SYSDRIVE MX2 Series USER'S MANUAL (3G3MX2-A@@@@)
Description
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.
The Inverter output current is monitored
and if a motor overload is detected by
the built-in electronic thermal, a trip
occurs.
A trip will occur if the usage rate of
regenerative braking circuit exceeds
the b090 set value.
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.

Check point and remedy
code
Constant E01. Is there any rapid load
speed fluctuation?
→Eliminate load
fluctuations.
Is there any output short-circuit?
→Check the output wiring.
Is there any ground fault?
→Check the output
wiring and motor.
During E02. Is there any rapid deceleration?
→Increase the
deceleration
deceleration time.
Acceleration E03. 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. Is the DC injection braking
too high?
→Decrease the braking force.
E05. Is the load too large?
→Decrease the load rate.
Is the thermal level correct?
→Adjust the thermal level
to an appropriate level.
E06. Is there any rapid deceleration?
→Increase the
deceleration time.
Is the operation cycle too short?
→Increase the operation
cycle.
E07. 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.
