Kollmorgen P70360-SDN

Product Introduction
The P70360-SDN is a high-performance digital microstepping drive from Kollmorgen, designed as the standard (non-indexer) variant of the P7000 series. The “SDN” designation indicates a drive configured for step/direction command mode with default GPI assignments including Jog+, Jog-, EOT+, EOT-, and Fault Reset. Unlike the PNN variant, the SDN does not include built-in motion profiling or Move Select inputs

Functional Features

  • Step/Direction Command Mode: Optimized for external controller-driven motion with high-frequency step pulse reception.
  • Anti-Resonance Control: Eliminates mid-range resonance and prevents loss of synchronism at critical velocities.
  • Dynamic Smoothing: 2nd-order low-pass filter reduces jerk and mechanical shock during motion transitions.
  • Stall Detection: Continuous position monitoring with fault output when deviation exceeds two full steps.
  • Configurable General Purpose Inputs: 9 optically isolated inputs configurable as sinking or sourcing, with global digital debouncing.
  • P7000Tools Compatibility: Full configuration support via Windows-based software for motor characterization, I/O mapping, and diagnostics.

Application Scenarios

  • External Controller Integration: Applications where a PLC, motion controller, or PC generates step/direction commands.
  • Conveyor Systems: Precise web transport and indexing in packaging and converting machinery.
  • Rotary Tables: High-resolution angular positioning for CNC and inspection equipment.
  • Linear Stages: Precision linear motion in semiconductor handling and metrology.
  • Automated Dispensing: Controlled dispensing and dosing in pharmaceutical and food processing.

Performance Parameters

  • Microstepping Resolution: Up to 50,000 steps per revolution.
  • Resonance Suppression: Digital anti-resonance prevents mid-range velocity instability.
  • Stall Detection Accuracy: Fault triggered when position deviation exceeds two full steps.
  • Input Frequency: Maximum 2 MHz step input with 250 ns minimum ON/OFF times.

Material Composition
Aluminum chassis with integrated heat sink fins, high-reliability power MOSFETs, optically isolated I/O circuits, and surface-mount DSP components on multi-layer PCB assemblies.

Structural Features

  • Cold-Plate Mounting: 8×32 or M4 screw mounting with left-side heat sink orientation.
  • 26-Pin D-Sub Connector (J4): Command I/O including step, direction, enable, GPIs, and fault output.
  • RJ12 Serial Port (J5): RS-232 interface for P7000Tools configuration.
  • 1 inch Clearance: Minimum spacing required on all sides for convection cooling.

Working Principle
The P70360-SDN receives step and direction pulses from an external controller through the J4 connector. The internal DSP applies dynamic smoothing to the command sequence, then generates PWM signals to drive the stepper motor windings with microstepping precision. The drive monitors shaft position continuously and triggers a fault if a stall condition is detected. Default GPI assignments (Jog+, Jog-, EOT+, EOT-, Fault Reset) provide basic operational control without requiring external programming. Configuration is performed via RS-232 using P7000Tools software.
