P0707 to P0708
Analog inputs 1 and 2 can be reconfigured with parameters P0707 and P0708 as
digital inputs if required.
The following limit values apply to analog inputs configured as digital inputs:
≤
1.6 VDC = Off.
≥
4.0 VDC = On.

P0725
Operating mode for the digital inputs NPN or PNP
This parameter determines whether the digital inputs DIN1 to 6 are to be enabled by
“logic 0” or “logic 1”.
Possible settings:
0
NPN mode
Þ
active low.
1
PNP mode
Þ
active high (factory setting).

Check of the digital and analog inputs
This parameter can be used to check the functions of the digital and analog inputs. You
can check the presence of a signal at the channel.
When an active signal is present, the associated segment of the display lights up. The
allocation of each of the inputs to a specific segment is illustrated below.
