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.

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.
