An electric servo drive is the control unit that powers and controls the movement of a servo motor and drive system. It regulates torque, speed, and position so machines can accelerate quickly and maintain a stable performance, before they slow down accurately and come to a controlled stop. This level of control is essential in machine and system building and helps engineering teams achieve accuracy, repeatability, and consistent product quality.
You’ll find servo drives across centralized and decentralized architectures, supporting everything from straightforward single‑axis positioning systems to complex rotary, cross, or multi‑axis ones. Modern versions go even further: they combine motion control with multi‑protocol communication and integrated safety functions, making them an excellent fit for today’s flexible, connected, and safety‑compliant machine designs.
Safety-certified servo drives play a crucial role in protecting operators, machines, and processes. As functional safety requirements increase, engineers need drive systems that deliver high performance while reducing risks at the operational level.
To support this, our electric drives with functional safety provide:
A broad range of safety functions helps machine builders meet demanding standards while keeping engineering efforts manageable. These include key functions such as:
Together, these functions provide safer commissioning, smoother operation, and greater flexibility when designing compliant machine architectures.
