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 ½, 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, then the position actual value must change)
· set and check axis monitoring functions.
