4 TROUBLESHOOTING
This chapter covers troubleshooting of the P5000 drive.
4.1
Maintaining the P5000
The P5000 drives are designed for minimum maintenance. The following cleaning procedure,
performed as needed, will minimize problems due to dust and dirt build-up. Remove
superficial dust and dirt from the unit using clean, dry, low-pressure air.
The P5000 drive has an internal protection fuse. If the STATUS LED isn't lit, it indicates no
power is connected to the drive or the drive's internal protection fuse is blown. If it is
suspected that the internal protection fuse is below, please return the P5000 drive to
Kollmorgen for repair or replacement.
4.2
Troubleshooting the P5000
The P5000 has a STATUS LED to indicate drive status. This STATUS LED displays the
condition of the power stage. When the drive is operating normally, the STATUS LED is solid
or flashing green. When the protection fault latch has been set, the STATUS LED is red. A
miss-wired motor or a motor short-circuit results in the protection latch being set.
Cycling the DISABLE IN input clears the internal fault protection latch; if the problem causing
the fault has not been resolved, the latch will be immediately set again and the STATUS LED
will continue to be red.
Normally, the STATUS LED will be red for 1 second after power-up and then become green. If
the STATUS LED is not lit, it indicates no power is connected to the drive or the drive's internal
protection fuse is blown.
