DMCLDC BRUSHED DC SERVO MOTOR DRIVER
FEATURES • SPECIFICATIONS • DIMENSIONS • ORDERING
DRIVES
The DMCLDC driver is the solution for applications that require
a servo system, but do not justify significantly more expensive
brushless motors and digital servo drivers. This driver was designed
to drive the MRB series brushed DC
motors configured with a 2 channel
500 line encoder
to achieve positional
accuracy of ±3
counts and repeatability
of ± 1 count.
Features:
• 10 Amp power supply
• Line fuse protection
• Position feedback accomplished via a two channel (A&B) differential incremental
encoder for resolution of 1000 counts per revolution
• Proportional + Derivative (PD) feedback loop for closing the loop around the motor
• Final position error of ± 3 encoder counts
• Repeatability of ± 1 encoder count
• Position error L.E.D. (±127 encoder counts) and current trip faults.
• Current trip point potentiometer for setting torque fault limit
• Fault conditions via solid state Form “C” output (position error and current trip)
• Fault condition indication via 2 L.E.D.s to indicate current trip and position
error faults for field diagnostics
• Opto-isolated inputs, 5-30 Vdc (Pulse, Direction, Reset)
• Normally closed Reset input for clearing faults
• Pulse/Direction input for remote stepper controller
