Description
The Yokogawa SR1008B62 is a high-precision, direct-drive servo actuator originally developed in collaboration with Parker Compumotor (DynaServ series). It provides closed-loop torque, velocity, and position control for high-accuracy industrial automation machinery, robotics, and semiconductor manufacturing equipment requiring zero backlash and high torsional stiffness.

Technical Overview and Deployment Constraints
The SR1008B62 utilizes direct-drive technology, eliminating mechanical transmission elements such as gearboxes, belts, and pulleys. This architecture removes mechanical backlash and hysteresis, enabling sub-arc-minute positioning accuracy in high-speed indexer or multi-axis positioning stages.
When replacing or retrofitting this unit, verify that the connected servo amplifier or drive controller matches the excitation and encoder feedback wiring configurations of the DynaServ interface. Because these legacy direct-drive systems rely heavily on precise tuning parameters (gain, inertia ratio, and loop filters), ensure controller parameters are backed up and verified before initializing motion commands.
Frequently Asked Questions
Q: Is the Yokogawa SR1008B62 compatible with standard third-party servo drives?
A: It is specifically engineered to operate with designated DynaServ-compatible servo drives (such as corresponding Parker/Compumotor or Yokogawa amplifiers). Verify drive signal compatibility and pinout configurations before integration.
Q: What maintenance is required for direct-drive actuators?
A: Direct-drive systems require minimal mechanical maintenance due to the absence of wear components like gears or belts. However, encoder health, grounding continuity, and connector integrity should be inspected periodically.
Q: Are replacement cables and mating connectors included?
A: Standard shipments include the base actuator unit only. Power and encoder cabling assemblies must be sourced separately unless specified otherwise in the specific surplus quote.
