Prohibited
 Never touch the internal connector while the upper terminal cover of control panel is
opened.
There is a risk of electrical shock because it carries a high voltage.

Do not touch inverter terminals when electrical power is going to the inverter even if the
motor is stopped.
Touching the inverter terminals while power is connected to it may result in electric shock.

Do not touch switches when the hands are wet and do not try to clean the inverter with a
damp cloth.
Such practices may result in electric shock.

Do not go near the motor in alarm-stop status when the retry function is selected.
The motor may suddenly restart and that could result in injury.
Take measures for safety, e.g. attaching a cover to the motor, against accidents when the
motor unexpectedly restarts.

action
 Turn the input power on only after attaching the terminal block cover.
When enclosed inside a cabinet and used with the terminal block cover removed, always
close the cabinet doors first and then turn the power on. If the power is turned on with the
terminal block cover or cabinet doors open may result in electric shock.

Make sure that operation signals are off before resetting the inverter after malfunction.
If the inverter is reset before turning off the operating signal, the motor may restart
suddenly, resulting in injury.

If incorrect setting, the drive may has some damage or unexpected movement. Be sure to
set the setup menu correctly.

Prohibited

Observe all permissible operating ranges of motors and mechanical equipment. (Refer to
the motor's instruction manual.)
Not observing these ranges may result in injury.

Do not set the stall prevention level (

) extremely low.
If the stall prevention level parameter (

) is set at or below the no-load current of
the motor, the stall preventive function will be always active and increase the frequency
when it judges that regenerative braking is taking place.
Do not set the stall prevention level parameter (

) below 30% under normal use
conditions.
