Recommended measures
Carry out a reset; if the error arises repeatedly, replace the
control box
Carry out a reset; if the error arises repeatedly, replace the
control box
Carry out a reset; if the error arises repeatedly, replace the
control box
No valid load
Adjust the curve points of all the actuators
Set the standby position of all the servomotors used
Set the pre-purging position of all the servomotors used
Set the post-purging position of all the servomotors used
Set the ignition position of all the servomotors used
Carry out a reset; if the error arises repeatedly, replace the
control box
No valid load
Adjust the curve points of all the servomotors
Carry out a reset; if the error arises repeatedly, replace the
control box
The reference of the fuel servomotor was not successful.
It was not possible to reach the reference point.
1. Check if the servomotors have been inverted.
2. Check if the servomotor is blocked or overloaded.
The reference of the air servomotor was not successful.
It was not possible to reach the reference point.
1. Check if the servomotors have been inverted.
2. Check if the servomotor is blocked or overloaded.
The parameterisation of an actuator (e.g. the reference
position) has been modified. This error will be visualised to start
up a new reference.
It was not possible to reach the target position within the
requested tolerance range.
1. Check if the servomotor is blocked or overloaded.
Circuit open shown on the servomotor connection.
1. Check the wiring (the voltage between pin 5 or 6 and 2 of the
X54 connector must be > 0.5 V).
The slope of the curve can correspond to a maximum position
modification of 31° between 2 points of the modulation curve.
Overloading of the servomotor or servomotor subjected to
mechanical torsion.
1. Check if the servomotor is blocked in any point along its
range of action.
2. Check if the torque is sufficient for the application.
It was not possible to reach the target position within the
requested tolerance range.
1. Check if the servomotor is blocked or overloaded.
Circuit open shown on the servomotor connection.
1. Check the wiring (the voltage between pin 5 or 6 and 2 of the
X54 connector must be > 0.5 V).
The slope of the curve can correspond to a maximum position
modification of 31° between 2 points of the modulation curve.
