i.2 Using the Product Safely
16 YASKAWA SIEPC71061737B GA800 Drive Technical Reference
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.
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.
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.
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.
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.
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.
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.
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.
Damage to Equipment
Do not apply incorrect voltage to the main circuit of the drive. Operate the drive in the specified
range of the input voltage on the drive nameplate.
Voltages that are higher than the permitted nameplate tolerance can cause damage to the drive.
Fire Hazard
Install sufficient branch circuit short circuit protection as specified by applicable codes and this
manual. The drive is suitable for circuits that supply not more than 100,000 RMS symmetrical
amperes, 240 Vac maximum (200 V Class), 480 Vac maximum (400 V Class).
Incorrect branch circuit short circuit protection can cause serious injury or death.
CAUTION
Crush Hazard
Tighten terminal cover screws and hold the case safely when you move the drive.
If the drive or covers fall, it can cause moderate injury.
