If the motor is rotated manualy error "300508 Axis %1 drive %2 zero mark monitoring of motor measuring system" apears. The encoder was configured according to https://support.automation.siemens.com/WW/adsearch/resultset.aspx?region=WW&lang=en&netmode=internet&ui=NDAwMDAxNwAA&term=heidenhain+distance+coded&ID=17823535&ehbid=17823535 What can I do to solve this problem? Thanks in advance for your time,

Does the synchronization is not done properly/ commutation angle offset angles are proper??? /tf/WW/en/Posts/48589 Regards, Prakash

Last year I was making the project and this year i am actually trying to put the torque motor to work but keep on getting the same error 300508 Axis %1 drive %2 zero mark monitoring of motor measuring system. Using a oscilloscope i measure the signals, all seem ok according to heidenhain documentation, except for the zero mark. I know that maybe because it is distance coded it might not be exactly has the documentation says. Can someone check if the signals in the attachment file are ok, or if it needs encoder adjustment or other operation. Thanks in advance for your time, Attachment encoder_signal.zip (230 Downloads)

Also used the oscilloscope to check the angle, and it was very small. The motor runned ok in jog mode, runing a simple program, but after switch the power off the motor does not start again. What can I do sto solve this problem? Thanks in advance for your time,

Are sure that p0404 is the right parameter or are talking about other drive/control, for example 840D sl? Thank's for you time,

You will not find this parameter in 840D this parameter p0404 belongs to solution line...... Regards, Prakash
