Deceleratio
n
overvoltage
Err06
1, the input voltage is too high
2. There is external force drag
motor running during
deceleration
3, the deceleration time is too
short
4, no brake unit and brake
resistor installed
1. Adjust the voltage to the
normal range
2, cancel the additional power
or install braking resistor
3, increase the deceleration
time
4, install the brake unit and
resistor

Err07
1, the input voltage is too high
2. There is an external force
drag motor running during the
running process.
1. Adjust the voltage to the
normal range
2, cancel the additional power
or install braking resistor

Inverter
overload
Err10
1. Is the load too large or the
motor is blocked?
2, the inverter selection is too
small
1. Reduce the load and check
the motor and mechanical
conditions.
2, select the inverter with
a larger power level
