RICH 2015 Testbeam Translation Stages Control

Devices manuals:

  • Translation stages: MICOS MT-85, manual

  • Motion controller: NI PCI-7330, manual

  • Stepper motor drive: NI MID-7604, manual

The most important specification: 1000 steps = 1 mm

A picture of the stages:

Initialization

Start up NI MAX

  • Expand Devices and Interfaces
  • Expand NI Motion Devices
  • Expand PCI-7330 (1)
  • Expand Default xxxx Settings
    • Select Axis 1 and press the Initialize button (see image below)
    • Select Axis 2 and press the Initialize button (see image below)

Usage

How to control the stages?

On NI MAX

  • Expand Devices and Interfaces
  • Expand NI Motion Devices
  • Expand PCI-7330 (1)
  • Expand Interactive
    • Select 1-D Interactive in order to move one axis (see image below)
    • Select 2-D Interactive in order to move the two axes together (see image below)

  • Fill all the important parameters (red boxes)
    • Choose the axis/axes:
      • axis 1 controls the Jura Side ECs and points to Jura
      • axis 2 controls the Saleve Side ECs and points to Saleve
    • Choose the operation mode: absolute position (w.r.t. the origin, see How to find the reference frame?) vs relative position
    • Set a velocity: DO NOT exceed 1000 steps/s
    • Set a target position, remember 1000 steps = 1 mm

  • The current positions and speeds of the stages are monitored by the Current Trajectory Data section (blue box)

  • SUGGESTION: move the two axis separately especially if the axes are near their limits (if one axis reaches one of its limits during a movement, both the axes stop!)

  • WARNING: the Reset Position button (purple box) changes the position of the origin of the axis, please DO NOT press it

  • Press Apply, then press Start

How to find the reference frame?

On NI MAX

  • Move the axes to their negative limits

  • Insert the following coordinates using the Reset Position button (see here)
    • axis 1: 57670 steps
    • axis 2: 58130 steps

  • The following image shows the geometrical position of the two stages at the end of this procedure, remember 1000 steps = 1 mm

  • The coordinates of the nominal position are:
    • axis 1: 65500 steps
    • axis 2: 65500 steps

LEDs status

  • Good: axes away from their limits

WP_20150717_009_mod.jpg

  • Good: axes at one of their limits

  • Bad: axes inhibited, fix it repeating the inizialization (see here)
