Diagnostics of operational state errors
The following information is also provided to assist in the analysis of operational state errors
such as:
•
Despite an active motion command, the axis does not move.
⇒ Check whether controller is enabled. In controller mode, position control or speed
control (with spindle control) must be activated.
•
Occurrence of feed fluctuations.
⇒ Detection via following error or actual speed value.
•
Incorrect positioning.
⇒ Compare position setpoint with actual position value of measuring system 1/2 and
absolute compensation value of measuring system 1 or 2.
•
The cam is not detected by the PLC during referencing.
⇒ Check status display "referenced"
•
An incorrect reference point value was displayed.
⇒ The wrong measuring system may have been used for referencing.
•
Large fluctuations in the actual speed value are occurring in the main spindle drive.
⇒ The selected actual speed range for encoders is too high or the machine datum:
MD36300 $MA_ENC_FREQ_LIMIT [n] (encoder limiting frequency)
is set higher than specified in the encoder data sheet.
Incorrect spindle positioning occurs.
⇒ The wrong measuring system may be selected or synchronization may have been
performed with the wrong zero mark.
