• 
  E.EEP Error! EEPROM defective t 21 After reset the operation is again possible (without storage in the
  EEPROM)
  
• E. EF Error! external fault 31 Error: External error. Is triggered, if a digital input is being programmed
  as external error input and trips.
• 
  E.EnC Error! Encoder cable 32 Cable breakage at the resolver or incremental encoder
• 
  E.Hyb Error! hybrid 52 Invalid encoder interface identifier.
• 
  E.HybC Error! hybrid changed 59 Error: Encoder interface identifier has changed, it must be confirmed
  over ec.0 or ec.10.
• 
  E.iEd Error! input error detect 53 Hardware failure at the NPN/PNP change-over or at the start/stop
  measurement.
• 
  E.InI Error! initialisation MFC 57 MFC not booted.
• 
  E.LSF Error! load shunt fault 15
  Load-shunt relay has not picked up. occurs for a short time during the
  switch-on phase, but must automatically 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
  braking resistor wrongly connected or damaged
  braking module defective
• 
  E.ndOH no ERROR drive overheat 11 Motor temperature switch or PTC at the terminals T1/T2 is again in the
  normal operating range. The error can be reset now.
• 
  E.nOH no E. over heat pow.mod. 36 Temperature of the heat sink is again in the permissible operating range.
  The error can be reset now.
• 
  E.nOHI no ERROR overheat int. 7 No longer overheating in the interior E.OHI, interior temperature has
  fallen by at least 3°C
  
• E.nOL no ERROR overload 17
  No more overload, OL-counter has reached 0%; after the error E.OL a
  cooling phase must elapse. This message appears upon completion of
  the cooling phase. The error can be reset now. The inverter must remain
  switched on during the cooling phase.
• 
  E.nOL2 no ERROR overload 2 20 The cooling time has elapsed. The error can be reset

• 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.
