Product Overview
Parker Compumotor's LN Drive is a self-contained microstepping drive that takes step and direction commands from an indexer through a 25-pin connector and runs a two-phase step motor from its own mains supply. The product label reads LN83-62, a code that also appears as a motor row in the drive's DIP switch table. A fan on the cover cools the chassis.

Frequently Asked Questions
Which motor does it match?
The product label reads LN83-62, and the DIP switch table on the drive lists the LN83-62 motor setting, alongside settings for other LN motors.
What line voltage does it run on?
95-135 VAC or 185-275 VAC, set by a selector switch, per the label.
What am I getting, and what am I taking on?
A used LN Drive that was powered up and nothing more, sold with the satisfaction guarantee. The photos are the spec for this unit. Flat-rate shipping in the lower 48, and orders over the free-shipping line ship free.
Compumotor drives from Rohnert Park still turn plenty of lead screws in labs that never saw a reason to change. If one of those axes is yours, this is the spare that keeps it moving.
