7.3.1 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 7-8 Example: Analog input 0 as setpoint source
Table 7- 7 Setting with analog input 0 as setpoint source
Parameter Remark
p1070 = 755[0] Main setpoint
Interconnects the main setpoint with analog input 0
p1075 = 755[0] Additional setpoint
Interconnects 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.
7.3.2 Specifying the setpoint via the fieldbus
Interconnecting the fieldbus with the main setpoint
Figure 7-9 Fieldbus as setpoint source
Most standard telegrams receive the speed setpoint as a second process data PZD2.
Table 7- 8 Setting the fieldbus as setpoint source
Parameter Remark
p1070 = 2050[1] Main setpoint
Interconnects the main setpoint with process data PZD2 from the fieldbus.
p1075 = 2050[1] Additional setpoint
Interconnects the additional setpoint with process data PZD2 from the fieldbus.
