During operation of VFD, the acceleration rate of motor speed may be lower than
the increasing rate of output frequency due to heavy loads in some cases, and it
will result in fault “over-current when acceleration” and VFD trigging with no
measure being carried out.
The principle of auto current limiting is as following: By sensing VFD output
current and comparing to FA.06 which defining the current limiting point, if the
output current is over the point, VFD will decrease output frequency in the rate
value of FA.07, and will return to normal operation until the output current falling
to lower than the current limiting point. As shown in the following illustration.
