Overcurrent
protection
If the motor is restrained or
rapidly accelerated or
decelerated, a large current
will flow through the Inverter,
which will result in breakage.
Accordingly, the protection
circuit operates at
approximately 200% of the
Inverter rated output current
and a trip occurs.
Constant
speed
E01.
îš…
Is there any rapid load
fluctuation?
→
Eliminate load fluctuation.
Is there any output short-circuit?
→
Check the output wiring.
Is there any ground fault?
→Check the output
wiring and motor.

îš…
Is there any rapid deceleration?
→Increase the
deceleration time.

Acceleration
E03.
îš…
Is there any rapid acceleration?
→Increase the
acceleration time.
Has the motor been locked?
→Check the motor and
wiring.
Is the torque boost too high?
→
Lower the torque boost.
Others E04.
îš…
Is the DC injection braking
too high?
→
Decrease the braking force.
5-135
Overload
protection
*1
The Inverter output current is monitored
and if a motor overload is detected by
the built-in electronic thermal, a trip
occurs.
E05.
îš…
Is the load too large?
→Decrease the load rate.
Is the thermal level correct?
→Adjust the thermal level
to an appropriate level.

Braking
resistor
overload
protection
A trip will occur if the usage rate of
regenerative braking circuit exceeds
the b090 set value.
E06.
îš…
Is there any rapid deceleration?
→Increase the
deceleration time.
Is the operation cycle too short?
→Increase the operation
cycle.

Overvoltage
protection
Extremely high DC voltage between P/
+2 and N/− may result in
failure.Accordingly, a trip will occur if
the DC voltage between P/+2 and N/−
reaches approx. 400 VDC (200V class)
or 800 VDC (400V class) or above due
to increase in the regenerative energy
from the motor or in the incoming
voltage.
E07.
îš…
Is there any rapid deceleration?
→Increase the
deceleration time.
Is there any ground fault?
→Check the output
wiring and motor.
Has the motor been rotated
from the load side?
→Reduce regenerative
energy.
Has incoming voltage
increased?
→
Lower the incoming
voltage, sustain the power
supply fluctuation, apply
the AC reactor to input.

*1. The reset command will not be accepted until approximately 10 seconds pass since the trip occurs
(protection function works).
