Diagnostic messages and fault clearance
19h
Real time error LM-CPU
Definable as:
F
/-/-
Diagnostic memory: optional
The LM-CPU requires more computation time than is available to it.
Check whether multiple connections have been established to the device. If yes, terminate the
unneeded connections. Further remedial measures: Do without trace drawings, reduce bus load
– Resettable: Error can be reset immediately.
Definable error response(s): A,
B
1Ah
Intermediate circuit voltage exceeded
Definable 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 is defective.
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.
– Acknowledgeability: Error can only be acknowledged after eliminating the cause.
Definable error response(s): A,
B
1Bh
Intermediate circuit voltage too low
Definable as:
F
/W/-
Diagnostic memory: optional
The load voltage is too low.
Voltage drops under load: power supply unit too weak, supply line too long, cross section too
small?
If you intentionally want to operate the device with a lower voltage, parameterise this malfunction
as a warning or information.
Measure load voltage (directly at the controller input).
– For parameterisation as an error: The error can only be acknowledged after the cause is elimin
ated.
Definable error reaction(s):
A
– For parameterisation as a warning: The warning disappears if the load voltage is back within the
permissible range.
22h
Homing
Definable as:
F
/-/-
Diagnostic memory: optional
Homing run to switch unsuccessful. A corresponding switch has not been found.
Check to make sure the correct homing method is set.
Check to see if the homing switch is connected and if it has been parameterised correctly (nor
mally closed contact/normally open contact?). Check the functionality of the switch and check the
cable for wire breaks.
If the error is still present, it means there is an internal defect and the device has to be replaced.
– Resettable: Error can be reset immediately.
Definable error response(s):
B
, C, E, F
