to obey these safety messages can cause serious injury, death, or damage to the products and related equipment and systems.
These identifier words categorize and emphasize important safety precautions in these instructions.
DANGER Identifies a hazardous situation, which, if not avoided, will cause death or serious injury.
WARNING Identifies a hazardous situation, which, if not avoided, can cause death or serious injury.
CAUTION Identifies a hazardous situation, which, if not avoided, can cause minor or moderate injury.
NOTICE Identifies a property damage message.
■General Safety
General Precautions
•The diagrams in this manual may include options and drives without covers and safety shields to more clearly show what is inside the
drive. Put back all covers and shields before operation. Use options and drives only as indicated in the instructions described in this
manual.
•The diagrams in this manual are provided as examples only. They may not pertain to all products covered by this manual.
•The products and specifications described in this manual and the content may be changed without notice to improve the product and/or
the manual.
•In the event that this manual becomes damaged or gets lost, contact a Yaskawa representative or the nearest Yaskawa sales office shown
on the rear cover of the manual, and inform them of the document number on the front cover to order new copies.
DANGER Do not ignore the safety messages in this manual. The operating company is responsible for injuries or
equipment damage caused from ignoring the messages in this manual. Failure to obey the safety messages will cause death or
serious injury.Electrical Shock Hazard. Do not examine, connect, or disconnect wiring on an energized drive. Before servicing,
disconnect all power to the equipment and wait for the time specified on the warning label at a minimum. The internal capacitor
stays charged after the drive is de-energized. The charge indicator LED extinguishes when the DC bus voltage decreases
below 50 Vdc. When all indicators are OFF, remove the covers before measuring for dangerous voltages to make sure that the
drive is safe. Failure to obey will cause death or serious injury.
WARNING Crash Hazard. Test the system to make sure that the drive operates safely after you wire the drive and set
parameters. Failure to obey can cause injury or damage to equipment.Sudden Movement Hazard. Make sure that the setting
values for virtual input and output function parameters are correct before a test run. Virtual input and output functions can have
different default settings and operation. Failure to obey can cause injury or death.Sudden Movement Hazard. Remove all
persons and objects from the area around the drive, motor, and machine area and attach covers, couplings, shaft keys, and
machine loads before energizing the drive. Failure to obey can cause death or serious injury.Electrical Shock Hazard. Do not
make changes to the drive body or drive circuitry. Failure to obey can cause death or serious injury and will void warranty.
Yaskawa is not responsible for changes to the product made by the user.Electrical Shock Hazard. Only let authorized persons
install, wire, maintain, examine, replace parts, and repair the drive. Failure to obey can cause death or serious injury.Electrical
Shock Hazard. Do not remove covers or touch circuit boards while the drive is energized. Failure to obey can cause death or
serious injury.Fire Hazard. Do not use the main circuit power supply (Overcurrent Category III) at incorrect voltages. Make sure
that the drive rated voltage aligns with the power supply voltage before energizing the drive. Failure to obey can cause death or
serious injury.Fire Hazard. Install sufficient branch circuit short circuit protection as specified by applicable codes and this
manual. The drive is suited for circuits that supply not more than 100,000 RMS symmetrical amperes, 240 Vac maximum (200 V
Class), 480 Vac maximum (400 V Class). Failure to obey can cause death or serious injury.
CAUTION Crush Hazard. Do not hold the drive by the front cover or terminal cover. Tighten the screws correctly before
moving the drive. Failure to obey can cause minor to moderate injury.
NOTICE Use a motor that provides insulation correct for PWM drives. Failure to obey can cause a short circuit or
ground fault from insulation deterioration.Observe correct electrostatic discharge (ESD) procedures when touching the drive
and circuit boards. Failure to obey can cause ESD damage to the drive circuitry.Do not do a withstand voltage test or Megger
test on the drive. Failure to obey can cause damage to the drive.Do not connect or operate damaged equipment or equipment
with missing parts. Failure to obey can cause damage to the drive and connected equipment.Do not immediately energize the
drive or operate peripheral devices after the drive blows a fuse or trips an ELCB. Then check the wiring and peripheral device
ratings to find the cause of the problem. Contact Yaskawa before energizing the drive or peripheral devices if the cause is not
known. Failure to obey can cause death or serious injury and damage to the drive. Failure to obey can cause death or serious
injury and damage to the drive.If it is necessary to use disinfectant or to debug wood material for packaging, use a method other
than steam. Example: Heat treatment (core at 56 °C [133 °F] or higher for more than 30 minutes) Gas steam from fumigated
wooden packaging materials can cause damage to electrical components. Halogen disinfectants (fluorine, chlorine, bromine,
and iodine) erode capacitors, and DOP gas (phthalic acid ester) cracks resin materials. Do all treatment procedures before
packaging components.
