Digital inputs/outputs
DIO1 and DIO2
(XDIO:1…XDIO:4)
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.
