Activation
The following conditions must be fulfilled so that the temperature compensation can be
activated:
1. The compensation type is selected (MD32750, see "Commissioning (Page 227)").
2. The pa
rameters for the compensation type are defined (see "Commissioning
(Page 227)").
3. The axi
s is referenced:
DB31, ... DBX60.4 or 60.5 =1 (referenced/synchronized 1 or 2 respectivelly)
As soon as these conditions are fulfilled, the temperature compensation value for the
position actual value is added to the setpoint in all modes and the machine axis traverses
through this distance. If the compensation value ∆K
x
is positive, the axis moves in the
negative direction.
If the reference position is then lost, e.g. because the encoder frequency has been exceeded
(DB31, ... DBX60.4 or 60.5 = 0), compensation processing is deactivated.
Clock cycle
The compensation values are determined in the interpolation cycle.
Display
The total compensation value calculated from the temperature and sag compensation
functions belonging to the actual position is output in the "Diagnosis" operating area of the
"Axis/Spindle Service" window.
