Product Description:

The SERVOSTAR-403M-CA servo drive is manufactured by Kollmorgen and belongs to the S400 Servo Drives series. It operates as the power stage in closed-loop motion systems, receiving command signals from a controller and supplying regulated three-phase power to a matched motor. Within an automation cell, it provides rapid current modulation, enabling tight position, velocity, and torque regulation for packaging, assembly, and material-handling machinery.

During continuous operation, the drive delivers a rated phase current of 3 Arms and can supply up to 9 Arms for short-term dynamic events such as acceleration or load shocks. The power electronics are clocked at 8 kHz, a switching frequency that reduces motor ripple while limiting transistor losses. Logic and interface circuits are powered from a separate 24 VDC auxiliary supply, isolating them from main bus fluctuations. An internal overvoltage monitor trips at 450 V to protect the DC link components. Thermal design accounts for 35 W of heat at rated current, which must be removed through panel ventilation. Four digital inputs and two digital outputs allow step, enable, and fault signals to be exchanged with the motion controller without additional I/O modules. This arrangement supports straightforward integration in systems that rely on discrete command and status wiring.

With a maximum installed load of 7 kVA, the drive can be placed on supply rails shared by multiple axes without exceeding typical cabinet power budgets. The output bridge tolerates motor windings between a minimum inductance of 12 mH and a ceiling of 75 mH, preventing excessive current ripple or sluggish current response. In standby, the electronic circuitry draws only 12 W, minimizing heat buildup when motors are idle. The housing measures 100 mm in width, 240 mm in depth, and 230 mm in height, and it weighs 3 kg, so it fits easily into standard 300 mm deep enclosures while keeping mass low for slide-out service access. Its compact form also helps preserve cabinet space for neighboring control and power components.
