Value Meaning
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.3
is written, only the power-circuit dependent parameters are reinitialized.
If any other value is written, then the default set is loaded. On some
systems after writing Sy.3 a Power-On-Reset is necessary.
E.PUCO Error ! Power unit
communication
22
Error: Parameter value could not be written to the power circuit.
Acknowledgement from LT <> 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)
E.SbuS Error ! bus synchron
23
Sychronization over sercos-bus not possible. Programmed response
„Error, restart after reset”.
E.SEt
Error ! set
39
It has been attempted to select a locked parameter set. Programmed
response „Error, restart after reset”.
E.SLF
Error ! Software limit switch
forward
44
The target position lies outside of the limit defined with the right software
limit switch. Programmed response „Error, restart after reset”.
E.SLr
Error ! Software limit switch
reverse
45
The target position lies outside of the limit defined with the left software
limit switch. Programmed response „Error, restart after reset”.
E. UP
Error ! underpotential
2
Error: Undervoltage (DC-link circuit) Occurs, if DC-link voltage falls
below the permissible value. Causes:
input voltage too low or instable
inverter rating too small
voltage losses through wrong cabling
the supply voltage through generator / transformer breaks down at very
short ramps
at F5-G housing B E.UP is also displayed if no communication takes
place between power circuit and control card.
jump factor (Pn.56) too small
if a digital input was programmed as external error input with error
message E.UP (Pn.65).
E.UPh
Error ! Phase failure
3
One phase of the input voltage is missing (ripple-detection)
Warning Messages
A.buS
Warning ! Watchdog
93
Warning: Watchdog for communication between operator/control card
or operator/PC has responded. The response to this warning can be
programmed.
A.dOH
Warning ! drive overheat
96
The motor temperature has exceeded an adjustable warning level.
The switch off time is started. The response to this warning can be
programmed. This warning can be generated only with a special power
circuit.
A. EF
Warning ! external fault
90
This warning is triggered via an external input. The response to this
warning can be programmed.
A.ndOH All-clear ! drive overheat
91
The motor temperature is again below the adjusted warning level. The
switch off time is stopped.
A.nOH
All-clear ! overheat pow.
mod.
88
The heat sink temperature is again below the adjusted warning level.
A.nOHI All-clear ! overheat internal
92
The temperature in the interior of the inverter is again below the warning
threshold.
A.nOL
All-clear ! overload
98
OL counter has reached 0 %, the warning “overload“ can be reset.
A.nOL2 All-clear ! overload 2
101 The cooling time after “Warning ! Overload during standstill" has elapsed.
The warning message can be reset.
A. OH
Warning ! overheat pow.
mod.
89
A level can be defined, when it is exceeded this warning is output. The
response to this warning can be programmed.
