78 The control unit
Connector data
Power supply (XPOW)
Relay outputs RO1...RO3
(XRO1...XRO3)
+24 V output (XD24:2 and XD24:4)
Digital inputs DI1...DI6
(XDI:1...XDI:6)
Start interlock input DIIL (XDI:7)
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.
