SINAMICS G110M Operating Instructions
170 Operating Instructions, 04/2015, FW V4.7.3, A5E31298649B AD
Under the following conditions, the inverter switches from the main setpoint to other
setpoints:
● When the technology controller is active and appropriately interconnected, its output
specifies the motor speed.
● When jogging is active.
● When controlling from an operator panel or the STARTER PC tool.
Analog input as setpoint source
Interconnecting an analog input
If you have selected a pre-assignment without a function of the analog input, then you must
interconnect the parameter of the main setpoint with an analog input.
Figure 8-8 Example: Analog input 0 as setpoint source
Table 8- 1 Setting with analog input 0 as setpoint source
p1070 = 755[0]
Interconnect the main setpoint with analog input 0
p1075 = 755[0]
Interconnect the additional setpoint with analog input 0
You must adapt the analog input to the connected signal, e.g. ± 10 V or 4 … 20 mA. You will
find additional information in the section: Analog inputs (Page 120).
Specifying the motor speed via the fieldbus
If you enter the setpoint via a fieldbus, you must connect the converter to a higher-level
control. For further information, see Section Configure fieldbus (Page 125).
