Product Description:
The SP10600-402B2 is a three-phase servo amplifier produced by Kollmorgen within the SP Servostar Servo Drives series. The unit converts a regulated DC link into phase-correct sinusoidal currents for brushless motors and routes feedback to the motion controller. Positioned between the controller and motor, it establishes closed-loop torque control that supports accurate positioning and velocity regulation across packaging, printing, and pick-and-place machinery.
Rated for a continuous phase output of 6 A RMS per phase, the drive delivers stable torque during normal operation, yet it can supply 12 A for up to two seconds to overcome acceleration peaks. Current is synthesized by a PWM bridge that switches at 16 kHz; the motor terminals therefore receive a ripple component centered at 32 kHz, minimizing audible noise while keeping the magnetic components compact. Even at that switching rate, the current waveform form factor remains at or below 1.01, indicating limited distortion of the commanded sine wave. Thermal loading created by the conduction and switching devices results in internal power dissipation of 84 W, which must be removed by cabinet airflow. Adequate ventilation around the amplifier helps prevent excessive heat from accumulating during sustained operation.
The command interface is powered by an ±15 VDC analog rail that can provide 320 mA to external potentiometers or summing cards. Within this range, torque requests are interpreted at 1.70 A/V, while feedback signals are processed at 2.12 A/V to maintain balanced loop gains. The control electronics operate from a separate 8 VDC bus and draw only 0.2 A, allowing the use of a low-power control supply. Protective thresholds include an undervoltage trip at 90 VDC during normal operation and power-up, as well as an overvoltage trip at 430 VDC. An overtemperature latch activates at 118 °C to stop operation when the internal temperature reaches its protective limit.
