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

....... 4–3

put any conductive object into it. Otherwise, there is a danger of electric

 

shock and/or fire.

 

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

....... 4–3

active, the motor will automatically start and injury may result. Before

 

turning ON the power, confirm that the RUN command is not present.

 

WARNING: When the Stop key function is disabled, pressing the Stop

....... 4–3

key does not stop the inverter, nor will it reset a trip alarm.

 

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

....... 4–3

switch when the application warrants it.

 

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

..... 4–12

active, the motor starts rotation and is dangerous! Before turning power

 

ON, confirm that the Run command is not active.

 

WARNING: After the Reset command is given and the alarm reset

..... 4–24

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

....... 4–2

not to touch them. Otherwise, there is the danger of getting burned.

 

CAUTION: The operation of the inverter can be easily changed from low

....... 4–2

speed to high speed. Be sure check the capability and limitations of the

 

motor and machine before operating the inverter. Otherwise, it may cause

 

injury to personnel.

 

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

....... 4–2

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.

 

CAUTION: It is possible to damage the inverter or other devices if your

....... 4–4

application exceeds the maximum current or voltage characteristics of a

 

connection point.

 

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

....... 4–9

the SR/SK switch position. Otherwise, damage to the inverter circuitry

 

may occur.

 

CAUTION: Be careful not to turn PID Clear ON and reset the integrator

..... 4–28

sum when the inverter is in Run Mode (output to motor is ON). Other-

 

wise, this could cause the motor to decelerate rapidly, resulting in a trip.
