Error and Status Display
Display COMBIVIS display dec hex Meaning
E. OC Error ! overcurrent 4 4 Occurs, if the specied peak current is exceeded.
Short cicuit at the output
Ground fault
motor cable too long
Phase error
EMC
The load is too big at turned off constant current
limit.
DC brake at high ratings active
Deceleration ramp or stopping jerk is adjusted too
short.
Braking transistor defective or missing
Acceleration ramp or stopping jerk is adjusted too
short.
The load is too big at turned off acceleration stop.
E. OH Error ! heat sink tem-
perature
8 8 Error: Overtemperature of power module. Error can
only be reset at E.nOH.
Installation position and minimum distances wrong
ambient temperature too high
Fan clogged or defective
insufcient air ow at the heat sink (soiled)
E.OH2 Error ! motor protec-
tion
30 1E Electronic motor protective relay has tripped (see
motor protection function of the inverter).
E.OHI Error ! overheat
internal
6 6 Error: Overheating in the interior: If the interior tem-
perature has dropped by at least 3 °C, E.nOHI is
displayed. Then the error can be reset.
E. OL Error ! overload (Ixt) 16 10 An overload exceeded the permissible time (depen-
dent on short time current limit and overload characte-
ristic). Overload error can only be reset if OL-counter
reaches 0% again and E.nOL is displayed.
motor wrongly wired motor wrongly wired
inverter not correctly dimensioned
encoder damaged
poor control adjustment (overshooting)
Mechanical error (moved too hard, blockade) or
