5.6 Communication with the higher−level controller
(only type SFC−DC−...−IO)
Caution
Long I/O signal cables reduce the immunity to interfer
ence.
·
Do not, therefore, exceed the maximum permitted I/O
signal cable length of 30 m.
Warning
Danger of injury. Faults in parametrizing can cause injury
to people and damage to property.
·
Enable the controller only if the axis system is correctly
installed and parametrized.
·
You must carry out reference travel in the following
cases (position set 0):
with the first commissioning,
when the referencing method is changed,
after each time the logic voltage supply is switched
on!
Use control cable KES−MC−1−SUB−15−... for connecting the
SFC−DC to a higher−level controller (PLC).
Warning
If a voltage is applied and the output pins are used incor
rectly, the device may be seriously damaged, therefore:
·
Do not connect voltage to the outputs.
·
Note the current limit at the outputs.
