Advanced Commissioning - Siemens SINAMICS G110M Operating Instructions Manual

Define the analog input
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.
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:
For further information on commissioning using the DIP switch, see
Commissioning with DIP switches (Page 104).
Figure 6-4
As previously mentioned, parameter p0756 can be modified to change the type of analog
input. The default settings for parameter p0756 and its default settings are given in the
following table.
