3.13 Wiring ChecklistYASKAWA ELECTRIC SIEP C710616 27C YASKAWA AC Drive A1000 Technical Manual 83Electrical Installation33.13 Wiring ChecklistNo. Item PageDrive, peripherals, option cards1 Check drive model number to ensure receipt of correct model. 312 Make sure you have the correct braking resistors, DC reactors, noise filters, and other peripheral devices. 3753 Check the option card model number. 375Installation area and physical setup4 Ensure that the area surrounding the drive complies with specifications. 40Power supply voltage, output voltage5 The voltage from the power supply should be within the input voltage specification range of the drive. 1946 The voltage rating for the motor should match the drive output specifications. 294447 Verify that the drive is properly sized to run the motor. 29444Main circuit wiring8 Confirm proper branch circuit protection as specified by national and local codes. 549 Properly wire the power supply to drive terminals R/L1, S/L2, and T/L3. 5610Properly 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 desired phase order. If the phase orderis incorrect, the drive will rotate in the opposite direction.7011 Use 600 Vac vinyl-sheathed wire for the power supply and motor lines. 6612Use the correct wire gauges for the main circuit. Refer to Wire Gauges and Tightening Torque on page 66. 66• When using comparatively long motor cable, calculate the amount of voltage drop. 66• If the cable between the drive and motor exceeds 50 m, adjust the carrier frequency set to C6-02 accordingly. 7113 Properly ground the drive. Review page 71. 7114 Tightly fasten all terminal screws (control circuit terminals, grounding terminals).Refer to Wire Gauges and Tightening Torque on page 66. 6615Set up overload protection circuits when running multiple motors from a single drive.Note: Close MC1 through MCn before operating the drive (MC1 through MCn cannot be switched off during run).–16 If using a dynamic braking option, install a magnetic contactor. Properly install the resistor, and ensure that overload protection shuts off thepower supply. 37917 Verify phase advancing capacitors, input noise filters, or ground fault circuit interrupters are NOT installed on the output side of the drive. –Control circuit wiring18 Use twisted-pair line for all drive control circuit wiring. 7219 Ground the shields of shielded wiring to the GND terminal. 7420 If using a 3-wire sequence, properly set parameters for multi-function contact input terminals S1 through S8, and properly wire controlcircuits. –21 Properly wire any option cards. 7422 Check for any other wiring mistakes.Only use a multimeter to check wiring. –23 Properly fasten the control circuit terminal screws in the drive.Refer to Wire Gauges and Tightening Torque on page 66. 6624 Pick up all wire clippings. –25 Ensure that no frayed wires on the terminal block are touching other terminals or connections. –26 Properly separate control circuit wiring and main circuit wiring. –27 Analog signal line wiring should not exceed 50 m. –28 Safe Disable input wiring should not exceed 30 m. –3 x wire resistance (Ω/km) x cable length (m) x motor rated current (A) x 10 -3Motor rated voltage (V) x 0.02 ≥M1OL1OL2OLnMC1MC2MCnM2MnDriveMC1 - MCnOL 1 - OL n... magnetic contactor... thermal relayPower supply
