COMPUMOTOR S Drive
Specifications
Direction Input
The direction input may change polarity coincident with the last step pulse. The direction input must be stable for at least 2 ms before the drive receives the first pulse.
Drive Temperature
131°F (50°C) measured at the heatsink fins. An internal thermostat will shut down the drive if the unit reaches 158°F (70°C) internally
Fault Output
Open-collector. Open emitter. 4N35. V:CE : 35VDC. VCESAT : 0.3VDC. Collector Current : 10 mA minimum. Dissipation : 100 mW maximum
Input Power
90VAC to 132VAC @ 50/60 Hz
Maximum Motor Winding Inductance
None (Compumotor recommends 50 mH measured in series or parallel)
Minimum Motor Hipot
500VAC
Minimum Motor Winding Inductance
2 mH (Compumotor recommends 5 mH measured in series or parallel)
Motor Temperature
212°F (100°C) maximum allowable motor case temperature. Actual temperature rise is duty cycle dependent.
Output Power High power
0.2 to 8A per phase at 170VDC
Output Power Low power
0.1 to 6A per phase at 170VDC
Output Type
Two phase MOSFET bipolar (H-bridge) switching at 21 kHz (nominal), pulse width modulated
Step Pulse Input
You must operate the step pulse input within the following guidelines. 200 nanosecond-pulse minimum. 40% - 60% duty cycle (2 MHz max pulse rate)
Features
- 16 DIP switch selectable motor resolutions (200 - 50,800 steps/rev)
- 2 MHz step input
- 90VAC - 132VAC, 50/60Hz power input
- A fault output to signal other equipment if a fault occurs
- High motor voltage (170VDC) operation for high-speed torque
- LED status indicators: power, step, undervoltage, overtemperature (latched), motor fault (latched)
- Microprocessor controlled microstepping provides smooth operation over a wide range of speeds
- Motor connector interlock to prevent connector damage
- Operates linear motor forcers
- Optically coupled step, direction, shutdown, and set zero phase inputs are compatible with all Compumotor indexers (25-pin D connector)
- Overtemperature and undervoltage protection
- Short circuit protection for phase-to-phase and phase-to-ground short circuits
- Three state current control for reduced motor/drive heating
- Uses low-inductance motors for improved high-speed performance (23, 34, 42 frame size motors available with torques from 65 - 2,400 oz-in)

HARD TO FIND A BETTER PROVIDER
Our company provides services to aid in the manufacture of technological products, such as semiconductors and flat panel displays, and often searching for distributors of obsolete product we require can waste time and money. Finding GID Industrial proved to be a great asset to our company, with cost effective solutions and superior knowledge on all of their materials, it’d be hard to find a better provider of obsolete or hard to find products.
Applied Materials
CONSISTENTLY DELIVERS QUALITY SOLUTIONS
Over the years, the equipment used in our company becomes discontinued, but they’re still of great use to us and our customers. Once these products are no longer available through the manufacturer, finding a reliable, quick supplier is a necessity, and luckily for us, GID Industrial has provided the most trustworthy, quality solutions to our obsolete component needs.

TERRIFIC RESOURCE
This company has been a terrific help to us (I work for Trican Well Service) in sourcing the Micron Ram Memory we needed for our Siemens computers. Great service! And great pricing! I know when the product is shipping and when it will arrive, all the way through the ordering process.

GO TO SOURCE
When I can't find an obsolete part, I first call GID and they'll come up with my parts every time. Great customer service and follow up as well. Scott emails me from time to time to touch base and see if we're having trouble finding something.....which is often with our 25 yr old equipment.
