C&P6 - star axis diagram
Star axis travel curves for C&P6
1. Current target value: 2 V/Div
2. Position deviation: 500 mV/Div
3. End signal
Time basis: 10ms/Div
Step: 60000 digits = 60 degrees
NOTICE
Dynamics
If the dynamics are significantly slower, check the friction blocks on the star and the installation
of the star in the drive's magnetic neutral position.

Axis Control of Z Axis
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
VC3 controller I -target "W" and I -target "U" = 0. The in-
termediate circuit voltage is approx. 60 V.
1. Axis controller board A363 with VC3 controller (VC =
Velocity Commutation) or A 364
2. 1 control signal
3. LEDs on servo amplifier:
4. Servo amplifier
5. DC motor.
6. Between the motor and the incremental encoder
there is a fixed mechanical connection.
7. Read unit: 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.

Checking the Z Axis Dynamics
Measurement Setup
► Position the gantries so that the Z axis moves in a free space.
SITEST
► Select C&P heads ==> Select head ==> Axis functions
==> Select Z axis ==> Axis continuous run and edit the values in digits and accept. Target position
= 685; Positioning type = absolute.

NOTICE
Same measurement procedure
The measurement procedure follows the same preparations and procedures as for the star ax-
is.
