Drive
X1
The process variable x1 is connected to analog input
AE1, the command variable x2 is linked to analog
input AE2.
Signal range of both inputs is 0 to 20 mA as well; it
can be reconfigured to 4 to 20 mA (S37 = 1).
The alarm circuit monitors the process ratio factor xv
for max./min. deviations.
For adjustment of the ratio factor range see page 38.
Please refer to the remarks on page 108 !
Setting of configuring switches: S1 = 7, S10 = -1, S22 = 1
