Current Alarm
Drive current exceeded
the level of over current
warning (150% of the
rated current)
1. The load is too heavy
2. Deceleration and
acceleration times are too
short
3.The drive is attempting to
run a motor greater than
the maximum allowable
capacity, or a
special-purpose motor is
being used
4.The current level went up
because of Speed Search
while attempting to perform
a fault restart or after a
momentary power loss
1. Reduce the load or use a drive of
higher rating
2. Calculate the torque required
during acceleration and the inertia
»Take the following steps if the
torque level is not right for the load
· Increase the settings for
acceleration and deceleration time
(C1-00 to C1-07)
· Use a drive of higher rating
3. Check the motor capacity
· Make sure the motor capacity is
right for the drive rating.
4. During a momentary power loss
or an attempt to reset a fault, the
alarm is displayed. However, there
is no need to take any action
because the fault display will
disappear shortly
