i.2 Using the Product Safely
Conduct test operations to make sure that the drive operates safely after writing work is
completed and parameters have been set.
Failure to comply may cause injury or damage to equipment.
Make sure to confirm the setting values for virtual input and output function parameters before
performing drive test runs.
Virtual input and output functions may have different default settings and operation even though the input and
output terminals are not wired as the drive input and output terminals are virtually wired internally. Using the
drive before confirming these settings and operation may cause injury due to unexpected operation of the drive.
Clear all personnel from the drive, motor, and machine area and secure covers, couplings, shaft
keys, and machine loads before energizing the drive.
Failure to comply could cause death or serious injury if the system starts unexpectedly upon application of
power.
When using DriveWorksEZ to create custom programming, the drive I/O terminal functions
change from factory settings and the drive will not perform as outlined in this manual. Be sure
to check the I/O signals and internal sequence with the engineer who created the DriveWorksEZ
program before attempting operation.
Unpredictable equipment operation may result in death or serious injury.
Do not attempt to modify or alter the drive or drive circuitry in any way not explained in this
manual.
Failure to comply could cause death or serious injury and will void warranty. Yaskawa is not responsible for any
modification of the product made by the user. Do not modify this product.
Only authorized persons qualified in electrical work should perform installation, wiring,
maintenance, inspections, parts replacement, and repairs.
Failure to comply may cause electrical shock.
Do not remove covers or touch circuit boards while the power is on.
Failure to comply could cause death or serious injury.
Do not use the main circuit power supply (Overcurrent Category III) at improper voltages. Before
applying power, make sure the drive rated voltage and the power supply voltage match.
Using the main circuit power supply at improper voltages may result in batteries bursting and igniting, which
could cause fire and injury.
Install adequate branch circuit short circuit protection per applicable codes and this manual.
The drive is suitable for circuits capable of delivering not more than 100,000 RMS symmetrical
amperes, 240 Vac maximum (200 V class), 480 Vac maximum (400 V class).
Failure to comply could cause death or serious injury.
Do not carry the drive by the front cover or terminal cover. Make sure that screws are tightened
properly during transport.
The cover of the drive may come off and the drive may fall if it is carried by the front cover or terminal cover or
if screws are loose, which can result in injury.
