Error Messages
E. br
Error ! brake
56
Error: can occur in the case of switched on brake control (see chapter
6.9.5), if
the load is below the minimum load level (Pn.43) at start up or the
absence of an engine phase was detected
the load is too high and the hardware current limit is reached
E.buS
Error ! Watchdog
18
Adjusted monitoring time (Watchdog) of communication between
operator and PC / operator and inverter has been exceeded.
E.Cdd
Error ! calc. drive data
60
Error: During the automatic motor stator resistance measurement.
E.co1
Error ! counter overrun 1
54
Counter overflow encoder channel 1.
E.co2
Error ! counter overrun 2
55
Counter overflow encoder channel 2.
E.dOH
Error ! drive overheat
9
Error: Overtemperature of motor PTC. Error can only be reset at E.ndOH,
if PTC is again low-resistance. Causes:
resistance at the terminals T1/T2 >1650 Ohm
motor overloaded
line breakage to the temperature sensor
E.dri
Error ! driver relay
51
Error: Driver relay. Relay for driver voltage on power circuit has not
picked up even though control release was given.
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.
