3.10 Commissioning function (Teach-in function for linear axes)
This function is activatable in the parameterization.
When the commissioning function is activated, the relevant distance can be traversed
with the machine. On the basis of the input "requested number of units per distance
traveled", the encoder automatically calculates its measuring length in increments
from the position difference and the selected measuring units. This value can then be
entered in the parameterization file, so that the teach-in process does not need to be
repeated should the encoder be exchanged.
For the Teach-In procedure following reductions are valid:
•
The number of the revolutions must be programmed fixed to 4096 and may not be
changed in the parameterization!
•
The maximum displacement distance mustn't exceed 2048 revolutions
•
During the Teach-In process the maximum number of increments per revolution of
the encoder mustn't be exceeded (e.g. specification of a measuring length of 3000
increments and indication of a displacement distance of ¼ of a revolution)
•
For rotating applications the commissioning function is not suitable and not valid
When the teach-in function is activated, the green LED flashes at a frequency of
approx. 1 Hz.
To remain downward compatible to the version of 3.x, in the parameter setting there
are three different settings:
•
OFF, no status:
This setting is compatible with version 3.x, that means the bits 2
25
to 2
31
are
always "0".
•
OFF, with status:
In this setting the status bits are visible, but the function is not activated
•
ON, with status
The commissioning function is active
