100 MOTOR CONTROL is a half wave (four quadrant) regenerative unit
that controls the speed and direction of shunt wound or PM motors
with outputs ranging up to 1/8 HP.
These controls are designed to be easily interfaced to microprocessors
or TTL digital circuitry. Logic input signals are opto-isolated
from the motor and power line circuits with a minimum isolation
voltage of 1500 VDC. This eliminates crosstalk, ground loops, and
other noise problems.
An eight bit parallel logic command (negative true) selects motor
direction as well as motor speed with 7 bit (one part in 128) resolution.
A failsafe circuit de-energizes the motor if control power is not
The Model 100 operates from a nominal 115 VAC, 50/60 Hz power source,
and drives DC motors with 90 VDC rated armatures. A field circuit
can provide either 50 VDC or 100 VDC for shunt wound fields.
The units are of open frame construction. Connections to the digital
inputs may be made via a standard insulation displacement ribbon
connector, or by solder eyelets. Connections to the motor and power
line may use a plug-in screw terminal barrier strip, or solder eyelets.
