2.3.3 Control inputs
The inputs are coupled optically.
For selecting the inputs there are two possibilities (figure 2.4):
a) By means of a potential-free contact, the higher
control links the terminal of the control voltage
"U0" to the corresponding input.
b) The higher control feeds an external voltage of
+24V to the input. The terminal "GND" serves as
reference potential.
Figure 2.4 Triggering possibilities
Control inputs:
"GND" Reference potential
"U0"
Control voltage
DC output of approx. 21V for activating the inputs.
"RF"
Controller release
The input "RF" has to be triggered during running.
"V1"
Positioning speed
"V2"
Intermediate speed
"V3"
Travel speed
"VZ"
Readjustment speed
"ZE1"
Additional speed V_ZE1
"ZE2"
Additional speed V_ZE2
"ZE3"
Additional speed V_ZE3
These inputs are provided for triggering various functions in the controller. The adjustment is
effected in the menu /INTERFACES. The
additional speeds V_ZE1, V_ZE2
and
V_ZE3
of the
same name are selected by the manufacturer.
Preferably these speeds are to be used for inspection run and restoring control.

If the controller is connected up as suggested in circuits A8 (in the Appendix), the motor will run
(with works setting) anti-clockwise when the "RV1" input is activated and clockwise when the
"RV2" input is activated (viewed from the drive end of the shaft).
