 None  System fault  Fault  Trouble  Quick stop by trouble  Warning locked  Warning  Information
Cause Remedy
Master current is in the impermissible range -4 ... +4 mA,
e.g. due to a cable break or a defective master current
value encoder.
• Only for parameterisation as master current input
(see C00034 ).
Remove open circuit.

Cause Remedy
Communication between regenerative power supply
module and extension module is interrupted, e.g. due to
disturbances in the environment (EMC), defective
hardware, or loose contact.
• This monitoring function is intended for safe
communication via process data.
• Eliminate EMC disturbances.
• Switch off regenerative power supply module, insert
extension module correctly, and switch on the
regenerative power supply module again.
• Mains switching, or restart of regenerative power
supply module.
• Replace extension module/regenerative power
supply module.
• Please contact Lenze if the problem occurs again.

 None  System fault  Fault  Trouble  Quick stop by trouble  Warning locked  Warning  Information
Cause Remedy
It is not possible to establish communication between
the regenerative power supply module and the
extension module in the MXI1 module slot.
• Switch off regenerative power supply module, insert
extension module correctly in module slot MXI1, and
switch on the regenerative power supply module
again.
• If the problem occurs again, replace the extension
module.
