Product Description:
The 01.S4.D2E-3011 is a digital servo controller supplied by KEB within the S4 Combivert Servo Controllers series. Intended for compact axis control, this unit regulates the current, speed, and position of permanent-magnet synchronous motors used in conveyors, small gantries, and pick-and-place stations. It interfaces with higher-level PLCs, converting command data into precise drive signals while monitoring feedback to maintain stable motion profiles in industrial automation. This operating profile makes it suitable for machines that need repeatable motion in a compact control package.
Its control electronics sample incoming setpoint values through a 12-bit analog input channel, allowing 4096 discrete steps for speed or torque references. Actuator feedback to external devices is issued through an 8-bit analog output, which is suitable for simple process indication. Fast loop execution is enabled by a current control update every 64 µs. Speed corrections are recalculated every 128 µs, so transient load changes are damped quickly and command tracking remains responsive. When supplied from a 200 V class DC link, the drive delivers a rated mechanical shaft speed of 3000 rpm with stable regulation. This voltage class also matches common mains rectifier arrangements. For continuous duty, the basic torque reaches 0.8 Nm, while thermal design limits stall current to 1.35 A.
The controller supports a motor rated at 0.25 kW and can provide a continuous phase current of 1.15 A. Momentary overloads are absorbed as a pulse torque of 4.0 Nm for rapid acceleration, and rotor inertia of 1.1 kg·cm² helps keep oscillations small during these events. End-of-shaft loading may reach 310 N axially and 400 N radially without compromising bearing life, which supports belt loads, couplings, and similar mechanical connections. Stall torque is maintained at 0.95 Nm when the shaft is locked. The assembled controller and matched motor package weighs 3.1 kg, which helps it fit light machine frames without adding excessive mass.
