Principle of Operation
Axis positioning commands are input to the
CNC;
manually using the jog
functions or hand wheels; by
CNC
commands in the
MDI
,
TAPE
, and
MEM-
ORY
Modes; or through a
DNC
link.
All axis positioning commands are read by the
CNC
and sent to the posi-
tion control software for processing. The commanded movement (dis-
tance) is calculated by the position calculating circuit and entered into an
error counter. The error counter value is compared to the feed back signal
from the motor pulse coder. The position control circuit then issues a com-
mand to reduce the difference between the value in the error register and
feed back signal to zero.
The “error” between command and feedback is converted into a signal
and amplified by an
AC
servo amplifier rotating the motor. The speed feed
back signal is converted to F/V and fed to the amplifier to change the turn-
on angle and control the axis speed.
Rotation of the servo motor is transferred into linear axis movement via
the ball screw, which is coupled to the servo motor. The ball screw is the
axi driving member and moves the axis component (saddle, table, or ram).
Each component is attached to the ball screw at the ball nut. During ball
screw rotation the ball nut and the axis component are moved along the
precision screw.
Each axis component is mounted to sliding members. The V55 uses LM
(Linear Motion) guides as the sliding members for all axes. Sliding mem-
bers maintain the axis component's geometry (squareness, height, paral-
lelism) related to other axis components and ensures that the axis travels
accurately along its coordinate plane.
