Rotor Control Tool with LB Tube - Command

Overview

Rotor Control Tool for LB Tube was designed to start or stop (and coasting) X-ray Tube rotor manually on LB Tube system. It’s a command tool and executed from command window. When rotor started using this tool, 20min. timer for deceleration rotor to low speed does not work. This tool requires Scanner resource for stopping rotor, but doesn’t require for starting rotor.

1 Start rotor.

This tool accelerates rotor from Stop to high speed or low speed to high speed.

Type the following command.

{ctuser@bay} rotor_ctrl –start Enter

And confirm that the following message is displayed.

  • Successfully
  • Rotor statrs roating. Wait for the second resopnse...
  • Rotor became rotated.
  • Rotor started successfully.

If the rotor already started, the following message is displayed.

  • Successful
  • Rotor is already rotated.
  • Rotor statred successfully.

3 Deceleration to Low Speed

Type the following command.

This command is only for rotor decelerating from High speed to Low speed.

{ctuser@bay} rotor_ctrl -low Enter

And confirm that the following message is displayed.

  • Successfully
  • Rotor starts deceleration to low speed.
  • Rotor low: Rotor decelerated to low speed successfully.

If the rotor is already at low speed, the following message is displayed.

  • Successful
  • Rotor is already at low speed.
  • Rotor low ：Rotor became low speed successfully.

This option is not available from stop to low speed acceleration.

4 Stop rotor (or coasting).

Type the following command.

{ctuser@bay} rotor_ctrl –stop Enter

The following message is displayed.

  • successfully
  • Rotor starts stopping. Waiting for the second response...
  • Rotor became stopped (coasting).
  • Rotor stop: Rotor stopped successfully.

If the rotor already stopped, the following message is displayed.

Current Tube rotor state: Coasting

If another SV Tool occupies Scanner resource, the following message is displayed and command is terminated. In this case, close the tool and execute the command again.

{ctuser@bay} rotor_ctrl –stop Enter

Scanner resource is busy.

5 Show Tube temperature (track temp.)

Type the following command.

{ctuser@bay} rotor_ctrl –temp Enter

Tube Temperature: 118.0

This command can show the tube temperature.

6 Show rotor status

Type the following command. Characters with underline show the rotor status.

{ctuser@bay} rotor_ctrl –status Enter

Current tube rotor state: Stop

The rotor status shows as follows:

  • Low (Low speed)
  • High (High speed)
  • High to Low (Decelerating to Low speed)
  • Coasting (Braking to Coasting)
  • Coasting or Stop

7 Help to use.

Type the following command. Command usage help is displayed.

{ctuser@bay} rotor_ctrl –help Enter

  • -start: Accelerate rotor.
  • -stop: Decelerate rotor and coasting.
  • -low: Decelerate rotor to low speed.
  • -status: Show the rotor status.
  • -temp: Show X-Ray tube track temperature (def. C).
  • -help, -h: Print this help screen.
