Product Description:
The P60660-SDN-001 is a stepper motor drive built by Kollmorgen and assigned to the P6000 Stepper Drives series. The unit conditions AC mains power and converts it into controlled current pulses for two-phase stepper motors, providing precise incremental positioning in assembly cells, pick-and-place stations, and indexing tables. It is designed to pair directly with Enhanced POWERPAC motors, creating a matched motion axis without additional tuning hardware. By regulating phase current rather than applying raw line voltage to the motor windings, it helps maintain accurate position control during repeated start-stop motion.
Its two-phase bipolar chopper circuit modulates coil energy at a carrier of 20 kHz, keeping motor torque smooth while reducing audible noise. This switching method also supports stable current regulation across a broad operating range during frequent acceleration and deceleration. The drive accepts a single-phase or three-phase input of 120/240 VAC and draws up to 6.0 A RMS from the mains, while internal power handling reaches 660 W before protective limits respond. On the output side, each motor phase can receive a continuous current of 5.7 A RMS, with instantaneous peaks reaching 8.0 A to support high-acceleration move profiles. Direction changes are recognized with command pulses as short as 50 µs, and a 100 mA, 30 VDC fault transistor provides status to the host controller. Three mating plug-in connectors are supplied so field wiring can be completed without special tools.
The aluminum housing measures 54 × 177 × 120.5 mm, allowing the drive to fit into narrow control panels alongside PLCs and contactors. The unit weighs 1.26 kg, which eases DIN rail or bulkhead installation and reduces mounting load inside compact enclosures. A micro-stepping generator can accept clock signals up to 2 MHz, so the motion controller can command very fine resolutions without aliasing. Current and power levels are protected by an internal 10 A fast-acting fuse that clears high-energy faults before semiconductor damage occurs.
