Dear Colleagues,
We have one 3rd-party motor with SSI encoder. we have tested it with our HCS01, it'OK. when move to ctrlX Drive with XG21 EC interface,it always reports "C1108 error during encoder intitalization". please see the picture below, but I don't know how to upload the par. file.
Could you help to provide any suggestions? thank you!
Best Regards,
Henry
Hello Henry_Hua,
if looking to your drive parameter file still the firmware version 0308 is present. Please update the firmware correctly.
The diagsnostic trace is telling problems with the timing, see:
You might change the settings from
to
Check these settings wiht what the encoder manufacturer is telling or send to us the specification of the SSI encoder.
Otherwise anyway the following menues should be corrected:
Old settings:
should be changed to:
The the behavior is like this:
Hello Henry,
Check all the frequency ranges of the protocol.
In my case with a Balluff SSI Encoder only the 1000 KHz worked.
You still have the 100 kHz in the example.
Dear Mr. Luis,
Yes, we use the same cable and also check the connectors serval times. As you know, the EC interface of ctrlX for SSI is the same as the HCS01. once we chage the motor and encoder cable to HCS01, it runs well and without anyproblem.
Please see the data sheet below. this encoder is made by the customer itself who also produce the motor. thank you!
Best Regards,
Henry
Hi, we have exp. with SSI encoder and ctrlX drive and we did not face parametrization issue.
Have you tried to use Telegram 1? As long as you do not use any status and other bits, it´s not relevant setting.
Only issue we have faced is very strange noise and vibration every 2,3 s -> to eliminate it we had to set P-0004 to 2500 us (do not ask me why:)).
Regards, P.
