Product Description:

The S30361-DN servo drive is produced by Kollmorgen and belongs to the S300 Servo Drives series. It is an AC-fed power stage that interfaces between a motion controller and a servomotor, translating command signals into precise voltage and current profiles. Within an automated line, the drive regulates velocity, torque, and position so actuators can repeat cycles accurately while safeguarding the mechanical load. The design targets mid-power axes on packaging, textile, and small gantry platforms where tight feedback loops and integrated safety are required but cabinet space and heat rejection remain limited.

At the power stage, the unit draws up to 1.1 kVA from the mains range of 110 to 230 V and converts it into a sinusoidal output that supports a rated motor current of 3 A rms with short bursts of 9 A rms for acceleration events. Pulse-width modulation occurs at an output stage switching frequency of 8 kHz, balancing dynamic response with electromagnetic compatibility. An external brake channel can continuously dissipate 0.3 kW during rapid deceleration, and the drive loses only 4 V across its output stage, limiting copper losses under load. Noise emission stays below 25 dB(A) for quiet cabinet operation.

As a control platform, the S30361-DN updates its current loop every 62.5 µs and the position loop every 250 µs for tight trajectory tracking. The DC link may reach 450 VDC, and a 66 Ω internal resistor absorbs regeneration when the external brake is unused. The integrated STO circuit shuts torque off by disabling the IGBT gates. Control logic is powered by a 24 VDC auxiliary supply and can report status over a DeviceNet option card. A reduced-current carrier of 16 kHz cuts switching loss, holding dissipation to 12 W when disabled and 35 W at rated load. The design permits 30 start-stop cycles per hour without affecting lifetime.
