Dispensing Head Moves in Z-Axis
FmNT Command
A program command is issued to the
FmNT software.
PMAC Card
y
Receives FmNT command to move
Dispensing Head to a specific Z-axis
position.
y
Sends low-voltage direction and power
level output signals to the Z Servo
Amplifier.
y
Receives feedback from Z Motor Rotary
Encoder (velocity)
y
Calculates how much power should be
delivered to Z Servo Motor.
Main Interface PWA
y
Is an intermediate step as information is
communicated between the PMAC
Card and the XY Servo Interface PWA.
XY Servo Interface PWA
y
Relays PMAC signals to the Z Servo
Interface PWA.
Z Servo Interface PWA
y
Relays PMAC signals from the XY
Servo Interface PWA to the Z Servo
Amplifier.
Rotary Encoder
y
S
upplies velocity and acceleration
information to the PMAC.
Z Servo Motor
y
Receives power from the Z Servo
Amplifier.
y
Turns the drive gear (pinion) that moves
the Dispensing Head in the Z-axis
Computer
Hall Sensor
y
Senses Z Servo Motor direction and
reports it to the Z Servo Amplifier.
Dispensing Head
Z Servo Amplifier
y
Receives PMAC low-voltage motor direction and power
signals through the Z Servo Interface PWA
y
Amplifies PMAC signals into high power level to move the Z
Servo Motor.
y
Receives and interprets Hall Sensor feedback that indicates
direction motor is turning.
y
Regulates power to motor windings to cause motor to move
in the desired direction.
