Product Description:

The DSM130 is a digital servo amplifier produced by Kollmorgen as part of the DSA SERCOS Drives series. Designed for closed-loop motion axes, the unit modulates bus power into three-phase motor current so that servo motors follow position, velocity, or torque commands issued by a SERCOS controller. In industrial automation, it serves as the interface between the motion controller and the motor, converting control-level setpoints into drive signals for packaging machines, material-handling gantries, and precision machining centers.

Key electrical parameters describe how the drive interfaces with both the controller and the DC link. It delivers a continuous output power of 3.0 kW while providing momentary acceleration current up to 30 A. Energy is buffered by a DC-bus capacitance of 2730 µF, and the link can absorb 97 J of regenerated energy before shunting. Velocity commands are accepted on an analog channel that spans ±10 V, and the closed-loop regulator tracks those references with a bandwidth of 400 Hz. One analog monitor output is available for diagnostics, while four selectable digital inputs and two selectable digital outputs handle discrete machine signals. For high-resolution synchronization, the master-encoder port and the step-direction interface both operate at 1 MHz. Under steady load, the drive supplies 15 A of continuous motor current.

The input side is rated for a continuous mains draw of 28 A. Regenerative energy is dissipated by an internal resistor that handles up to 50 W continuously, and a separate path can absorb bursts reaching 4.5 kW to keep the bus voltage within limits. This arrangement helps manage both sustained braking energy and short peak events. The housing weighs 6.48 kg, allowing panel installation without imposing significant mechanical load while still accommodating the integrated I/O and power electronics.
