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)
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
Firmware Manual, parameter
group 12.
Reference voltage for analog
inputs +VREF and -VREF
(XAI:1 and XAI:2)
Analog inputs AI1 and AI2
(XAI:4 ... XAI:7).
Current/voltage input mode
selection by jumpers. See
page 88.
