u Main Circuit Terminal Power Supply and Motor WiringThis section outlines the various steps, precautions, and checkpoints for wiring the main circuitterminals and motor terminals.NOTICE: When connecting the motor to the drive output terminals U/T1, V/T2, and W/T3, the phase orderfor the drive and motor should match. Failure to comply with proper wiring practices may cause the motor torun in reverse if the phase order is backward.NOTICE: Do not connect phase-advancing capacitors or LC/RC noise filters to the output circuits. Improperapplication of noise filters could result in damage to the drive.NOTICE: Do not connect the AC power line to the output motor terminals of the drive. Failure to comply couldresult in death or serious injury by fire as a result of drive damage from line voltage application to outputterminals.n Cable Length Between Drive and MotorWhen the cable length between the drive and the motor is too long (especially at low frequencyoutput), note that the cable voltage drop may cause reduced motor torque. Drive output currentwill increase as the leakage current from the cable increases. An increase in leakage currentmay trigger an overcurrent situation and weaken the accuracy of the current detection.Adjust the drive carrier frequency according to the following table. If the motor wiring distanceexceeds 100 m because of the system configuration, reduce the ground currents.Refer to Table 3.5 to set the carrier frequency to an appropriate level.Table 3.5 Cable Length Between Drive and MotorCable Length 50 m or less 100 m or less Greater than 100 mCarrier Frequency 15 kHz or less 5 kHz or less 2 kHz or lessNote: When setting carrier frequency, calculate the cable length as the total distance of wiring to all connectedmotors when running multiple motors from a single drive.n Ground WiringFollow the precautions to wire the ground for one drive or a series of drives.WARNING! Electrical Shock Hazard. Always use a ground wire that complies with technical standards onelectrical equipment and minimize the length of the ground wire. Improper equipment grounding may causedangerous 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 to100 Ω or less, 400 V Class: Ground to 10 Ω or less). Improper equipment grounding could result in death orserious injury by contacting ungrounded electrical equipment.NOTICE: Do not share the ground wire with other devices such as welding machines or large-current electricalequipment. Improper equipment grounding could result in drive or equipment malfunction due to electricalinterference.NOTICE: When using more than one drive, ground multiple drives according to instructions. Improperequipment grounding could result in abnormal operation of drive or equipment.3.4 Main Circuit Wiring64 YASKAWA ELECTRIC TOEP C710606 47A YASKAWA AC Drive – V1000 Quick Start Guide
