3.1 Section Safety
NOTICE
Be sure to perform a final check of all sequence wiring and other connections before turning the power on.
Failure to comply could cause erroneous operation or damage the drive.
Make sure there are no short circuits on the control terminals (+V, AC, etc.).
Failure to comply could damage the drive.
Observe proper electrostatic discharge procedures (ESD) when handling the drive and circuit boards.
Failure to comply may result in ESD damage to the drive circuitry.
Never connect or disconnect the motor from the drive while the drive is outputting voltage.
Improper equipment sequencing could result in damage to the drive.
Do not use unshielded cable for control wiring.
Failure to comply may cause electrical interference resulting in poor system performance. Use shielded, twisted-pair
wires and ground the shield to the ground terminal of the drive.
Use ring terminals that comply with UL/cUL for all wire ends.
Failure to comply could result in damage to the drive.
Use only the tools recommended by the terminal manufacturer for crimping.
Failure to comply could result in damage to the drive.
Do not allow unqualified personnel to use the product.
Failure to comply could result in damage to the drive.
Carefully review instruction manual when connecting, wiring, or replacing the drive.
Do not modify the drive circuitry.
Failure to comply could result in damage to the drive and will void warranty.
Yaskawa is not responsible for any modification of the product made by the user. This product must not be modified.
Check all the wiring to ensure that all connections are correct after installing the drive and connecting any other
devices.
Failure to comply could result in damage to the drive.
Comply with proper wiring practices.
The motor may run in reverse if the phase order is backward.
Connect motor input terminals U, V and W to drive output terminals U/T1,V/T2, and W/T3. The phase order for the
drive and motor should match.
