Analog signals are converted to digital signals inside the drive using Analog to Digital Converters.
The user must select either Voltage (default) or Current using the 2 switches on the I/O board
DIP1(1,2). Additionally, P0756 must also be set accordingly.
Example using voltage input
DIP SW 1
(Analog Input 1)
ON (UP) = 0 to 20mA
OFF = 0 to 10V
Possible settings of P0756:
0 Unipolar voltage input ( 0 to 10 V )
1 Unipolar voltage input with monitoring (0 to 10 V )
2 Unipolar current input (0 to 20 mA)
3 Unipolar current input with monitoring (0 to 20 mA)
4 Bipolar voltage input (-10 V to +10 V) (only AIN1)
