8.4.1 Service axis

Function

The information in the "Service Axis" display is used to

• check the setpoint branch (e.g., position setpoint, speed setpoint, spindle speed setpoint prog.)
• check the actual-value branch (e.g. position actual value, measuring system 1/2, actual speed value), optimize the position control of the axis (e.g. following error, control difference, servo gain factor)
• check the entire control loop of the axis (e.g. through position setpoint/actual-value comparison and speed setpoint/actual-value comparison)
• check hardware faults (e.g. encoder check: If the axis is moved mechanically, the actual position value must change)
• set and check axis monitoring functions.

Additional information

The program PlcSymbolsGenerator.exe and its description are located in the PLC tool box. It creates the files with symbols and language-dependent texts in the representation required for the HMI.

Prerequisites

Preparation of PLC data:

• Save the files created with PlcSymbolsGenerator.exe in the Services operating area under path: Diagnostics/PLC Data (F:\DH\DG.DIR\PLC.DIR\ ) with the following predefined names and extensions:
  • PlcSym.SNH (symbols)
  • PlcSym_.SNT (texts e.g. PlcSym_GR.SNT)
• NC RESET or reboot HMI to activate file
• Only for M:N configurations: There must be an entry which makes the symbols available in netnames.ini for each addressable NCU.
