8.4 MOTOR INTERFACE PCB (MOTIF)
NOTE: REFER TO PCB AND CABLE LOCATION SECTION FOR BOARD DIAGRAMS.
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 (660)
P7 Y-axis encoder, Z, home, and overheat (670)
P8 Z-axis encoder, Z, home, and overheat (680)
P9 A-axis encoder, Z, home, and overheat (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)
P19 Address buss
P20 Spindle encoder inputs (1000)
P21 A-to-D input for spindle temperature (1020)
P22 A-to-D input for spindle load monitor (730B)
P24 Home switch inputs X, Y, Z (990)
8.5 MOTOR CONTROLLER (MOCON) BRUSHLESS
NOTE: REFER TO PCB AND CABLE LOCATION SECTION FOR BOARD DIAGRAMS.
The brushless machining centers are equipped with a microprocessor based brushless motor controller board (MOCON)that
replaces the motor interface in the brush type controls. It runs in parallel with the main processor, receiving servo commands
and closing the servo loop around the servo motors.
In addition to controlling the servos and detecting servo faults, the motor controller board, (MOCON), is also in charge of
processing discrete inputs, driving the I/O board relays, commanding the spindle and processing the jog handle input.
Another significant feature is that it controls 6 axes, so there is no need for an additional board for a 5 axis machine.
P1 Data Bus
P2 X amplifier control and fault sensing (610)
P3 Y amplifier control and fault sensing (620)
P4 Z amplifier control and fault sensing (630)
P5 A amplifier control and fault sensing (640)
P32 B amplifier control and fault sensing (640B)
P33 C amplifier control and fault sensing (640C)
P6 X encoder input (660)
