both simple and complex control of stepping motors and brushed or brushless servo motors in a system. Both Ethernet10Base-T and RS232 communication is provided. The MotionPod incorporates a 32-Bit microcomputer and provides such advanced features as PID compensation with velocity and acceleration feed-forward, programme memory with multitasking for simultaneously running up to 8 programmes and uncommitted I/O for synchronising motion with external events.
The hardware interface to motors, encoders, digital inputs and outputs and analogue inputs is provided through standard DSub connectors on the rear panel. Internally, emergency stop and braking functions, when required, are also catered for. An optional MotionLink multi-axis joystick unit can also be connected.
The MotionPod is an economical and very capable multi-axis motion controller for almost any application where reliable and flexible control of motors is required.
