3.8 Main Circuit Wiring70 YASKAWA ELECTRIC SIEP C710616 27C YASKAWA AC Drive A1000 Technical Manual◆ Main Circuit Terminal and Motor WiringThis section outlines the various steps, precautions, and checkpoints for wiring the main circuit terminals and motorterminals.NOTICE: When connecting the motor to the drive output terminals U/T1, V/T2, and W/T3, the phase order for the drive and motorshould match. Failure to comply with proper wiring practices may cause the motor to run in reverse if the phase order is backward.NOTICE: Do not connect phase-advancing capacitors or LC/RC noise filters to the output circuits. Failure to comply could result indamage to the drive, phase-advancing capacitors, LC/RC noise filters or ground fault circuit interrupters.NOTICE: Do not connect the AC power line to the output motor terminals of the drive. Failure to comply could result in death or seriousinjury by fire as a result of drive damage from line voltage application to output terminals.■ Cable Length Between Drive and MotorVoltage drop along the motor cable may cause reduced motor torque when the wiring between the drive and the motor istoo long, especially at low frequency output. This can also be a problem when motors are connected in parallel with a4A0208R/L1, S/L2, T/L3 95 35 to 95M10 18 to 23(159 to 204)U/T1, V/T2, W/T3 95 35 to 95–, +1 – 35 to 150+3 – 25 to 7050 50 to 1504A0250R/L1, S/L2, T/L3 120 95 to 300M10 18 to 23(159 to 204)U/T1, V/T2, W/T3 120 95 to 300–, +1 – 70 to 300+3 – 35 to 30070 70 to 2404A0296R/L1, S/L2, T/L3 185 95 to 300M12 32 to 40(283 to 354)U/T1, V/T2, W/T3 185 95 to 300–, +1 – 70 to 300+3 – 35 to 300 M10 18 to 23(159 to 204)95 95 to 240 M12 32 to 40(283 to 354)4A0362R/L1, S/L2, T/L3 240 95 to 300M12 32 to 40(283 to 354)U/T1, V/T2, W/T3 240 95 to 300–, +1 – 95 to 300+3 – 70 to 300 M10 18 to 23(159 to 204)120 120 to 240 M12 32 to 40(283 to 354)4A0414R/L1, S/L2, T/L3 95 × 2P 95 to 150M12 32 to 40(283 to 354)U/T1, V/T2, W/T3 95 × 2P 95 to 150–, +1 – 70 to 150+3 – 70 to 15095 35 to 954A0515R/L1, S/L2, T/L3 120 × 2P 95 to 150M12 32 to 40(283 to 354)U/T1, V/T2, W/T3 150 × 2P 95 to 150–, +1 – 70 to 150+3 – 70 to 150150 50 to 1504A0675R/L1, S/L2, T/L3 95 × 4P 95 to 150M12 32 to 40(283 to 354)U/T1, V/T2, W/T3 95 × 4P 95 to 150–, +1 – 70 to 150+3 – 70 to 15095 × 2P 60 to 150ModelCIMR-A
