7.5 Axis control C&P head axes
7.5.1 Overview Axis control Star-, Z- and DP-Axis
The closed-circuit control system for control of the
head axes consists of the following parts. Between
the head axes, some differences which will be
explain later in this chapter.
Axis board A364
Servo board (SDS/TBS)
Motor
Measurement system (incremental scale and
encoder (read unit)
Legend:
1. Axis board A364
2. Control signals I soll "W" and I soll "U"
3. Servo amplifier
4. LED‘s on Servo board:
Power supply ON
Servo enable, it the enable signal from the
axis board.
Display R.M.S. current limiter shorter than
2,5 s.
Error: Overvoltage, overcurrent,
overtemperature or nominal current
overshoot longer than 2.5 sec.
5. 3 Phase AC motor.
6. Between the motor and the incremental
encoder exist a fixed mechanical combination.
7. Incremental encoder: transmit the exact
position of the axis The track signals are the
only feedback signals for the axes.
The servo board controls the motor directly.

7.5.1.1 Overview positioning time 12 segment C&P head
7.5.2 Track signals head axes
The track signals play a greater role with the new drive concept for SIPLACE machines. They are
responsible for the exact and precise positioning of the axes and are used as the only response of the
closed-circuit control system so that the track signals have an important influence on dynamics of the
axes.
