Start interlock input DIIL
(XDI:7)
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.
Reference voltage for
analog inputs +VREF and -
VREF
(XAI:1 and XAI:2)
Analog inputs AI1 and AI2
(XAI:4 ... XAI:7).
