Dispensing Head Moves in X or Y-Axis
FmNT
A program command is issued to the FmNT
software.
PMAC Card
y Receives FmNT command to move
Dispensing Head to a specific XY position.
y Sends low-voltage direction and power level
output signals to the X and Y Servo Amplifiers.
y Receives feedback from:·
¾ X and Y Linear Encoders (position)
¾ X and Y Rotary Encoders (velocity)
y Calculates how much power should be
delivered to Servo Motors.
Main Interface PWA
y Is an intermediate step as relayed information
is communicated between the PMAC Card
and the XY Servo Interface PWA.
XY Servo Interface PWA
y Relays PMAC signals to the X and Y Servo
Amplifiers
X and Y Linear Encoders
y Supply Dispensing Head position
information on a constant basis to the
PMAC.
XY Servo Amplifiers
y Receive low-voltage motor direction and
power signals from the PMAC
y Amplify PMAC signals into high power level to
move the X and Y Servo Motors.
y Receive and interpret Hall Sensor feedback
that indicates direction motor is turning
y Regulates power to motor windings to cause
motor to move in the desired direction.
Rotary Encoders
y Supply velocity and acceleration
information to the PMAC.
XY Servo Motors
y Receive power from Servo Amplifiers.
y Turn the cable pulleys to move the
Dispensing Head in the X and Y-axes.
Computer
Servo Interconnect Cables
Hall Sensors
y Sense X and Y Servo Motor direction and
report it to the X and Y Servo Amplifiers.
