Page History
This page describes various fields found within the motor-expert-screen. This screen is the user friendly interface for quickly changing motor parameters. Keep in mind that one must have permissions to access a hutch machine if you would like to edit. View permissions are wider (including e.g. psbuild-machines).
To access a live(modifiable) motor-expert-screen, there are two ways :
- In a terminal, ssh into the appropriate hutch machine and run the command motor-expert-screen <PV name> (i.e. motor-expert-screen XPP:USR:MMS:17).
- In a terminal, ssh into the appropriate hutch machine and start a hutch python session (i.e. <hutch name>3).
- Type x.[tab] to bring up all user motors available in that session. Then x.<motor name>.screen().

| EPICS PV | Field | ... | Description |
|---|---|---|---|
| .FREV | Full Steps | Modifiable | Specify the number of stepper motor steps required for a full rotation of the drive shaft. This value is specific to the motor. IMS Motors typically have 200. |
| .MS | Microsteps | Modifiable | Specify the number of microsteps in between each individual motor step. This value is specific to the motor. IMS Motors typically have 256. |
| .SREV | MS/Revolution | Modifiable | Specify the number of microsteps per full rotation of the drive shaft. This value is Full Steps * Microsteps. IMS Motors typically have 51200. |
| .UREV | EGU/Rev | Modifiable | EGU's Per Revolution. |

| .BDST | Backlash Dist | Modifiable | This field specifies an 'overshoot direction and magnitude.' For example, when the field is set to some positive x value, when the motor is instructed to move in a positive direction, it will overshoot the target position by x before returning to the actual target position. |
