Place to aggregate motor information, mostly as it relates to microscopes

2018-05-28: creating page to aggregate industry pinout information and mcmaster recommendations.

Indexer connector (single)

BBB

mcmaster goal: come up with a standard connector to put on BBB cape

Goals:

  • Requirement: fit 6 connectors on reasonable size BBB cape
  • Use an existing standard
  • COTS cables, or at least easily
  • Shielded
  • Durable

Main candidates:

  • DB9
    • Durable connector
    • COTS super available
    • Shielded
    • Breakout boards readily available
    • No insustry standard pinout
    • I thought Gecko, but that's actually for the motors
  • DB25
    • Industry standard connector
    • Single and multi versions
    • However, too large
  • Combicon style connector
    • Quick to make
    • Can use shielded cables
    • Can't buy whole cable, or at least will be expensive
    • Wires can stress and fall off
    • Used on Gecko and some others, although not consistently

DB25 (step/direction)

Compumotor oem650 oem650 db25.png

Above: Compumotor OEM650 pinout

Pmc vs pmc vs db25.png

Above: PMC VS Drive pinout

This seems to have been a de facto standard for some years. I've observed it on Compumotor, PMC, and other drivers.

mcmaster: IMHO this is too bulky to use in modern applications, although I do have several legacy drivers using it


IDC 5x2 (step/direction)

Ims mdm ims idc.png

Used on some MDrive17 motors

mcmaster: of particular interest to me since I try to use these motors by default.



Indexer connector (multi)

Gecko DB25 (multi-axis indexer)

Gecko g540 g540 db25.png

Above: G540 indexer connection

The G320X servo driver uses post mounted Phoenix contact type connectors.


Motor connector (power + data)

M12 connector (power + CAN)

M12/M23 seems to be common on modern stepper motors. The MDrive manual for example cites it was done to reach IP65 enclosure rating:

The MDrive17Plus2-65 Motion Control adds protection against the ingress of fluids and dust to the MDrive17Plus2 by changing the motor-drive enclosure to meet IP65 specifications. With this change the connector configuration changes to industry standard M12/M23 circular connectors.

  • A-coding: actuator-sensor plug connections for DeviceNet, IO link and Profibus
    • DeviceNet is used my mcmaster MFCs
  • B-coding: Fieldbus connections for Profibus and Interbus
  • D-coding: Industrial Ethernet, Profinet, Ethernet/IP and EtherCat
  • S-coding: Motor, Frequency-convertors, motor operated switches, PSUs for Power, 620V, 12A
  • T-coding: Fieldbus comp, passive distribution boxes, motors, PSUs for Power, 63V, 12A
