Over-voltage at stop
Over-voltage at
accel
Over-voltage at
constant speed
Over-voltage at
decel
1: Extend the Ramp-down Time or add a
braking resistor.
2: Improve the mains supply voltage and check
whether there is any sudden change in the
voltage.
E.Lu.s

E.Lu.d
Low voltage
1: Check whether the input voltage is normal.
2: Check whether there is sudden change in
load.
3: Check whether there is any phase missing.
E.OH.S
E.OH.A
E.OH.n
E.OH.d
Overheat of
inverter
1: Check whether the fan is blocked and
whether there is any foreign matter stuck in
the cooling fins.
2: Check whether the ambient temperature is
normal.
3: Check whether there is enough space for
ventilation and good air convection.

E.OL.n
E.OL.d
Inverter overload
150% Per minute
1: Check whether the capacity of the inverter is
lower. Otherwise it should be increased.
2: Check whether there is any jamming in the
mechanical load.
3: The setting of V/F curve is bad. Set it again.
E.OA.A
E.OA.n
E.OA.d
Motor overload
150% Per minute
1: Check whether there is any sudden change in
the mechanical load.
2: The equipped motor is too small.
3: The motor is hot and the insulation becomes
bad.
4: Check whether the voltage has big
fluctuation.
5: Check whether there is any phase missing.
6: The mechanical load is increased.
E.OT.A
E.OT.n
E.OT.d
Motor over-torque
1: Check whether there is any fluctuation in the
mechanical load.
2: Check whether the equipped motor is smaller.
