Val-
ue
Meaning
E.buS Error ! Watchdog 18
Adjusted monitoring time (Watchdog) of communication be-
tween operator and PC / operator and inverter has been ex-
ceeded.
E.EEP Error ! EEPROM defective 21
After reset the operation is again possible (without storage in
the EEPROM)
E. EF Error ! External fault 31
Is triggered, if a digital input is being programmed as external
error input and trips.
E.LSF Error ! Load shunt fault 15
The load-shunt relay has not picked up. This occurs for a
short time during the switch-on phase, but must automati-
cally be reset immediately. If the error message remains the
followingcausesmaybeapplicable:
load-shunt defective
input voltage wrong or too low
high losses in the supply cable
E.Frlr
Error fault reset level
reached
41
Error "Fault reset level reached" is triggered when the adjust-
ed value in parameter Pn.15 is reached within one hour. The
error can be reset.
E.nEt ERROR! Mains 3 One or more phases are missing.
E.FnEt Error ! Mains frequency 40 Mains frequency outside the adjusted tolerance range (cS.03)
E.nOH
No error over heat power
module
36
No longer overheating in the interior E.OHI, interior tempera-
ture has fallen by at least 5°C, error can be reset
E.nOHI No error internal overheat 7
E.nOL No error overload 17
no overload, OL counter reaches 0 %; a cooling down phase
must be awaited after error E.OL. This message appears
upon completion of the cooling phase. The error can be re-
set. The inverter must remain switched on during the cooling
phase.
E. OC Error ! Overcurrent 4
Occurs,ifthespeciedpeakcurrentisexceeded.Causes:
acceleration ramps too short
short-circuit at the output
ground fault
overload too high (e.g., deceleration ramp too high at the in-
verter)
wrong parameterization
E.OH
Error ! Power module tem-
perature
8
Overtemperature of power module. Error can only be reset
at E.nOH, if the temperature has dropped by at least 5 °C.
Causes:
insufcientairowattheheatsink(soiled)
ambient temperature too high
ventilator clogged
E.OHI Error ! Interior temperature 6
Overheating in the interior.error can only be reset at E.nOHI,
if the interior temperature has dropped by at least 5 °C.
E. OL Error ! Overload (Ixt) 16
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:
Overload in the application
