Evaluation of the
control signals and
generation of the
status values every
300
m
s
1) When using incremental encoders without a zero
mark, the two signals N and N must be connected
to different potential (5.2 V DC / M) externally.
2) For 0I0 and 1I0, a shielded cable must be used.
3) Age of sensor values depends on transmission
technique and processing.
4) Sensors with a monoflop time longer than 64
m
s
cannot be used with the IM178-4. The time 2 x
(1/baud rate) must be added to the specified
values.
