OEM770T is Parker Compumotor OEM770 series single-axis torque-mode servo amplifier, designed for OEM machine builders and precision motion applications. It supports both three-phase brushless DC servo motors with Hall sensors and traditional brushed DC servo motors, operating under torque command controlled by external motion controller. Widely used in automated assembly, semiconductor handling, rotary indexing equipment and precision positioning machinery. It is an end-of-life spare part for legacy Parker motion control systems.

This compact 3U Eurorack form factor drive adopts IP20 protection class for cabinet installation, powered by 24 to 75 VDC power supply. It delivers continuous output current 6A and peak current 12A, with three-state current control technology to reduce motor heat and improve efficiency. It uses six-state commutation for brushless motors, and provides +5VDC power supply for motor Hall sensors. The 25-pin D-Sub connector handles command input, encoder feedback and digital I/O signals, while right-angle screw terminals simplify power wiring and allow side-by-side dense mounting inside control cabinets. Transconductance torque control accepts analog voltage command signal to adjust output torque linearly.

Two status LED indicators on front panel show power ready and fault alarm information for fast on-site troubleshooting. Built-in multiple protection circuits include short-circuit protection, overcurrent, overload and undervoltage protection. Current foldback function limits continuous thermal load to prevent motor burnout during long-cycle operation. Configuration parameters such as peak current and foldback current are set via plug-in resistors. The operating temperature range is 0~50℃, stable for continuous running in industrial cabinet environments. It works with dedicated Xware software for drive commissioning and signal monitoring.

OEM770T is obsolete Parker servo drive spare part. Many legacy automated machines still adopt Compumotor OEM770 motion platforms. When the original torque amplifier fails, replacement with identical OEM770T can reuse mounting holes, power cables, motor wiring and existing control configuration. Technicians install the drive, complete wiring verification and test torque response, so single-axis servo motion control system resumes operation and reduces production downtime.

Before shipment, every OEM770T undergoes comprehensive functional inspection including power-on self-test, current output test, Hall sensor power verification and insulation resistance test. All products come with 12-month warranty. Our automation technical team provides remote support for installation, wiring guidance, parameter setup and fault diagnosis. Fast global shipping available for urgent maintenance orders.

For automation maintenance engineers and system integrators, OEM770T is reliable spare torque servo amplifier for legacy Parker Compumotor motion systems. It restores precise torque control for brushed and brushless servo axes, maintains machine positioning performance, extends service life of automation assets and avoids whole mechanical axis renovation.
