Err05
Decel
overvoltage
1: The input voltage is too
high.
2: An external force drives the
motor during deceleration.
3: The deceleration time is too
short.
4: The braking unit and
braking resistor are not
installed.
1: Adjust the voltage to
normal range.
2: Cancel the external force
or install the braking resistor.
3: Increase the deceleration
time.
4: Install the braking unit and
braking resistor.
Err06
Constant-speed
overvoltage
1: The input voltage is too high
2: An external force drives the
motor during deceleration.
1: Adjust the voltage to
normal range.
2: Cancel the external force
or install the braking resistor.
Err07
Bus under
voltage

4: The module is faulty.
1: Eliminate external faults.
2: Check whether the motor
Three-phase winding is
normal.
3: Contact the agent or
Frecon.
Err11
Motor overload
