Please note
Observe the following when connecting a rotary pulse
generator:
·
Do not connect the potentials of the ENCODER connec
tion with other potentials.
·
Use only suitable rotary pulse generators, e.g. encoders
from the Festo range.
Operating system version ...E must be used for evaluating the
encoder signals.
