Overview
The MOT module easily interfaces with
industry standard motion sensing and positioning hardware, providing
up to 4 axes of motion control.
The MOT Module is ideal for Motion
Control, Motion Measuring, DC Servo's, Servo Loop Control.
It may be combined with other analog
OMNIBUS modules on a DSP baseboard to create a single, integrated
data acquisition/motion control system, for process control, servo
applications and embedded systems.
The input stage accommodates normal and
quadrature position decoding, with multiple independent index, home
and limit sensing. The outputs support stepper and DC servomotor
control. The stepper control logic consists of two parts: the
DDS-based stepper frequency generator and the output formatting
logic, both programmable from the host DSP.
Analog outputs are provided with Analog
Devices AD669 16-bit D/A converters for generating drive signals in
DC-servo applications at up to 200kHz. Programmable stepper
fail-safe conditions and an “Amp Enable” command provide for
hardware-based safety interlocks. |
