It can control 2 axes of motion while monitoring their actual positions with the built in incremental encoder interface. The board has Motorola 68000 processor which can be programmed to execute wide variety of motion commands. Two sync lines are available to synchronize moves to external events and there is an auxiliary line for each axis to allow the control of external events. The start of wire movement is initiated by V102 Event Link Delay Module. Motion signals generated by the motor controller board, besides being used for motor control, are used as external scan trigger signals to MADC module.
All signals generated by or going to motor controller board go through transition module.
The transition module mode of operation is determined by the state of motor controller X and Y auxiliary lines. The purpose of this mode of operation is to take background measurements. On receiving command to allow the movement of particular axis, it should set desired parameters of the motion and load the program into the motor controller board. When that happens, the board should generate pulses for the motor to start moving wire to the predefined position on the other side of the beam and to stop when it reaches it. Then it should wait that sync line goes high again before issuing pulses to the motor to move the wire back to its starting position.
