DANGER
Do not ignore the safety messages in this manual. If you ignore the safety
messages in this manual, it will cause serious injury or death. The manufacturer is not responsible for
injuries or damage to equipment.
DANGER
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, measure for dangerous voltages to make sure that the drive is safe. If you do work on the drive
when it is energized, it will cause serious injury or death from electrical shock.
WARNING
Crush Hazard. Test the system to make sure that the drive operates safely after
you wire the drive and set parameters. If you do not test the system, it can cause damage to equipment or
serious injury or death.
WARNING
Sudden Movement Hazard. Before you do a test run, make sure that the setting
values for virtual input and output function parameters are correct. Virtual input and output functions can
have different default settings and operation than wired input and output functions. Incorrect function
settings can cause serious injury or death.
WARNING
Sudden Movement Hazard. Remove all personnel and objects from the area
around the drive, motor, and machine and attach covers, couplings, shaft keys, and machine loads before
you energize the drive. If personnel are too close or if there are missing parts, it can cause serious injury
or death.
WARNING
Sudden Movement Hazard. Examine the I/O signals and internal sequence with
the engineer who made the DriveWorksEZ program before you operate the drive. If you do not know how
the drive will operate, it can cause serious injury or death. When you use DriveWorksEZ to make custom
programming, the drive I/O terminal functions change from factory settings and the drive will not operate
as written in this manual.
WARNING
Electrical Shock Hazard. Do not modify the drive body or drive circuitry.
Modifications to drive body and circuitry can cause serious injury or death, will cause damage to the drive,
and will void the warranty. Yaskawa is not responsible for modifications of the product made by the user.
WARNING
Electrical Shock Hazard. Only let approved personnel install, wire, maintain,
examine, replace parts, and repair the drive. If personnel are not approved, it can cause serious injury or
death.
WARNING
Electrical Shock Hazard. Do not remove covers or touch circuit boards while the
drive is energized. If you touch the internal components of an energized drive, it can cause serious injury
or death.
WARNING
Electrical Shock Hazard. After the drive blows a fuse or trips a GFCI, do not
immediately energize the drive or operate peripheral devices. Wait for the time specified on the warning
label at a minimum and make sure that all indicators are OFF. Then check the wiring and peripheral device
ratings to find the cause of the problem. If you do not know the cause of the problem, contact Yaskawa
before you energize the drive or peripheral devices. If you do not fix the problem before you operate the
drive or peripheral devices, it can cause serious injury or death.
