Type of error/diagnostic memory
Error name
Dec
17
23
Logic voltage exceeded
(Logic voltage exceeded)
Can be parameterised as:
F
/-/-
Diagnostic memory: optional
The logic power supply monitor has detected an overvoltage. This is either due to an internal defect
or an excessive supply voltage.
Check external supply voltage directly on the device.
If the error is still present after a reset has been conducted, it means there is an internal defect
and the device has to be replaced.
–
Acknowledgement option: Error can be acknowledged.
Parameterisable error response(s): A,
B
18
24
Logic voltage too low
(Logic voltage too low)
Can be parameterised as:
F
/-/-
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 reset. If it is, 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
19
25
Temperature LM-CPU
(Temperature LM-CPU)
Can be parameterised as:
F
/-/-
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
1O
26
Intermediate circuit voltage exceeded
(Intermediate circuit voltage exceeded)
Can be parameterised as:
F
/-/-
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.
In the event of a defective internal braking resistor: Replace the controller.
–
Acknowledgement option: Error can be acknowledged.
Parameterisable error response(s): A,
B
