Figure 26. Connection of Analog Inputs 1 and 2 as Digital Inputs 7 and 8.
Index: Example for P0707, applies also to parameter P0708.
P0707[0]: IN000 (AUTO)=1st command data set (CDS).
P0707[1]: IN001 (HAND)=2nd command data set (CDS).
P0725, Operating mode (NPN or PNP) for digital inputs
P0725 determines if a logic 0 or 1 enables digital inputs DIN1 through DIN6 as follows:
0=NPN mode=Active low (logic 0)
1=PNP mode=Active high, (logic 1) factory setting
r0722, Check for signal at digital and analog inputs
Use this parameter to check for the presence of a signal at the digital and analog inputs.
When an active signal is present, the associated segment of the display lights. Figure 27
shows the allocation of each of the inputs to a specific display segment. Figure 28 shows an
example of the display while testing input signals.
