3.3 Turning a drive on
When powering up the DDS module or doing a reset, various messages
appear on the seven - segment display:
1. Initialization stages: they show values of 1, 2, 3 and 4.
2. Software version, after the r with the identifying digits.
3. Error listing.
4. Warning listing.
5. Return to step 3.
Stages shown on the 7-segment display:
Its purpose is to verify that the startup stages are being executed properly. The
information sequences that it is showing in the start-up process have the
following meaning:
1. Initialization stage: After the display is turned off, digits 1, 2, 3 and 4
·see a· are shown which correspond to the 4 initialization stages. The
display then turns back off.
2. Software version displaying stage: It shows the software version loaded
in the module. It first shows the letter r (indicating the version “release”),
followed by the version number (digit by digit) ·see b·. When the drive is
active and the axis is being governed, the display will show the zero
digit with a blinking dot · see c ·.
While loading parameters, the display only shows the middle segment
·see e ·
When the drive (in a system with SERCOS-II interface) is not in stage 4, i.e.
the system communication between the CNC and the modules has not
finished initializing and although the light ring is closed, it has not gone up to
the next stage, the display shows a smaller fixed zero · see d · (not blinking).
If this zero (smaller) is not fixed (blinks) it means that the light ring is not
closed (the light does not reach) or there is too much distortion.
This indication permits detecting which section of the optical fiber is
causing the problem (or which drive is not sending light).
Hence, the module whose display blinks this smaller zero is the one that is
not receiving light at the input.
