The analog valve actual value inputs are differential with 100 kΩ input
resistance.
The current ratings of the 24 V outputs on the servo solenoid value are
S
at ambient temperature 40 °C
S
at ambient temperature 55 °C
for the mean current value with a load cycle of 10 s duration.
The temperature corner points may be interpolated linearly.
The short-term current rating of the servo solenoid valve outputs is 3.0 A (200
ms).
In the event of overload, fuse F1900 or F1901 on the HLA closed-loop control
plug-in module (for position, see Fig. 5-2) will blow.
The 24 V outputs switched for axes 1 and 2 are protected by miniature fuses,
i.e. fuse type F1900 for axis 1 and F1901 for axis 2.
