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
for an ambient temperature of 40 °C
S
for an ambient temperature of 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 switched 24 V outputs for axes 1 and 2 are protected by miniature fuses;
fuse type F1900 for axis 1 and F1901 for axis 2.
Value: 2.5 AF/250 V; 5x20 mm UL
