12816 0x3210 DC bus overvoltage Keypad display: DC Bus OV
Cause Error type/response Remedy
DC-bus voltage has exceeded the error thresh-
old 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 seng of the rated mains volt-
age in 0x2540:001 (P208.01).
Fault
•
Reduce dynamic performance of the load
prole.
•
Check mains voltage.
•
Check sengs for brake energy manage-
ment.
•
Connect brake resistor to the power unit and
acvate the integrated brake chopper.

12817 0x3211 DC bus overvoltage warning Keypad display: Warn.DC Bus OV
Cause Error type/response Remedy
DC-bus voltage has exceeded the warning
threshold for overvoltage set in 0x2540:005
(P208.05) due to a too high braking energy or a
too high mains voltage.
Warning
•
Reduce dynamic performance of the load
prole.
•
Check mains voltage.
•
Check sengs for brake energy manage-
ment.
•
Connect brake resistor to the power unit and

12832 0x3220 DC bus undervoltage Keypad display: DC Bus UV
Cause Error type/response Remedy
DC-bus voltage has fallen below the error
threshold for undervoltage. The error threshold
(display in 0x2540:003 (P208.03)) results from
the seng of the rated mains voltage in
0x2540:001 (P208.01).
Trouble
•
Check mains voltage.
•
Check DC-bus voltage.
•
Check mains sengs.
