The HLP-C100 drive has three different fault types: Warning, alarm and error.
When a fault happens, the drive shows a speci
fi
c code to indicate it.
When a warning happens, it means that the drive is close to its design
limits for some reason, but the drive still works. If the drive fault disappear,
the warning will also disappear.
An alarm means that the drive has exceeded its design limits for some
reason. When this happens, the drive will trip. Af ter an alarm the driver must
be reset in order to re-run. When some alarms happen, the drive will lock itself.
These alarms are called trip-lock alarm. The Trip-lock alarm offers additional
protection, the default setting is that the main power should be cut off before
resetting the alarm. But by setting parameters C14.23 = 0, the trip-lock alarm
can be reset without cutting the main power off. But there is a risk of accident
when choosing this f unction. Before using this f unction, it is important to be
familiar with the drive and the whole system in order to be safe when dealing
with the drive.
Error means that the drive is in a certain state where it is unable to carry
out an operation.
