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
