Compact, Low-Cost Solutions.

The Making of a Servo System:

Servo systems rely on feedback devices to continuously correct for errors in current or torque, velocity, and position. A typical servo system includes a servo controller, amplifier, and motor with a feedback device. The servo amplifier can have varying degrees of complexity and performance. A torque amplifier (e.g. OEM770T) controls only the current loop. A positioning servo (e.g., OEM770X) accepts encoder feedback to close the position loop.

The OEM770 Family:

The OEM770 family of products bring high performance in a small, low-cost package. The OEM770 family offers a costeffective solution to a number of fractional horsepower brushless servo applications. The OEM770 family was designed to operate with Compumotor’s SM, SE, NeoMetric, J and BE series of motors or any standard three-phase brushless DC servo motor equipped with Hall effect sensors. The OEM770 family uses three-state current control for efficient drive performance and cooler motor operation. The OEM770 family products are small and convenient to use. Units install with only two screws (the screws also provide grounding and captivate the cover). Their right-angle screw terminal allows side-by-side mounting, and their small footprint maximizes cabinet space. The snap-on molded cover is removable for system configuration and helps provide a barrier against environmental contamination. The drives are the same size as a 3U Eurorack card. Their standard 25-pin connector is compatible with universally available connectors.

Computer Programmable Standalone Servo Drive/Controllers:

Compumotor’s OEM770X drive/controllers are standalone, fully integrated servo systems for fractional horsepower applications. Designed to provide greater flexibility and user convenience, the single-axis OEM770X incorporates a built-in RS232C based controller in the same small package for quick, easy programming. Users can program seven sequences and utilize five programmable inputs and two programmable outputs per unit



Compumotor’s OEM770 Series of servo drives were designed for the needs of OEMs and high-volume users with a fractional horsepower motion control application. These products were developed to provide performance, compact packaging, reliability, and power. The OEM770T is a torque amplifier utilizing a ± 10VDC analog input making it directly compatible with industry standard motion controllers.

Features:

• Single 24-75 VDC power supply input.

Fully Integrated Controller and Brushless Servo Drives

The OEM770X is designed for the needs of OEMs and high volume users with a fractional horsepower motion control application. Compumotor’s OEM770X fully integrated servo systems combine the power, compact packaging, and reliability of the OEM770T torque servo amplifiers with a simple, programmable, built-in, RS232C-based servo controller. Users can program seven sequences and have five programmable inputs and two programmable outputs per unit. The OEM770X is ideal for less demanding motion control applications such as rotary indexing, step-and-repeat, and linear positioning. The “X” version is a cost-effective, single axis servo system to meet your high-volume application needs.

Features:

Performance

• Servo controller and drive in one small package

• Standard RS-232C serial communications interface

• Optional 2 kBytes of battery-backed RAM to store up to 7 command sequences (-M2 option)

• Daisy chaining up to 256 units on one serial port

• Five programmable inputs for remote sequence select, trigger, and home limit, and two dedicated limit inputs

• Two programmable outputs for machine interaction

• Operates with standard differential, optical encoder for velocity and position feedback

• PID control algorithm used for servo tuning

• Several AC Brushless Servo motors are available from Compumotor providing up to 190 oz-in continuous and 570 oz-in peak torque.

Reliability

• Short-circuit protected: phase-to-phase, and phase-to ground

• Overvoltage circuitry protects the drive from large inertial loads
