Product Description:

The CR10560 is a servo drive module produced by Kollmorgen within the CD Servostar CD Drives series. Intended for industrial automation, the unit conditions DC bus power and modulates current to a matched servomotor so motion axes receive tightly regulated torque and speed commands. It integrates into machine cabinets where analog velocity or torque references originate from a motion controller or PLC. This arrangement suits installations that use conventional analog control loops rather than digital network control.

It operates from a three-phase 230 VAC mains supply and internally generates a nominal bus of 325 VDC. Line loading remains moderate because the continuous input requirement is 13 A, which corresponds to an apparent power draw of 4.6 kVA at the rated supply. On the motor side, the drive can deliver a continuous armature current of 10 Arms, matching the product’s rated current, while short 500 ms bursts reach 20 Arms to cover acceleration peaks. Closed-loop regulation relies on analog command signals and rotor position data from a resolver, so no digital fieldbus is required. The three-phase output is pulse-width modulated, and the analog interface links the drive to the system controller.

Protective thresholds are built into the control section to disconnect the power stage when the DC link rises above 430 VDC or when heat sink temperature reaches 80 °C. The supply is also inhibited if the bus drops below 90 VDC, which helps prevent unstable operation during undervoltage conditions. Switching devices are clocked at 8 kHz to balance acoustic noise and current ripple, and internal heat dissipation reaches 132 W under full load. A dedicated 300 V logic rail keeps the control electronics active during transient mains variations. Braking energy is directed into an external resistor with a minimum resistance of 20 Ω, allowing the drive to handle regenerated energy during deceleration.
