Details
24VDC power supply for the DI
When source logic is selected, it becomes the common
point of input
(do not short to terminal L)
This terminal is used as the common terminal of the DI.
For internal supply (and voltage-free contacts):
Short between P24 and PLC: Sink logic (the current will flow from the MX2 input to the
output)
Short between CM1 and PLC: Source logic (the current will flow from the output to the
MX2 input)
Sum of input [1]~[7] currents (return)
It is possible to allocate any of the digital multifunction
inputs to this terminals.
When safety function is enable by hardware dip-switch
multifunction setting 77:GS1 amd 78:GS2 are compul-
sory for terminals 3 and 4 and functionality change
based on ISO13849-1
For PTC connect the motor thermistor between termi-
nals 5 and L and assign 19:PTC on parameter C005.
Inverter will trip when thermistor exceed 3kOhm.
For pulse train input B set 85:EB in C007 parameter.
Max freq for this terminal is 2kHz.
32 kHz max.
Common is [L]
Any multifunction output signal can be set to this ter-
minals.
In case the EDM is selected, the functionality is based
on ISO13849-1

10 VDC 32 kHz maximum
Any multifunction output signal can be set to this ter-
minals.
