Product Description:

The SP10600-504A2 is a digital servo drive built by Kollmorgen and supplied in the SP Servostar Servo Drives series. The unit serves as an interface between an industrial controller and a brushless servo motor, converting low-power command signals into regulated three-phase outputs. In factory automation, it provides closed-loop current, velocity, and position control so machines can maintain accuracy under changing load or speed demands.

The drive processes an analog torque or velocity command with an input scaling of 1.70 A/V, so 1 V of reference corresponds to 1.70 A of phase output. Its command electronics are energized by a bipolar analog rail of ±15 VDC, which draws 320 mA, while digital management circuits run from an 8 V source at 0.2 A. Under continuous duty, the amplifier can deliver 6 A of regulated motor current, supported by a PWM carrier of 16 kHz and a measured current ripple band centered at 32 kHz. The drive supplies continuous power of 1.1 kW from 115 V single-phase mains and up to 2.2 kW from a 230 V three-phase line. Internal losses are limited to 84 W, and current feedback is scaled at 2.12 A/V for precise loop closure. These electrical characteristics support stable current regulation across changing motor loads without requiring an external current-control stage.

During transient loading, the inverter can supply 12 A for two seconds before returning to its continuous operating range. Thermal supervision forces a shutdown at 118 °C, preventing damage to the power devices during excessive heat buildup. An overvoltage trip at 430 VDC protects the DC bus from regenerative surges produced when the connected motor decelerates. At startup, the control board inhibits operation below 90 VDC, blocking erratic switching during brownouts. This protective response keeps the output stage disabled until the bus voltage is sufficient for controlled motor operation.
