3.12 Wiring ChecklistNo. Item PageDrive, peripherals, option cards1 Check drive model number to ensure receipt of correct model. 272 Check for correct braking resistors, DC reactors, noise filters, and other peripheral devices. 713 Check for correct option card model. 315Installation area and physical setup4 Ensure area surrounding the drive complies with specifications. 38Power supply voltage, output voltage5 The voltage from the power supply should fall within the input voltage specification range of the drive. 1626 The voltage rating for the motor should match the drive output specifications. 27Main circuit wiring7 Confirm proper branch circuit protection exists per National and Local codes. 488 Properly wire the power supply to drive terminals R/L1, S/L2 and T/L3. 519 Properly wire the drive and motor together.The motor lines and drive output terminals R/T1, V/T2 and W/T3 should match in order to produce the desiredphase order. If the phase order is incorrect, the drive will rotate in the opposite direction. 6010 Use 600 Vac vinyl-sheathed wire for the power supply and motor lines. 5611 Use the correct wire gauges for the main circuit. Refer to Table 3.2, Table 3.3, or Table 3.4. 56• When using comparatively long motor cable, calculate the amount of voltage drop.3 x voltage resistance (Ω/km) x cable length (m) x motor rated current (A) x 10-3Motor rated voltage (V) x 0.02 ≥ 56• If the cable between the drive and motor exceeds 50 m, adjust the carrier frequency (C6-02) accordingly. 6012 Properly ground the drive. 6013 Tightly fasten all terminal screws (control circuit terminals, grounding terminals). Refer to Table 3.2, Table3.3, or Table 3.4. 5614Set up overload protection circuits when running multiple motors from a single drive.M1OL1OL2OLnMC1MC2MCnM2MnDriveMC1 - MCnOL 1 - OL n... magnetic contactor... thermal relayPower supplyNote: Close MC1 through MCn before operating the drive.–15 If using a braking resistor or dynamic braking resistor unit, install a magnetic contactor. Properly install theresistor, and ensure that overload protection shuts off the power supply. 7116 Verify phase advancing capacitors are NOT installed on the output side of the drive. –Control circuit wiring17 Use twisted-pair cables for all drive control circuit wiring. 6218 Ground the shields of shielded wiring to the GND terminal. 6519 If using a 3-Wire sequence, properly set parameters for multi-function contact input terminals S1 through S7,and properly wire control circuits. 5020 Properly wire any option cards. 31521 Check for any other wiring mistakes.Only use a multimeter to check wiring. –22 Properly fasten the control circuit terminal screws in the drive. Refer to Table 3.2, Table 3.3, or Table 3.4. 5623 Pick up all wire clippings. –24 Ensure that no frayed wires on the terminal block are touching other terminals or connections. –25 Properly separate control circuit wiring and main circuit wiring. –26 Analog signal line wiring should not exceed 50 m. –27 Safe Disable Input wiring should not exceed 30 m. –3.12 Wiring ChecklistYASKAWA ELECTRIC SIEP C710606 16C YASKAWA AC Drive – V1000 Technical Manual 733 Electrical Installation
