Value Meaning
E. OC
Error ! overcurrent
4
Occurs, if the specified peak current is exceeded. Causes:
acceleration ramps too short
the load is too big at turned off acceleration stop and turned off constant
current limit
short-circuit at the output
short-circuit at the output
deceleration ramp too short
motor cable too long
EMC
DC brake at high ratings active (see 6.9.3)
E. OH
Error ! overheat pow.mod.
8
Error: Overtemperature of power module. Error can only be reset at
E.nOH. Causes:
insufficient air flow at the heat sink (soiled)
ambient temperature too high
ventilator clogged
E.OH2
Error ! motor protection
30
Electronic motor protective relay has tripped.
E.OHI
Error ! overheat internal
6
Error: Overheating in the interior: error can only be reset at E.nOHI, if
the interior temperature has dropped by at least 3 °C.
E. OL
Error ! overload (Ixt)
16
Error: Overload error can only be reset at E.nOL, if OL-counter reaches
0% again. Occurs, if an excessive load is applied longer than for the
permissible time (see technical data). Causes:
poor control adjustment (overshooting)
mechanical fault or overload in the application
inverter not correctly dimensioned
motor wrongly wired motor wrongly wired
encoder damaged
E.OL2
Error ! overload 2
19
Occurs if the standstill constant current is exceeded (see technical data
and overload characteristics). The error can only be reset if the cooling
time has elapsed and E.nOL2 is displayed.
E. OP
Error ! Overvoltage
1
Voltage in the DC-link circuit too high. Occurs when the DC bus voltage
rises above the permissible value. Causes:
poor controller adjustment (overshooting)
input voltage too high
interference voltages at the input
deceleration ramp too short
braking resistor defective or too small
E.OS
Error ! over speed
58
Real speed is bigger than the max. output speed.
E.PFC
Error ! Power factor control
33
Error in the power factor control
E.PrF
Error ! prot. rot. for.
46
The drive has driven onto the right limit switch. Programmed response
„Error, restart after reset” (see chapter 6.7 „Response to errors or
warning messages”).
E.Prr
Error ! prot. rot. rev.
47
The drive has driven onto the left limit switch. Programmed response
„Error, restart after reset” (see chapter 6.7 „Response to errors or
warning messages”).
E. Pu
Error ! power unit
12
Error: General power circuit fault
E.Puci
Error ! Unknown power unit
49
Error: During the initialization the power circuit could not be recognized
or was identified as invalid.
