Changing the function of the analog input
1. Define the analog input type using parameter p0756 and the DIP switches on
the Control Unit for current or voltage input.
2. Specify the function of the analog input by interconnecting parameter p0755
with a connector input CI of your choice, for example as a speed setpoint.
Define the analog input
WARNING
Maximum voltage for analog input
The maximum voltage difference between the individual analog input connections and the
ground must not exceed 35 V. If the system is operated when the load resistor is switched
on (DIP switch set to "A"), the voltage between differential the individual analog inputs must
not exceed 10 V or the injected 80 mA current otherwise the input will be damaged.
CAUTION
Analog DIP switch and parameter settings
The selection of current (I) or voltage (V) input can be accomplished using the DIP switched
on the Control Unit. Parameter p0756 must also be modified to ensure that the p0756
reflects the settings of the DIP switch. If there is a difference between the two settings the
motor may run faster or slower than expected if the analog input is used as a setpoint
source.
The converter offers a set of DIP switches where the type of analog input can be selected.
This is shown in the following figure:

with DIP switches (Page 93).
