 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.

 0: No Reaction  1: Fault  2: Trouble  3: TroubleQuickStop  4: WarningLocked  5: Warning  6: Information
Cause Remedy
Maximum current monitoring has tripped. 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, set C00142 so that, when this error is
tripped, the controller only restarts after the
controller inhibit has been 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, set C00142 so that, when this error is
tripped, the controller only restarts after the
controller inhibit has been switched.
• Switch on mains supply or ensure sufficient supply via
DC bus.
• Adjust setting in C00142 if required.
