Fully Integrated Controller and Brushless Servo Drives For High Volume Applications

The OEM670X and OEM675X were designed for the needs of OEMs and high-volume users with a fractional horsepower motion control application. Compumotor’s OEM670X and OEM675X fully integrated servo systems combine the power, compact packaging, and reliability of the OEM670T/OEM675T 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 OEM670X and OEM675X are 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.

Although the current and voltage are the same for the OEM670 and OEM675, the OEM670’s current compensation loop is optimized for NeoMetric and J Series motors; the OEM675’s current compensation loop is optimized for SM and SE motors. We recommend that you use the OEM670 with NeoMetric and J Series motors, and use the OEM675 with SM and SE motors. This provides optimum system transient response for better system performance (easier tuning, better settling time, etc.).

Features
