9.2.2.3 DC-link Voltage Too High (Error 0x3210/0x103)
This fault applies to PSM 510.
Possible Causes
•
Brake resistor not connected.
•
Brake resistor too high resistance.
•
Brake resistor functionality not activated.
•
Several servo drives are decelerating with insufficient ramp time.
•
Brake resistor configured incorrectly.
•
Mains voltage out of range.
Troubleshooting
Table 35: Fault, DC-link voltage Too High
Possible cause
Possible solution
Applies to:
Brake resistor not connected.
Check the brake resistor cabling.
PSM 510
Brake resistor too high resistance.
Check if the lowest resistance value has been entered.
PSM 510
Brake resistor functionality not activated.
Activate the brake function.
PSM 510
Several servo drives are decelerating with in-
sufficient ramp time.
•
Avoid simultaneous deceleration of several servo
drives.
•
Change the deceleration speed.
DAM 510, PSM 510,
ISD 510/DSD 510 servo
drives, SDM 511/
SDM 512 servo drive
modules
Mains voltage out of range
Check the mains voltage and wiring.
9.2.2.4 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.
9.2.2.5 DC-link Overcurrent (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.
