8 YASKAWA TOEPC71061752B GA500 Drive Installation & Primary Operation
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.
WARNING
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.
NOTICE
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 31,000 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.
NOTICE
Use an inverter-duty motor or vector-duty motor with reinforced insulation and windings
applicable for use with an AC drive. If the motor does not have the correct insulation, it can cause a short circuit or
ground fault from insulation deterioration.
NOTICE
Damage to Equipment. When you touch the drive and circuit boards, make sure that you
observe correct electrostatic discharge (ESD) procedures. If you do not follow procedures, it can cause ESD
damage to the drive circuitry.
NOTICE
Damage to Equipment. Do not do a withstand voltage test or use a megohmmeter or
megger insulation tester on the drive. These tests can cause damage to the drive.
NOTICE
Do not operate a drive or connected equipment that has damaged or missing parts. You
can cause damage to the drive and connected equipment.
