0x3210

Remedy

Reduce dynamic performance of the load profile.

Check mains voltage.

Check settings for brake energy
management.

0x2541:001 (P706.01) = [0]: Connect brake resistor to the power unit and activate the integrated brake chopper

Cause

DC-bus voltage has exceeded the error threshold for overvoltage due to a too high braking energy or a too high mains voltage. The error threshold (display in 0x2540:006 (P208.06) results from the setting of the rated mains voltage in 0x2540:001 (P208.01).

Remedy

Check drive sizing. 

  • Reduce the maximum current of the inverter 0x6073 (P324.00). 
  • In case of high mass inertias, reduce maximum current of the inverter 0x6073 (P324.00) to 150 %.
Cause

Device utilisation (ixt) too high by frequent and too long acceleration processes.

Remedy

Check drive sizing.

  • Check machine/driven mechanics for excessive load.
  • Check settings of the motor data.
  • Reduce values for slip compensation 0x2B09:001 (P315.01), 0x2B09:002 (P315.02) and oscillation damping 0x2B0A:001 (P318.01), 0x2B0A:002 (P318.02).
Cause

Motor thermally overloaded, e. g. by an impermissible continuous current or by frequent or too long acceleration processes.
