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
• 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 if the DC-link circuit voltage exceeds 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 pow. unit code inv. 49 Error: During the initialization the power circuit could not be
recognized or was identified as invalid.
E.Puch ERROR power unit changed 50 Error: Power circuit identification was changed; with a valid
power circuit this error can be reset by writing to SY.3. If the
value displayed in SY.2 is written, only the power-circuit
dependent parameters are reinitialized. If any other value is
written, then the default set is loaded.
E.PUCO ERROR power unit commun. 22 Error: Parameter value could not be written to the power
circuit. Acknowledgement from PC <> OK
E.PUIN ERROR power unit invalid 14 Error: Software version for power circuit and control card are
different. Error cannot be reset (only at F5-G B-housing)
