hi all
After Replace the X Servo DRive i could Home the Machine for the first time...
Now i habe to trouble shooting the Spindle / Spindeldrive / PLG / Encoder.
I did clean the Spindle motor and the fan. i cleand also the Pulscoder Sensor. Probably now is to near at the tooth. I have more than 2 V on the PA / PB Channel...I cannot reduce with the gain pot lower. ==> I need to reopen the Motor and remove the fan and increase some space between the tooth and the sensor. will do that tomorrow. Signalform 2 Sinus with 90° offset is ok.
Then,
I checked the Encoder on the Spindle by osciloscope. CH 52/53 A / B rectangle Signal are fine. BUT it seems the Index pulse is from always 5V to 0v instead opposite (CH54) Very strange. Has someone a tip? At least the Index is here... Or is the Index cable wrong connected with the reversed Index signal to ch54??
Then, if i turn off Switch 6.2 OpenLoop Speed Loop, i still cannot increase Spindle Speed, yet the spindle turns at creep speed...and i can switch on and off.
Also with Switch 6.1 off Oriental test does not work...Probalbly because the Encoder Index signal is inverse..(above on osciloscope)Button 2 starts the spindel but never does stop, probably because index is not found..
Then another question: How does Mazatrol M2 Speed rpm send to the Freqrol...by digital BCD or Binary or 10V analog?
Last question again, Spindle should work without PLG (open loop mode) right?? Even the orient Encoder is not necessary?
I am very grateful for any hint!
Best regards
Martin
