MC1451A Datasheet | PMD

Features Advanced control of up to 4 step motors per chipset High speed pulse and direction output S-curve, trapezoidal, velocity contouring, and electronic gearing trajectory modes Optional incremental encoder feedback Software & feature patible with other versions of PMD's chipset family Available in 1, 2, or 4 axis configurations 32-bit position, velocity, acceleration and jerk trajectory profile registers Pulse and direction output for each axis at up to 1.5 Mpulses/sec On-the-fly stall detection Two travel-limit switches per axis External motion breakpoint per axis Intelligent easy-to-use packet-oriented mand protocol Programmable pulse output modes Chipset Developer's kit available MC1451A, MC1451A-E MC1251A, MC1251A-E MC1151A, MC1151A-E General Description The MC1451A is a dedicated motion processor which functions as a plete chip-based step motor controller. Packaged in a 2-IC chipset, this device performs trajectory generation and pulse and direction signal generation for use in a wide variety of stepper-based systems. The MC1451A provides an optional third IC which allows incremental encoder signal input for position verification and on-the-fly stall detection. The MC1451A is available in a one, a two, and a four-axis configuration. The MC1451A is functionally similar to other PMD motion processors however it is dedicated to the control of step motors, instead of servo motors. All of these devices provide sophisticated trajectory generation and synchronization features allowing the creation of plex motion sequences. Typical Configuration Host Processor Amp M E Axis 1 In addition to pulse and direction circuitry which can output at up to 1.5 megapulses per second the chipset provides two limit switches per axis, a programmable external signal breakpoint per axis, and an 'At Rest' output signal. The chipset is controlled by a host processor which interfaces with the chipset via an 8-bit bi-directional port. munications to/from the chipset consist of...
