Display
Plaintext Combivis Value Meaning
E.nEd
no ERROR detected 10 no defined error recognized (should not occur)
E.ndOH
no ERROR drive overheat
11
no longer overtemperature of motor PTC, PTC is again low
resistance.
E.PU
ERROR power unit 12 Error: General power circuit fault.
NO.PU
power unit not ready 13 Power circuit not ready.
E.PUIN
ERROR power unit invalid
14
Error: Software version for power circuit and control card are dif-
ferent. Error cannot be reset.
E.LSF
ERROR load shunt faultl
15
Error: Load shunt relay has not picked up, occurs for a short
time during the switch-on phase, but must be automatically 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 supply cable
- braking resistor wrongly connected or damaged
-braking module defective
E.OL
ERROR overload
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 for the per-
missable time.
Causes:
-poor control adjustment (overshooting)
- mechanical fault or overload in the application
- inverter not correctly dimensioned
- motor wrongly wired
- encoder damaged
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. The
inverter must remain switched on during the cooling phase.
E.buS
ERROR bus
18 Error: Adjusted monitoring time (Watchdog) of communication
between operator and PC has been exceeded.
E.nOL2
no ERROR overload 2
20 No more overload, the cool-down time is terminated.
E.EEP
ERROR EEPROM defec-
tive
21
Error: EEPROM defective. After reset the operation is again pos-
sible (without storage in the EEPROM)
E.PUCO
ERROR power unit com-
mon
22 Error: Parameter value could not be written to the power circuit.
Acknowlwdgement from PC <> OK
E.OL2
ERROR overload 2
19 Error: Overload can only be reset at E.nOL2, if cool-down time
has elapsed.
E.EF
ERROR external fault
31
Error: External error. Is triggered, if a digital input is being pro-
grammed as external error input and trips.
E.OH2
ERROR motor protection
30 Error: Electronic motor protective relay has tripped
E.Sbus
ERROR bus synchron
23 Error: Sercos - Synchronization not possible
E.PFC
ERROR power factor con-
trol
33 Error: In the power factor control.
E.ENC
ERROR encoder
32 Error: Cable breakage resolver or incremental encoder.
E.nOH
no E. over heat power
module
36 No more overtemperature of power module.
