Overcurrent
trip
If the motor is
restrained or rapidly
accelerated or
decelerated, a large
current flows through
the Inverter, which
results in a
malfunction. The
current exceeding
the specified level
shuts off the output
and an error
appears.
This protection
function detects an
overcurrent through
the AC CT (current
detector).
The protection circuit
is activated at
approximately 220%
of the Inverter rated
output current and a
trip occurs.
Constant
speed
Is there any rapid load fluctuation?
(Eliminate load fluctuation.)
Is there any output short-circuit?
(Check the output wires.)
Is there any ground fault?
(Check the output wires and motor.)
⎯
Deceleration
Is there any rapid deceleration?
(Increase the deceleration time.)
Acceleration
Is there any rapid acceleration?
(Increase the acceleration time.)
Has the motor shaft been locked?
(Check the motor and wires.)
Is the torque boost too high?
(Lower the torque boost.)
Others
Is the DC injection braking too high?
(Lower the injection breaking.)
Is there any error on CT?
(Replace or repair the CT.)
Overload
trip
*1
Monitors the Inverter output current
and shuts off the output, displaying
an error if the built-in electronic
thermal function detects overload
against the motor.
Trips depending on the electronic
thermal function settings.
Is the load too large?
(Reduce the loading factor.)
Is the thermal level correct?
(Adjust the thermal level to an appropriate
level.)
Note: The electronic thermal function is set to
work easily at 5 Hz or lower. If a large
load inertial moment is applied, the
overload protect function works when
the motor starts accelerating, and
prevents it from accelerating. In this
case, increase the torque boost or take
other measures for adjustment.
