Communication with MCB and Collimator
DAC7554 is used to output 3 analog channels and its control accuracy is 12-bit. It shall be controlled by MCB
through SPI, in order to generate collimator-motor- target-position control signal. There are 3 motors in
collimator, which are IRIS motor, shutter width motor and shutter rotation motor. Therefore, DAC in CCB shall
support 3 independent channels. Meanwhile, CCB transmits 3 motors’ position feedback (analog signal) to MCB
directly. Through the PID adjustment, the motor driver can control the motor properly.
