Digital inputs/outputs DIO1 and DIO2
(XDIO:1 and XDIO:2)
Input/output mode selection by
parameters.
DIO1 can be configured as a frequency
input (0…16 kHz with hardware filtering of
4 microseconds) for 24 V level square
wave signal (sinusoidal or other wave form
cannot be used). DIO2 can be configured
as a 24 V level square wave frequency
output. See the firmware manual,
parameter group 11.
