7.5.3.1.3 Example for dynamic with the control signal of the Vnom. output
The star axis dynamics are checked in the permanent star step. A motor phase current (control signal 1)
is emitted at the V nominal output of the axis test box. The uncommutated current setpoint signal
(signal 3) shows increased friction axis values.
The positioning time for the star axis is 43 +/-3 ms for the C&P12.

NOTE:
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.

7.5.4 Axis control 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
voltages is approx. 60V.

3. 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. DC motor.
6. Between the motor and the incremental
encoder exist a fixed mechanical combination.
7. Incremental encoder: Transmits the exact
position of the axis (track signals).
8. Elastic mech. Combination (Belt) and light
barrier below, for the fast recognition of the
lower position.
The servo board controls the DC motor directly.
