Drive Service Display (For Digital Drives Only) - Siemens SINUMERIK 828D Function Manual

D1: Diagnostics tools
5.3 Service overview
Diagnostics of operational state errors
Further, information of the service display "Axis/spindle" can be used to investigate incorrect operating states
such as e.g.:
• Although there is a travel command, the axis does not traverse.
⇒ Check whether the controller has been enabled. In controller mode position control or speed control (with
spindle control) must be activated.
• When feedrate fluctuations occur:
⇒ Detected using following error or speed actual value.
• Incorrect positioning
⇒ Compare position setpoint with actual value, measuring system 1/2 and abs. compensation value,
measuring system 1/2.
• The cam is not detected by the PLC during referencing.
⇒ Check status display "referenced"
• An incorrect reference point value is displayed.
⇒ Referencing was possibly performed with the incorrect measuring system.
• For a main spindle drive, significant fluctuations occur in the speed actual value.
⇒ Speed range for the encoder has been selected too high or the machine data
MD36300 $MA_ENC_FREQ_LIMIT [n] (encoder limit frequency) is set higher than is specified in the encoder
data sheet.
• Incorrect spindle positioning occurs.
⇒ An incorrect measuring system is possibly selected or synchronization with the incorrect zero mark.

Drive service display (for digital drives only)

Displays
Displays on the control's user interface that show values and statuses allow for evaluation of the operating
statuses of the digital drives.
Access
For the purposes of commissioning and diagnosing
• feed drives (FDD) and
• main spindle drives (MSD)
