Instructions to replace a picomotor controller


Case 1: If the picomotor controller is a slave controller

  1. Download and install picomotor software on a Windows machine (preferably a laptop). There are plenty of
  2. Get USB to micro-USB cable (there's one in B244 in the pico motor box)
  3. Connect master controller or any functional controller of the stack with the USB cable to the windows machine.
  4. Open the pico motor controller software. You should see an image as in [ Img A ]. Motor controllers are numbered by the scheme"Controllername (1,2,3,...)". The actual name of the controller is its network controller name. Note down the name you would like to give the controller and the number in brackets as given by the main controller.  A broken controller might not appear in the list so you might have to deduct the right name and number from the other controllers or naming scheme in EPICS.
  5. Disconnect the master controller from the windows machine and connect the replacement controller to the windows machine.
  6. Change the number of the controller to the number of the broken controller. You can do that by right-clicking on the controller in the left-hand-sided list.
  7. Go to  Setup→ Ethernet and change the network name to the name of the broken controller
  8. Disconnect the broken controller from the stack and connect the replacement in the same location and with same cabling. Especially the data cables should be in the same order.
  9. Uninstall the broken controller and install the replacement in the same place.

Picomotor configuration

From facet elog, Spencer writes...

At FACET, we had 26 picomotor controllers supporting up to 104 picomotors, distributed in 11
groups. A single group had up to 3 picomotors in a stack.
Ziga deployed new picomotor controller software which allows for up to 9 controllers in a stack.
Now we are down to 4 groups of picomotors:


MOC-LI20-MC06: Laser room picomotors. Stack of 6 to support up to 24 motors.
MOC-LI20-MC07: Laser transport B1, B2, B3. Stack of 2 supports 6 motors.
MOC-LI20-MC08: In-vacuum tunnel picomotors including B4, B5, B6. Stack of 9 supports up to
36 motors.
MOC-LI20-MC09: In-air tunnel picomotors. Stack of 9 supports up to 36 motors.
