Axis control of Z axis
The Z axis DLM2 head is driven via a DC servo motor.
The C&P20 Z axis is driven via a 3~ AC drive. This acti-
vation is via two control signals phase from the VC3 con-
troller Itarget "W" and I-target "U". The intermediate
circuit voltage is approx. 24V.

Checking the Z Axis Dynamics
Measurement Setup
The positioning time for the Z axis is 30 ms +/-3 ms (6 segment head) and 24 +/-1 ms DLM2 (for the 12
segment head) for 685 digits. The positioning time Z-C&P20 for 15 mm (equal to the DLM2 path) is
20 ms in both directions. For a path of 0-10000 digits (10 mm), the positioning time should be 16.7 ms.
Position the gantries so that the Z axis is above the calibration component position.
SITEST:
► Select C&P heads ==> Select head ==> Axis functions
==> Select Z axis ==> Axis continuous run Select and edit values in digits and accept. Target posi-
tion = 10000 digits (10 mm); Positioning type = absolute.

Checking the DP Axis Dynamics
Measurement Setup
The SIPLACE service technician can use special software to start a continuous function run and can, for
example, check the positioning times of the individual DP drives in SITEST (service password).
SITEST:
► Select C&P heads ==> Select head ==> Axis functions
==> DP Select the axis ==> Select Axis continuous run and enter the values in 1/100° (start position
0 – target position 18000) position time = absolute
= Start
⇨ The value shown for each individual DP drive should be less than 300 ms at 180°.
Axis control of DP axis for a C&P20 segment
The DP axis of the DLM2 head is driven via a DC servo
motor. The DP axes of the C&P20 segments are posi-
tioned by a DP masterboard and an "on board" direct
control unit. The control system uses CAN Bus at the re-
spective head board. The intermediate circuit voltage is
approx. 24 V. There is no swiveling in or out of a turning
station due to the direct drive in the segment drive motor.
The MC transmits the activation commands via the ma-
chine CAN Bus to the head processor.
This activates via four DP tasks and the head CAN bus
system with activation commands, via the
▪ head adapter
▪ intermediate distributor,
▪ the collector rings of the E/D transformer at the moth-
erboard with the DP motor.
The DP motor control in the segment is handled at the DP
control board with the help of count pulse from the inte-
grated HALL incremental encoder.
NOTICE
No measuring points
There are no measurement points accessible on the C&P20 rotary drives.
