Possible causes
Phase-to-phase short.
Short on backlink.
Short on hybrid cable.
Short on EXM 510 connector or cable.
Short on ISD 511 connector.
Troubleshooting
Check the cabling
Check for loose connections.
9.3.3 DC-link Voltage Too Low (Error 0x3220/0x104)
This fault applies to all system modules.
Possible cause
Incorrect mains input supply.
Troubleshooting
Check that the supply voltage matches the allowed specification.
9.3.4 Current Overload Trip (Error 0x2396/0x15C)
This fault applies to the PSM 510 and the DAM 510.
Possible causes
The sum of the servo drive current exceeds the maximum rating of the DAM 510.
The sum of the system modules' current exceeds the maximum rating of the PSM 510.
Short on backlink.
Troubleshooting
Check the servo drive current consumption.
Avoid simultaneous acceleration of all servo drives.
Decrease the acceleration value.
9.3.5 High Cont. Power Overload (Error 0x2313/0x161)
This fault applies to the PSM 510.
Possible causes
The PSM 510 was operating at over 140% of the nominal power rating for too long.
Troubleshooting
Check the current consumption.
9.3.6 Continuous Power Overload (Error 0x2314/0x162)
This fault applies to the PSM 510.
Possible causes
The PSM 510 was operating at 100–140% of the nominal power rating for too long.
Troubleshooting
Check the current consumption.
9.3.7 AUX Overcurrent (Error 0x2391/0x125)
This fault applies to the DAM 510.
Possible causes
The servo drives are consuming more power on the U
AUX
line than allowed.
Troubleshooting
Ensure that the number of servo drives on 1 line does not exceed 68.
