4.10 Diagnostic LEDs (Figure 1) (IP-, CKP- models only)
NOTE
The Diagnostic LEDs are only available on IP-, CKP- models.
Two LEDs located in the rear side of the encoder enclosure are intended to show
visually the work status of the device as explained in the following table.
GREEN LED
(status)
Description
ON The encoder is supplied and running properly
OFF
The encoder is off; an error occurred in the ASIC
while reading the disk
RED LED
(microcontroller error)
Description
ON
It warns of the presence of an error:
1 SPI communication error between the
microcontroller and the ASIC designed to read
the disk
2 An error occurred at power on while
uploading the configuration data from the
EEPROM
3 An error occurred while reading the encoder
position immediately after starting the
encoder or after setting either the resolution
or the counting direction
4 Communication error between the encoder
and the PC
4.11 Index pulse setting external button (Figure 1) (IP-, CKP- models
only)
NOTE
The Index pulse setting external button is available only on IP-, CKP- models.
This encoder provides the zero signal (Index pulse) once per revolution as
relative positioning reference (home position, see the Figure on page 20). In this
way a unique position can be identified at a well-known point in the 360°
revolution of the encoder shaft. The external button located in the rear side of
