Main Circuit Terminal and Motor Wiring
This section outlines the various steps, precautions, and checkpoints for wiring the main circuit terminals and motor terminals.
NOTICE: When connecting the motor to the drive output terminals U/T1, V/T2, and W/T3, the phase order for the drive and motor should
match. Failure to comply with proper wiring practices may cause the motor to run in reverse if the phase order is backward.
NOTICE: Route motor leads U/T1, V/T2, and W/T3 separate from all other leads to reduce possible interference related issues. Failure to
comply may result in abnormal operation of drive and nearby equipment.
n
Ground Wiring
Follow the precautions below when wiring the ground for one drive or a series of drives.
WARNING! Electrical Shock Hazard. Always use a ground wire that complies with technical standards on electrical equipment and minimize
the length of the ground wire. Improper equipment grounding may cause dangerous electrical potentials on equipment chassis, which could
result in death or serious injury.
WARNING! Electrical Shock Hazard. Be sure to ground the drive ground terminal (200 V class: ground to 100 Ω or less; 400 V class: ground
to 10 Ω or less). Improper equipment grounding could result in death or serious injury by contacting ungrounded electrical equipment.
NOTICE: Do not share the ground wire with other devices such as welding machines or large-current electrical equipment. Improper
equipment grounding could result in drive or equipment malfunction due to electrical interference.
NOTICE: When using more than one drive, ground multiple drives according to instructions. Improper equipment grounding could result in
abnormal operation of drive or equipment.
when using multiple drives. Do not loop the ground wire.
