Display COMBIVIS Value Meaning
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 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
The speed is outside the defined limits. (can also occur on exceeding
of the absolute speed referring to EMF = EMF wrong (servo drives).
E.PFC Error ! PFC 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 ! power circuit unknown 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; the error can be
reset by writing on SY.03 at valid power circuit. If the value displayed
in SY.03 is written, only the power-circuit dependent parameters
are reinitialized. If any other value is written, then the default set is
loaded. A power-on-reset is necessary on some systems after writing
of SY.03.
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 circuit coding 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.SCL
ERROR! speed controller
limit
25 Speed controller limit reached
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”.
