Internal Product Review
The S30101-PN is a Kollmorgen S300 servo drive with PROFINET RT communication. Speed regulation of 0.01% and 400 Hz velocity loop bandwidth support very clean motion response in demanding axes. STO (Safe Torque Off) adds strong integration value, making the drive an excellent fit for precise automation.

Product Description:
The S30101-PN is a servo drive manufactured by Kollmorgen for the S300 Servo Drives series. It conditions power from a three-phase AC source and delivers controlled current and voltage to a matched motor so that industrial axes hold position, follow velocity profiles, or generate constant torque as required by automated equipment. This drive also supports PROFINET RT communication, letting a PLC issue deterministic motion commands over a standard Ethernet backbone without additional gateways.
The device accepts an input range of 208–480 V AC and refreshes its current vectors every 62.5 µs, which keeps torque ripple low during rapid transients. Inside the inverter stage, the IGBTs switch at 8 kHz; this switching frequency balances dynamic response with manageable switching losses. The continuous motor supply is limited by a rated current of 1.5 A rms, while the incoming mains draw cannot exceed 1.2 kVA. A position loop closes every 250 µs, and the velocity loop reaches 400 Hz, yielding 0.01% speed regulation when the motor is properly tuned. Field-level integration is simplified by the PROFINET RT port, and motion commutation stays synchronized because the drive updates the velocity feed-forward table within each sample period.
The power section can operate on a DC bus up to 900 VDC, and short bursts of load inertia are handled by a peak output capability of 4.5 A rms. Excess kinetic energy is absorbed by a built-in 91 Ω brake resistor; this network can dissipate an internal regen power of 40 W, matched to the 40 W heat generated at full electrical load and the 12 W produced under quiescent conditions. Safe torque interruption is provided through the certified STO function, allowing motor torque to be removed without powering down the control electronics.
