5.2.4 C&P20 Axis Control
Service Manual SIPLACE X Series 299
Signal Example with the Vnom. Output
The star axis dynamics are checked in the permanent star step mode. A motor phase current is emitted
at the Vnominal output of the axis test box.(control signal 1). The uncommutated current setpoint signal
(signal 3) shows no increased friction values for the axis.
The positioning time for the star axis is 28.5 ms +/-0.5 ms C&P20 (from 31.01.05).
SITEST:
► Select C&P heads ==> Select head ==>Axis functions
==> Select the star axis ==> Star continuous run
==> Entry: waiting period 500 ms ==> Accept.
► Press the START button if required.
Star axis dynamic signals for C&P20
The signals from top to bottom:
▪ Star phase motor current Iu measured at Vnom out-
put
▪ Uncommutated current signal Vreg (or PIN at axis
adapter)
▪ Deviation of position
▪ End signal
NOTICE
C&P20
If these dynamics should be significantly slower or if the uncommutated current signal should
deviate considerably, check the star axis mechanics for damage or the servo amplifier/axis con-
troller (other boards connected to the star) for electrical damage.

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.

Velocity Commutation) or A 364
2. 1 control signal
3. LEDs on servo amplifier:
4. Servo amplifier
5. 3~ AC(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 3~ AC(DC) motor directly.

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.
