MOTOR I NTERFACE PCB (MOTIF)
The Motor Interface PCB provides all of the interfaces to motors and discrete inputs and outputs. It contains a
single pot R54 to adjust the output of the D-A converter. The MOTIF PCB connectors are:
P1 Data buss
P2 X drive control and overcurrent sense (610)
P3 Y drive control and overcurrent sense (620)
P4 Z drive control and overcurrent sense (630)
P5 A drive control and overcurrent sense (640)
P6 X-axis encoder, Z, home, and overheat signeal (660)
P7 Y-axis encoder, Z, home, and overheat signal (670)
P8 Z-axis encoder, Z, home, and overheat signal (680)
P9 A-axis encoder, Z, home, and overheat siganl (690)
P10 32 discrete inputs (550)
P11 Relay drives 1 to 8 (510)
P12 Relay drives 9 to 16 (520)
P13 Relay drives 17 to 24 (530)
P14 Relay drives 25 to 32 (540)
P15 Power connector (+5,+12+)
P16 D-to-A output and -12V DC (720)
P17 A-to-D inputs for DC buss voltage (980)
P18 Jog Crank input and aux 1,2 (750)
