Error messages of the operating system
ot1: Maximum torque reached [xx.0123.00001]
oC7: Motor overcurrent [xx.0123.00007]
oU: DC bus overvoltage [xx.0123.00014]
LU: DC bus undervoltage [xx.0123.00015]
Response (Lenze setting printed in bold) Setting: C00608 (; Adjustable response)
: 0: No Reaction ; 1: Fault 2: Trouble 3: TroubleQuickStop 4: WarningLocked ; 5: Warning 6: Information
Cause Remedy
The device indicates that the maximally possible torque
at the motor shaft has been reached.
• C00057
displays the current torque.
Reduce motor load.
Response (Lenze setting printed in bold)
0: No Reaction : 1: Fault 2: Trouble 3: TroubleQuickStop 4: WarningLocked 5: Warning 6: Information
Cause Remedy
The maximum current monitoring has tripped.
• The instantaneous value of the motor current has
exceeded the limit value set in C00939
.
Check and, if required, correct dimensioning of the load
with regard to the installed device power.
Response (Lenze setting printed in bold)
0: No Reaction ; 1: Fault : 2: Trouble 3: TroubleQuickStop 4: WarningLocked 5: Warning 6: Information
Cause Remedy
The device has detected an overvoltage in the DC bus. To
protect the device hardware, the inverter control is
switched off.
• Depending on the configuration of the auto-start lock
function, C00142
serves to set that, if this error has
been tripped, the controller only starts after the
controller inhibit is switched.
• If this error message remains active longer than the
time set in C00601
, a "Fault" is tripped.
• Reduce load in generator mode.
• Use a brake resistor.
• Use a regenerative power supply unit.
• Establish a DC-bus connection.
Response (Lenze setting printed in bold) Setting: C00600/1 (; Adjustable response)
0: No Reaction ; 1: Fault : 2: Trouble 3: TroubleQuickStop 4: WarningLocked 5: Warning 6: Information
Cause Remedy
The device has detected a DC bus undervoltage. The
inverter control is switched off because the drive
properties of the motor control cannot be provided
anymore due to the DC bus undervoltage.
• Depending on the configuration of the auto-start lock
function, C00142
serves to set that, if this error has
been tripped, the controller only starts after the
controller inhibit is switched.
• Switch on mains supply or ensure sufficient supply via
DC bus.
• Adjust setting in C00142
if required.
