OVERCURRENT IN THE POWER SUPPLY |
|
When parameterizing, check the permissible DC bus voltage specified below as a function of the mains input voltage. |
|
Failure to follow these instructions can result in equipment damage. |
Set the parameter MainsVoltageMode (see the following tables).
NOTE: Incorrect parameterization has been detected automatically and diagnostic message 8960 Invalid setting of the mains voltage has been triggered.

The following scenario can lead to a detected device fault:
oParameter MainsVoltageMode = 230 for 230 V (±10 %) 1 AC
oReal mains voltage = 400 V (±10 %) 3 AC
oDuring the precharging phase of the DC bus, a DC bus voltage of 460...560 V occurs due to contact interruptions of one or more phases. This value triggers no diagnostic message for the parameter setting MainsVoltageMode = 230.
oAfter the DC bus charging however, a 400 V mains voltage will be present again if the DC bus relay is closed, for example, due to restoring the contact. This can cause the device to fail after several cycles.
oIf so, the parameter value MainsVoltageMode = 230 V and the real mains voltage of 400 V are saved in the device operating data.
NOTE: Modifications to the parameter are only applied during the Sercos phase up (communication phase 0 => communication phase 4).
