Fault Subcodes

Fault Subcodes can be viewed in parameters 543, 545, 547, 549, 551, 553, 555,
and 557 [Fault

x Subcode]. Each of these parameters corresponds with

parameters 243, 245, 247, 249, 251, 253, 255, and 257 [Fault

x Code],

respectively. For example, if parameter 243 [Fault 1 Code] displays “5” and
parameter 543 [Fault 1 Subcode] displays “273”, an over voltage fault (F5) has
occurred in the power unit of the drive.
