Analog Inputs (M3.5.2)
The analog inputs are very flexible to use. Parameters are functions/features that connect to the required analog
input terminals. The analog inputs are represented by the slot they exist on. Analog inputs 1 and 2 exist by default
on SlotA. For example, AI 1 Signal Selection (P3.5.2.1) would connect analog input 1 when set as AnIN SlotA.1.
NOTE:
The status of the analog inputs can be monitored in the Multimonitor (M2.1) view, or
in the I/O and Hardware (M5) menu.
The analog inputs settings are presented in the following table:
Table 32: Analog Inputs Settings.
Structure Parameter Unit Min Max Default ID Description
P3.5.2.1 AI1 Signal Sel AnIN SlotA.1 377 Defines the location of the signal to
be used as analog input 1.
P3.5.2.2 AI1 Filter Time s 0 300 1 378 Defines the time it takes to reach
63% of a step change in the analog
input signal defined by AI1 Signal
Sel (P3.5.2.1).
When this parameter is given a
value > 0, the function that filters
out disturbances from the incoming
analog signal is activated.
NOTE: Long filtering time makes
the regulation response slower.
P3.5.2.3 AI1 Signal Range 0-10V/
0-20 mA
2-10V/
4-20 mA
0-10V/
0-20 mA
379 Defines the signal range for the
analog input defined by AI1 Signal
Sel (P3.5.2.1). Ranges are as
follows:
0 = 0 to 10 Vdc/0 to 20 mA
1 = 2 to 10 Vdc 4 to 20 mA
NOTE: This setting can be
bypassed by using AI1 Custom Min
(P3.5.2.4) and AI1 Custom Max
(P3.5.2.5).
P3.5.2.4 AI1 Custom Min % -160 160 0 380 Defines the custom minimum to be
used for bypassing the AI1 Signal
Range (P3.5.2.3).
P3.5.2.5 AI1 Custom Max & -160 160 100 381 Defines the custom maximum to be
used for bypassing the AI1 Signal
Range (P3.5.2.3).
P3.5.2.6 AI1 Signal Inv Normal Inverted Normal 387 Defines the operation of the analog
input 1 signal as follows:
Normal = 0V or 0 mA = 0%, 10V or
20 mA = 100%.
Inverted = 0V or 0 mA = 100%, 10V
or 20 mA = 0%.
P3.5.2.7 AI2 Signal Sel AnIN SlotA.2 388 Defines the location of the signal to
be used as analog input 2.
P3.5.2.8 AI2 Filter Time s 0 300 1 389 Defines the time it takes to reach
63% of a step change in the analog
input signal defined by AI2 Signal
Sel (P3.5.2.7).
