Error Diagnosis
E.nEd no ERROR detected
E.ndOH no ERROR drive overheat
E. PU ERROR power unit
NO.PU power unit not ready
E.PUIN ERROR power unit invalid
E.LSF ERROR load shunt fault
E. OL ERROR overload
E.nOL no ERROR overload
E.buS ERROR bus
E.OL2 ERROR overload 2
E.nOL2 no ERROR overload 2
E.EEP E. EEPROM defective
E.PUCO E. power unit common.
E.OH2 ERROR motor protection
E. EF ERROR external fault
E.ENC ERROR encoder
E.nOH no E. over heat pow. mod.
E.SET ERROR set
E.PRF ERROR prot. rot. for.
E.PRR ERROR prot. rot. rev.
E.PUCI E. power unit code inv.
E.PUCH E. power unit changed
E.DRI ERROR driver relay
E.HYB ERROR hybrid
• motor overloaded
• line breakage to the temperature sensor
10 No defined error recognized (should not occur)
11 No longer overtemperature of motor Temperature SENSOR,
SENSOR is again low-resistance.
12 Error: General power circuit fault
13 Power circuit not ready
14 Error: Software version for power circuit and control card are
different. Error cannot be reset.
15 Error: charging relay does not close after the DC bus voltage
reaches its normal operating level. Occurs for a short time during
the switch-on phase, but must automatically be reset immediately
(after 10 sec's E.UP). If the error message remains, the following
causes may be applicable:
• load-shunt defective
• input voltage incorrect or too low
• high losses in the supply cable
• braking resistor incorrectly connected or damaged
• braking module defective
16 Error: Overload error can only be reset at E.nOL, if OL-counter
has again reached 0%. Occurs, if an excessive load is applied
longer than the permissible time (see technical data). Causes:
• poor control adjustment (overshooting)
• mechanical fault or overload in the application
• inverter not correctly sized for application
• motor incorrectly wired
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. The
inverter must remain switched on during the cooling phase.
18 Error: Adjusted time (Watchdog) of communication between
operator and communication bus has been exceeded.
19 Error: Overload while running below 3 Hz. Can only be reset at
E.nOL2, if cool-down time has elapsed.
20 No more overload, the cool-down time is terminated.
21 Error: EEPROM defective. After reset the error is repeated. (para-
meter values changed are erased in the EEPROM)
22 Error: Parameter value could not be written to the power circuit.
Acknowledgment from PC <> OK
30 Error: Electronic motor protective relay has tripped.
31 Error: External error is triggered when a digital input is being
programmed as an external error input.
32 Error: Encoder cable and/or connection wiring
36 Internal or external temperature has dropped to a safe level.
39 Error: Set selection: It has been attempted to select a locked
parameter set.
46 Error: Locked direction of rotation clockwise
47 Error: Locked direction of rotation counterclockwise
49 Error: during the initialization the power circuit could not be recog-
nized or was identified as invalid.
50 Error: Power circuit identification was changed; with a valid power
circuit this error can be reset by writing to SY.3 (application mode).
51 Error: Driver relay. Relay for driver voltage on power circuit has
not picked up although control release was given.
52 Error: Invalid encoder interface identifier
