Product Description:

The SR03200-000000 is a servo drive manufactured by Kollmorgen as part of the SP Servostar Servo Drives series. Designed to supply regulated power and closed-loop control to brushless servomotors, it converts a DC bus into high-frequency PWM output while processing position, velocity, and torque commands from a motion controller. Within industrial automation cells, the unit interfaces with resolver feedback to manage tightly synchronized axes in packaging lines, pick-and-place gantries, and general machine-tool feeds.

When operated from the 325 VDC bus, the drive delivers up to 1.1 kVA of continuous electrical power, whereas it sustains 0.55 kVA on a 165 VDC supply. The continuous output current is 3 A RMS, and transient demands can be met with a peak current of 6 A RMS. Pulse-width modulation occurs at 16 kHz, and a 32 kHz reconstruction filter limits phase current ripple, reducing torque pulsation in low-inductance motors. The control loops are refreshed quickly; the velocity loop executes every 250 µs, and the position loop closes every 500 µs, providing rapid disturbance rejection. Internal losses produce 37 W of heat, and the overtemperature threshold is set to 118 °C.

Command fidelity starts with a 14-bit differential analog input that the drive converts into torque or speed references. Combined with resolver position data and digital filtering, this input supports long production runs with drift held to 0.01% of the set speed. The power section disengages if the bus rises above 430 VDC or falls below the 90 VDC undervoltage limit, protecting both the drive and the connected motor. A thermal latch keeps the output stage inhibited until the heat sink cools after an overtemperature trip. The housing weighs 2.85 kg, easing installation on DIN rails or in compact cabinets while maintaining the vibration tolerance expected for continuous-duty servo axes.
