Kollmorgen launches the advanced P80630-SDN stepper drive

Kollmorgen has announced the new P80630-SDN stepper drive, saying customers can benefit from features such as smoothness, precision and torque across the full speed range in a significantly more compact package that enables smaller, lighter, more versatile machines.

The P80630-SDN stepper drive powers and controls stepper motors operating on 24 to 75 VDC with up to 5.5 Arms current per phase (7.8 Arms peak). It’s said to be an ideal solution for labellers, indexing tables, CNC machines, packaging systems, pumps and other single-or multi-axis systems requiring low-speed, point-to-point motion control for fixed loads.

Building on the success of previous Kollmorgen drives such as the 6410 and P70530, the new P80630-SDN drive delivers improved positional accuracy as demonstrated in laboratory tests using PMX series stepper motors. This compact, powerful new drive achieves 10% greater output current in a 60% smaller package that is up to 34 mm shorter in height than the 6410, depending on the model. Moreover, it reduces setup time by delivering smooth, precise performance at all speeds without the need for electronic damping control switches.

The P80630-SDN stepper drive supports conventional single-ended or differential step and direction interfaces (user-provided pulse train required) or CW/CCW command inputs. Dip-switch selectable settings include motor phase current, idle current reduction and step resolution up to 1/128 microstep, all with no programming required. Dedicated enable input and fault output provide control of the drive's power stage and error monitoring.

Additional models with new features are scheduled for release in the coming months. Selected drives will also include widely used fieldbus protocols for integration with industry-standard motion controllers. All drives in the series are CE, RoHS and REACH certified.
