Checking the Z Axis Dynamics
Measurement Setup
The positioning time for the Z-axis is 21 +/-1 ms for the C&P12 head.
► Position the gantries so that the Z axis moves in a free space.
SITEST
► Select C&P heads ==> Select head ==> Axis functions
==> Select the Z axis ==> Select the permanent axis run, edit the values in digits and accept. Target
position = 685 digits and Position mode = absolute.
Axis control of Z axis
The Z axis is driven via a DC servo motor. Activation is
via a control signal (second control signal = 0) from the
processor of the A364 I
target "W"
and I
target "U"
= 0. The
intermediate circuit voltage is approx. 60V.

6. Between the motor and the incremental encoder
there is a fixed mechanical connection.
7. Incremental encoder: transmits the exact position of
the axis (track signals).
8. Elastic mech. connection (belt) and light barrier
down, for fast recognition of the lower position.
The servo board controls the DC motor directly.
NOTICE
The measurement procedure follows the same preparations and procedures as for the star ax-
is.

Axis control of DP axis
The DP axis is driven via a DC servo motor. Activation is
via a control signal (second control signal = 0) from the
processor of the A364 I
target "W"
and I
target "U"
= 0. The
intermediate circuit voltage is approx. 60V. Via a stepping
motor, the DP axis is coupled to the glass of the segment.
The DP axis positions the segment and is then decoupled
via the stepping motor.
