Troubleshooting
• If the error persists on only one drive, physically swap the
drives using the following procedure:
a
Shut down the PC, turn off the
START
key and disconnect
the mains.
b
Remove the rear access panel and locate the drives on the
control panel.
c
Disconnect all the cables from the drives, making notes on
where are they connected to.
d
Physically swap the drives, and connect the cables again.
e
Power up the machine, reset the E-Stop circuit, and start
the sj5000 software.
f
If the error is reported on the same drive, then the drive is
faulty and should be replaced.
g
If the error is now on the other drive, then there is a
problem with the cable or with the encoder head.
Note that there are two cables from the drive to the encoder
head. Either could be faulty, so further investigation is
needed to locate the problem. This requires a spare encoder
head and cables.
