Fault messages
The BL 4100-C servo drive has an extensive sensor system that monitors the controller
unit, power output stage and motor as well as the communication with the outside world.
Most errors will cause the controller unit to shut down the servo drive and the power output
stage. The power output stage cannot be switched back on until the cause of the error has
been eliminated and the error has been cleared.
If an error occurs, the servo drive will display an error message cyclically by way of its
seven-segment display. The error message consists of the letter E (for error), a main index
and a subindex, e.g.: E 0 1 0. Warnings have the same number as an error message. As a
distinguishing feature, warnings have centre segment before and after the number,
e.g. - 1 7 0 -.
A complete list of events, warnings and error messages can be found in section 15.6
Damage to property caused by errors
In most cases, the drive will be caused to coast down if an error occurs. However, if the
range of movement of the axis is limited, the coast-down may lead to damage to the
machine.
On the other hand, errors of the shaft encoder lead to a quick stop of the drive (even if
there is no information about the commutation position). It is only then that the power
output stage will be switched off.
The operator must check whether the parameterisation of the error responses is correct.
