In the following we show to you how to use ctrlX DRIVE under a Schneider control (using sercos).

Versions used

All the functions and screen shots are based on:

  • ctrlX DRIVE Engineering version 01V18
  • Runtime / Firmware version of drive AXS-V0308

Prerequisites

A connection to the ctrlX DRIVE has been successfully established, the device is correctly wired and 24 V are successfully put on. As well the engineering tool ctrlX DRIVE Engineering has been started.

1. Configure parameters of Schneider control

The Schneider control needs to be set correctly as following:

2. Parameterize ctrlX DRIVE

The parameterization of the ctrlX DRIVE should be according to the following guidelines, using

  • 0,001°             or   0,001 mm
  • 0,001 °/s         or   0,001 mm/s
  • 0,001 rad/s2     or   0,001 mm/s2

as resolution. Mind that you have to correct the travel range, gear ratio and feed constant according to your mechanics and needs.

Rotatory axis modulo

On the Schneider control

  • the correct gear ratio needs to be entered
  • the translatory setting must be “False”
  • the maximum travel range needs to be set to “0.0”
  • the modulo setting must be “True”
  • the modulo value and feed constant needs to be set to “360.0”

Rotatory axis absolute

On the Schneider control

  • the correct gear ratio needs to be entered
  • the translatory setting must be “False”
  • the maximum travel range and feed constant needs to be set to intended travel range value e.g. “360.0”
  • the modulo setting must be “False”
  • the modulo value needs to be set to “0.0”

Linear axis modulo

On the Schneider control

  • the correct gear ratio needs to be entered
  • the translatory setting must be “True”
  • the maximum travel range needs to be set to “0.0”
  • the modulo setting must be “True”
  • the modulo value needs to be set to intended value in here e.g. “127.0”
  • the feed constant needs to be set to intended value e.g. “508.0”

Linear axis absolute

On the Schneider control

  • the correct gear ratio needs to be entered
  • the translatory setting must be “True”
  • the maximum travel range needs to be set to intended value in here e.g. “400.0”
  • the modulo setting must be “False”
  • the modulo value needs to be set to “0.0”
  • the feed constant needs to be set to intended value e.g. “320.0”
