Product Description:

The S30361-NA-ARM9 is a single-axis servo drive built by Kollmorgen and placed in the S300 Servo Drives series. It converts line power into a regulated three-phase output that governs motor torque and velocity in pick-and-place robots, feeders, and small gantries. Integrated processing controls current and velocity loops so that connected motors follow motion profiles from PLCs and motion controllers. This arrangement suits compact motion systems that need closed-loop speed and torque control without a separate control stage.

During operation, the drive accepts 110 to 230 V from the mains and uses protective shutdown at 455 VDC on the DC link. Motor windings receive phase current with a form factor of 1.01, which helps keep harmonic losses low. The continuous output capability is 3 A rms, and the converter switches at a base frequency of 8 kHz. In reduced-current mode, the carrier rises to 16 kHz to reduce acoustic noise. The control electronics, fieldbus, and sensor supply stay active on a 24 VDC auxiliary rail that must remain within tolerance for proper startup. With rated loading, the heat sink dissipates 35 W, while only 12 W are released when the power stage is disabled. The STO circuit disconnects gate signals to provide a certified torque-off response.

The drive communicates with higher-level controllers through a CANopen port and accepts four digital inputs plus two analog setpoints. Status is returned on two digital outputs for interlock or ready signaling. The bus link ceiling is 450 VDC, and connected motors must have at least 4.3 mH of phase inductance to keep current rise under control. Nominal power demand is 1.1 kVA at rated load, and the housing is only 70 mm wide for compact panel layouts. Two analog channels support velocity or torque reference modes, which gives the drive flexibility in basic command integration.
