5.5 Service displays
Overview of service displays
When "Service Displays" is selected the "Service Overview" window is displayed. Here, the
various operating states are indicated for each machine axis by traffic lights.
A selection of more displays for diagnosing faults also appears:
● Service axis
● System resources
● Configuration Data
● Communications error log
● Action log
Service axis
The information in the "Service axis" display is used to check the following values:
● checking the setpoint branch (e. g., position setpoint, speed setpoint, spindle speed
setpoint prog.)
● checking the actual value branch (e. g. actual position value measuring system 1 and 2,
actual speed value)
● optimizing the position control loop of the axis (e. g. following error, control deviation,
servo gain factor)
● checking the entire control loop of the axis (e. g. through position setpoint/actual-value
comparison and speed setpoint/actual-value comparison)
● checking hardware errors (e.g. by checking the encoder: If the axis is moved
mechanically, the actual position value must change.)
● Checking and setting the axis monitoring functions.

System resource display
The following system resources for the NCU are displayed in the window "NC utilization":
● The net and overall runtime of the position controller, the interpolator and the pre-run in
milli-seconds
● NCU load level as a percentage
● Buffer filling level as a percentage
The display update is stopped using the "Stop" softkey, the displayed values are updated
again with the "Start" softkey.
