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.
If you do work on the drive when it is
energized, it will cause serious injury or death
from electrical shock.

DANGER
|
|
|
Electrical Shock Hazard
Disconnect all power to the drive and wait for
the time specified on the warning label before
you remove covers. Check the drive for dangerous
voltages before servicing or repair work.
If you do work on the drive when it is energized
and there is no cover over the electronic
circuits, it will cause serious injury or death
from electrical shock. The drive has internal
capacitors that stay charged after you
de-energize the drive.

|
Warning
|
|
|
Electrical Shock Hazard
The motor will run after you de-energize the
drive. PM motors can generate induced voltage to
the terminal of the motor after you de-energize
the drive.
If you touch a motor that is moving or
energized, it can cause serious injury or death.

|
Warning
|
|
|
Electrical Shock Hazard
Do not operate the drive when covers are
missing. Replace covers and shields before you
operate the drive. Use the drive only as
specified by the instructions.
Some figures in this section include drives
without covers or safety shields to more clearly
show the inside of the drive. If covers or
safety shields are missing from the drive, it
can cause serious injury or death.
|
|
Warning
|
|
|
Electrical Shock Hazard
Always ground the motor-side grounding terminal.
If you do not ground the equipment correctly, it
can cause serious injury or death if you touch
the motor case.
|
|
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 wear loose clothing or jewelry when you
do work on the drive. Tighten loose clothing and
remove all metal objects, for example watches or
rings.
Loose clothing can catch on the drive and
jewelry can conduct electricity and cause
serious injury or death.
|
|
Warning
|
|
|
Fire Hazard
Tighten all terminal screws to the correct
tightening torque.
Connections that are too loose or too tight can
cause incorrect operation and damage to the
drive. Incorrect connections can also cause
death or serious injury from fire.
|
|
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.
|
|
Warning
|
|
|
Fire Hazard
Do not put flammable or combustible materials on
top of the drive and do not install the drive
near flammable or combustible materials. Attach
the drive to metal or other noncombustible
material.
Flammable and combustible materials can start a
fire and cause serious injury or death.
|
|
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
|
|
|
Sudden Movement Hazard
Make sure that you align the phase order for the
drive and motor when you connect the motor to
drive output terminals U/T1, V/T2, and W/T3.
If the phase order is incorrect, it can cause
the motor to run in reverse. If the motor
accidentally runs in reverse, it can cause
serious injury or death.
|
|
CAUTION
|
|
|
Burn Hazard
Do not touch a hot drive heatsink. De-energize
the drive, wait for a minimum of 15 minutes,
then make sure that the heatsink is cool before
you replace the cooling fans.
If you touch a hot drive heatsink, it can burn
you.
|
|
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
|
|
|
Use the instructions in this manual to replace
the cooling fans. When you do maintenance on the
fans, replace all the fans to increase product
life.
If you install the fans incorrectly, it can
cause damage to the drive.
|
|
Notice
|
|
|
Make sure that all connections are correct after
you install the drive and connect peripheral
devices.
Incorrect connections can cause damage to the
drive.
|
|
Notice
|
|
|
Damage to Equipment
Do not energize and de-energize the drive more
frequently than one time each 30 minutes.
If you frequently energize and de-energize the
drive, it can cause drive failure.
|
|
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.
|
Note:
Do not use unshielded cable for control wiring. Use
shielded, twisted-pair wires and ground the shield to
the ground terminal of the drive. Incorrect wiring can
cause electrical interference and unsatisfactory system
performance.
