clockwise (and the decreasing count when the shaft is turning
clockwise).
When the option DOWN is set -Direction = DOWN-, if the Counting
direction input has LOW logic level (0VDC) the encoder will provide
the increasing count when the shaft is turning counter-clockwise (and
the decreasing count when the shaft is turning clockwise); on the
contrary if the Counting direction input has HIGH logic level (+VDC)
the encoder will provide the increasing count when the shaft is
turning clockwise (and the decreasing count when the shaft is turning
counter- clockwise).
WARNING
After having set the new counting direction it is necessary to set also
the Index pulse.
4.10 Diagnostic LEDs (Figure 1)
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
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
