DIGITAL
INPUT: Model 2767D
for applications up to 1 horsepower
These controls are easily interfaced to either microprocessors
or 8-bit parallel TTL logic level sources. Motor speed and direction
are determined by the value of a 8-bit parallel input: one bit for
direction and 7 bits for motor speed. Unused bits in lower resolution
applications may be tied off. Logic input signals are isolated from
the motor and power line with a minimum isolation voltage of 1500
VDC, reducing the possibility of grounding, noise or safety problems.
In addition, a failsafe circuit de-energizes the motor if the input
control power is not present. Diagnostic LEDs for user interface
and setup.
