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.

| 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. Unshielded wire can cause electrical interference and unsatisfactory system performance.
