Re: How close can the wires be ? - Advice needed.

Couple of things.

The encoder circuit goes into a squaring circuit (Schmidt trigger)
followed by a 5uS low-pass filter, followed by another squaring
circuit. This makes the encoder inputs totally insensitive to noise
pulses narrower than 5uS.

This has been tested with a 20' (3 meter) long cable having the motor
leads and unsheilded encoder leads bundled together, just like you
are not supposed to do. A scope couldn't even pick out the encoder
signals yet the servo worked just fine.

Second, the ERR/RES input was passivated so it would not respond
to "fault" inputs lasting less than 3 mS. The entire fault circuit
was redesigned to do what it was supposed to do quickly internally
(respond within 2uS to a short-circuit), yet not false-trigger on an
external "fault" input such when another drive was forcing it into
fault (the 3 mS part).

The REV7 is easy to use and has no bad habits at all.
