Table of error messages
18h Logic voltage too low Can be parameterised as: E/-/-
Diagnostic memory: optional
The logic power supply monitor has detected an undervoltage. This is either due to an internal defect
or an overload/short circuit caused by connected peripherals.
• Separate device from the entire peripheral equipment and check whether the error is still present
after a reset. If so, it means there is an internal defect and the device has to be replaced.
– Acknowledgement option: Cannot be acknowledged, software reset required.
Parameterisable error response(s): A
19h Temperature LM-CPU Can be parameterised as: E/-/-
Diagnostic memory: optional
The monitor has detected a CPU temperature outside the permissible range.
• Check whether the ambient temperature is within the permissible range for the controller. If the
error is still present, it means there is an internal defect and the device must be replaced.
• The error can only be acknowledged if the temperature is within the permissible range.
– Acknowledgement option: Error can be acknowledged.
Parameterisable error response(s): A, B
1Ah Intermediate circuit voltage exceeded Can be parameterised as: E/-/-
Diagnostic memory: always
Load voltage not within the permissible range.
Braking resistor is overloaded; too much braking energy which cannot be dissipated quickly enough.
Braking resistor defective or not connected.
• Check the load voltage; measure voltage directly at the controller input.
• Check cylinder sizing: Braking resistor overloaded?
• In the event of a defective internal braking resistor: Replace the controller.
– Acknowledgement option: Error can be acknowledged.
Parameterisable error response(s): A, B
1Bh Intermediate circuit voltage too low Can be parameterised as: E/W/-
Diagnostic memory: optional
Load voltage too low.
• Voltage drops under load: power supply unit too weak, supply line too long, cross section too
small?
• Measure load voltage (directly at the controller input).
• If you intentionally want to operate the device with a lower voltage, parameterise this malfunction
as a warning or information.
– For parameterisation as an error: The error can be acknowledged.
Parameterisable error response(s): A
– For parameterisation as a warning: The warning disappears if the load voltage is back within the
permissible range.
