Hello to all
I have a problem with encoder from bei sensors.
encoder is dual with ttl and ssi channels.
When i turn off and turn on my system it gives me different position than it was before power off.
We have custom control unit that evaluate ssi and ttl signals. We tried different ssi modul from Lenze and same thing happens.
Encoder is on motor with electomagnetic brakes. Manufacturer told us that magnetics is the problem and sent differet type of encoder but same thing happens.
Cable is twisted pairs and shileded. Length is 15m max.
Everything works normal bud after power off and on we haave different position value and if drive went positive before power off new value is smaller than what was before power off
Exmple:
Drive moves from 10.456 to 12.665, off/on, new position is 10.354
Drive moves from 13.445 to 11.344, off/on, new position is 13.221
Any suggestions?
Thanks in advance
