AKT2G-SM-L50-000 and AKT2G-SM-L15-000 EtherCAT stepper drives allow you to control Stepper motors up to 5 Amp (6.5 with fan cartridge AKT2G-AC-FAN-001) with a PDMM or PCMM controller. The same function blocks used with servo motors are used in the KAS IDE development software, making it seamless to switch an axis from a servo to a stepper drive. Both slices have optional encoder inputs. Stepper motors are run open loop regardless, but can verify position commanded with an encoder.

This article provides a simple way to drive a stepper control by PCMM and AKD

A topic from the KAS Online Help which discusses the support of AKD-SM-Lxx stepper slices by KAS.

KAS Support of AKT-SM-Lxx Stepper Slices

This raw video shows one way to integrate a stepper motor control into a KAS EtherCAT Network.  It is done by integrating a P6000 stepper driver into a KAS EtherCAT Network via  an EBUS  EL2521 Pulse output slice module.  The  .kas  project file is attached.

 

Is a 30:1 inertia ratio high for a stepper motor?

I'm looking for a step motor in a NEMA 17 or smaller package with at least 10 in-oz torque at 100 RPM, capable of operating in a 100°C environment.

Can or has Kollmorgen ever done something similar to this?

A few simple steps to work the Beckhoff terminal EL7047 with KAS

Superior Electric manufactured an 8 pin integral connector for the AC Synchronous SS Series motors.

The connections are to B, F & G, with B being the center tap or Neutral connection.
