Interface
The motion controller is connected to the detector EDC board’s collimator ID EEPROM interface.
The EDC board firmware emulates an EEPROM function in which a register address is used as
control and status register for the motion control function. This enables the acquisition PC to
control this motion.
Trouble-shooting and Manual Control of Motions
To trouble-shoot the box motion controller, you connect a PC to the RS232 interface of the EDC
board. For instructions on connecting the PC and using the HyperTerminal program, see Chapter 5
Diagnostics
, the section
EDC Module Diagnostics
.
To read the motion controller’s status register, issue the command:
-> eeprom 1 0x240
The significance of the response is as follows:
x1
Line source compartment is in scan position (OUT)
x2
Line source compartment is in mid position
x4
Line source compartment is in park position (IN)
x8
Error: illegal switch combination
1x
Line source compartment moving towards scan position (OUT)
2x
Line source compartment moving towards mid position
4x
Line source compartment moving towards park position (IN)
8x
Error: Motion of line source compartment stopped due to an error (switch error or motor
power off caused by e.g. collision or activation of E-Stop)
0x
Line source compartment stopped without error.
You can control the motions of the line source compartment manually by writing the motion
controller’s control register. To write the motion controller’s control register, issue the command:
-> eeprom 1 0x240 <cmd>
where
<cmd>
is one of the following:
0x10
Move to scan position (OUT)
0x20
Move to mid position
0x40
Move to park position (IN)
0x00
Stop motion in progress.
DC-DC power converters
One DC-DC converter is powered from 55 V from the gantry AC mains power supply and
continuously provides 24 V for the box motion controller and the line source motion controller
residing inside the line source compartment.
The other DC-DC converter is powered from E-Stop controlled 48 V provided by the AC option
power supply in the gantry. This DC-DC converter provides E-Stop controlled 24 V for the motor
moving the line source compartment, the line source and the shutter.
