J4-1
The general purpose inputs are a bank of four inputs that share
a common terminal, DINP COM, on J4-1. The inputs operate
over a wide input voltage range of ± 4.0 to ± 30 volts.
General purpose inputs are compatible with either sourcing or
sinking currents to provide maximum flexibility for interfacing to
field wiring.
Common Rail for Inputs 1 through 4. Common can be tied to
positive supply or negative supply, depending on the
application need.

Input current is a function of the input voltage and listed in the following table.

The response time for DINP1, DINP2 and DINP3 is less than 1 ms. MSINP1 has a
response time of less than 100 µs.
NOTE
For fastest response to an input, configure the drive to respond
when the input opto isolator is turned on (current starts flowing in
the photo diode).
