3.
Enter the actual value corresponding to the approached position in MD34100
REFP_SET_POS. This value may be a specified design value (e.g. fixed stop) or can
now be determined with a measuring instrument.
4.
Set MD34210 ENC_REFP_STATE to "1" to enable the "calibration" function.
5.
The modified machine data become effective after a RESET.
6.
Switch to JOG-REF mode.
7.
If you press the traversing key already used in step 2, the current offset is entered in
MD34090 REFP_MOVE_DIST_CORR and MD34210 ENC_REFP_STATE changes to
"2", i.e. the axis is considered to be calibrated. (The screen is updated by pressing the
traversing key.)
Note
The axis does not move when the correct traversing key is actuated! The value entered in
MD34100 REFP_SET_POS appears in the actual value display of the axis position.
8.
Exit JOG-REF operating mode. The calibration operation for this axis is now complete.

Secondary conditions for absolute encoders
18.5.1
Calibrating absolute encoders
Calibration time
The calibration process determines the offset between the machine zero and the encoder
zero and stores it in a non-volatile memory. Normally, calibration need only be performed
once, i.e. during first commissioning. The control then knows the value and can calculate the
absolute machine position from the encoder absolute value at any time. This status is
identified by MD34210 ENC_REFP_STATE=2.
The offset is stored in MD34090 REFP_MOVE_DIST_CORR.
The calibration process must be repeated in the following situations:
●
After mounting/removal or replacement of encoder or of motor with built-in encoder.
●
After change of an existing gear unit between motor (with absolute encoder) and load.
●
Generally speaking, every time the mechanical connection between the encoder and load
is separated and not reconnected in exactly the same way.
