Cable length
2)
: Max. 150 m
Input frequency: Max. 500 kHz
Subdivision factor: 4096-fold
Signal adjustment: Automatic
adjustment of offset, phase and
amplitude
1)
Only for "Recording" operating mode and depends on
firmware version (see the User’s Manual for Application
Development)
2)
The specified cable length applies when HEIDENHAIN
cables are used; the supply voltage range of the
encoder must be maintained!
Measured-value trigger
Storage of measured value alternatively through exter-
nal or internal trigger (see User’s Manual for Application
Development)
External
Signal via trigger input
Software command (via
Ethernet)
Internal Timer
Reference position of axis 1
(absolute or delta value)
Traversing of reference marks
