Rotor Control Tool for LB Tube (VCT)

Overview

Rotor Control Tool for LB Tube (VCT) was designed to start or stop (and coasting) X-ray Tube rotor manually on VCT 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}[1] rotor_ctrl –start Enter

And confirm that the following message is displayed.

Rotor started successfully.

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

Rotor is already rotated.

2 Deceleration to Low Speed (this option is available from 12HW14.6 SP2.3, 13HW31.8 SP2.1 and 16HW36.4 SP2.1 software)

Type the following command.

This command can’t use for rotor start, only for deceleration from High speed to Low speed.

{ctuser@bay} [1] rotor_ctrl -low Enter

And confirm that the following message is displayed.

Rotor decelerated to low speed successfully.

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

Rotor is already at low speed.

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

3 Stop rotor (or coasting).

Type the following command.

{ctuser@bay}[2] rotor_ctrl –stop Enter

And confirm that the following message is displayed.

Rotor stopped successfully.

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

Rotor is already stopped (or 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}[3] rotor_ctrl –stop <enter>
Attached to service service_sw_001..
Scanner resource is busy.
{ctuser@bay}[4]

        

(in case of 12HW14.6 SP2.3, 13HW31.8 SP2.1 and 16HW36.4 SP2.1 or later software) The following message is displayed to confirm tube temperature.

“This action will stop the tube rotor. Do not proceed if the TubeCare indicator is in the Green zone. Continue to stop rotor? (Yes/Quit)”

Enter “Yes” to proceed after tube temperature confirmation.

4 Show Tube temperature (track temp.)

Type the following command.

{ctuser@bay}[1] rotor_ctrl -temp Enter

Tube Temperature: 453.4

5 Show rotor status

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


{ctuser@bay}[1] rotor_ctrl -status <Enter>
Attached to service service_sw_001..

Successful
Current tube rotor state: Coasting or Stop
{ctuser@bay}[2]

        

The following shows the list of status.

  • Low speed (Low)

  • High Speed (High)

  • Accelerating to High:

  • High to Low: Decelerating to Low speed

  • Braking to Coasting (Braking)

  • Coasting or Stop

6 Help how to use.

Type the following command. Command usage help is displayed.


{ctuser@bay}[5] rotor_ctrl –help <enter>
-start:     Accelerate rotor.
-stop:      Decelerate rotor and coasting.
-low:       Decelerate rotor to low speed.
