Safety Instructions 

Be sure to read this Instruction Manual, SJ700 Instruction Manual, and appended documents thoroughly 

before using EzSQ and the inverter. 

In these Instruction Manuals, safety instructions are classified into two levels: WARNING and CAUTION. 

 

:   Indicates that incorrect handling may cause hazardous situations, which may result in 

serious personal injury or death. 

 

:   Indicates that incorrect handling may cause hazardous situations, which may result in 

moderate or slight personal injury or physical damage alone. 

 

Note that even a                level situation may lead to a serious consequence according to 

circumstances. Be sure to follow every safety instruction, which contains important safety information. 

Also focus on and observe the items and instructions described under "Notes" in the text. 

 

WARNING 

During trial operation of the inverter with a user program, a user program error may cause the motor 
driven by the inverter to run uncontrollably. Be sure to implement safety measures such as the 
emergency stop mechanism in your system before trial operation. Otherwise, system failure or personal 
injury may result. 

 

CAUTION 

To debug a user program, first conduct a trial operation of the inverter with an independent motor to 
confirm that the motor does not run uncontrollably. After that, install the motor in your system (machine), 
and start system operation. Otherwise, system failure or personal injury may result.
