WARNING: Be sure not to touch the inside of the energized inverter or to put any

conductive object into it. Otherwise, there is a danger of electric shock and/or fire.

4-3

WARNING: If power is turned ON when the Run command is already active, the

motor will automatically start and injury may result. Before turning ON the power,

confirm that the RUN command is not present.

4-3

4-3

WARNING: When the Stop key function is disabled, pressing the Stop key does not
stop the inverter, nor will it reset a trip alarm.

WARNING: Be sure to provide a separate, hard-wired emergency stop switch when

the application warrants it.

4-3

WARNING: If the power is turned ON and the Run command is already active, the

motor starts rotation and is dangerous! Before turning power ON, confirm that the

Run command is not active.

4-11

WARNING: After the Reset command is given and the alarm reset occurs, the
motor will restart suddenly if the Run command is already active. Be sure to set the

alarm reset after verifying that the Run command is OFF to prevent injury to

personnel.

Cautions for Operations and Monitoring

CAUTION: The heat sink fins will have a high temperature. Be careful not to touch

them. Otherwise, there is the danger of getting burned.

4-2

CAUTION: The operation of the inverter can be easily changed from low speed to
high speed. Be sure to check the capability and limitations of the motor and

machine before operating the inverter. Otherwise, it may cause injury to personnel.

4-2

CAUTION: If you operate a motor at a frequency higher than the inverter standard

default setting (50Hz/60Hz), be sure to check the motor and machine specifications
with the respective manufacturer. Only operate the motor at elevated frequencies

after getting their approval. Otherwise, there is the danger of equipment damage.

4-2

CAUTION: It is possible to damage the inverter or other devices if your application
exceeds the maximum current or voltage characteristics of a connection point.

4-4

CAUTION: Be sure to turn OFF power to the inverter before changing the short

circuit bar position to change SR/SK. Otherwise, damage to the inverter circuitry

may occur.

4-8

CAUTION: Be careful not to turn PID clear ON and reset the integrator sum when

the inverter is in Run mode (output to motor is ON). Otherwise, this could cause the

motor to decelerate rapidly, resulting in a trip.

4-26

HIGH VOLTAGE: When set RDY function ON, there will be a voltage appear at

motor output terminals U, V and W even if the motor is in stop mode. So never

touch the inverter power terminal even the motor is not running.

4-31

HIGH VOLTAGE: Dangerous voltage exists even after the Safe Stop is activated. It
does

NOT mean that the main power has been removed.
