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
Brake resistor not connected.
Brake resistor too high resistance.
Brake resistor functionality not activated.
Several servo drives are decelerating with in-
sufficient ramp time.
Mains voltage out of range

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.

Possible solution
Check the brake resistor cabling.
Check if the lowest resistance value has been entered.
Activate the brake function.
• Avoid simultaneous deceleration of several servo
drives.
• Change the deceleration speed.
Check the mains voltage and wiring.
