3.13 Wiring ChecklistNo. Item Page(s)Drive, Peripherals, Option Cards1 Check drive model number to ensure receipt of correct model. 272 Make sure you have the correct noise filters and other peripheral devices. –3 Check the option card model number. –Installation Area and Physical Setup4 Ensure that the area surrounding the drive complies with specifications. 42Power Supply Voltage, Output Voltage5 The voltage from the power supply should be within the input voltage specification range of the drive. 1346 The voltage rating for the motor should match the drive output specifications. 273307 Verify that the drive is properly sized to run the motor.Main Circuit Wiring8 Confirm proper branch circuit protection as specified by national and local codes. 629 Properly wire the power supply to drive terminals R/L1, S/L2, and T/L3. 6510 Properly wire the drive and motor together.The motor lines and drive output terminals U/T1, V/T2, and W/T3 should match in order to produce the desired phaseorder. If the phase order is incorrect, the drive will rotate in the opposite direction. 8611 Confirm that the crimp terminals are in the correct position. 8212 Use 600 Vac vinyl-sheathed wire for the power supply and motor lines. 8313Use the correct wire gauges for the main circuit.• Consider the amount of voltage drop when selecting wire gauges. Increase the wire gauge when the voltage drop isgreater than 2% of motor rated voltage. Ensure the wire gauge is suitable for the terminal block. Use the followingformula to calculate the amount of voltage drop:Line drop voltage (V) = 3 × wire resistance (Ω/km) × wire length (m) × current (A) × 10-3• If the cable between the drive and motor exceeds 50 m, adjust the carrier frequency set to C6-02 accordingly.8314 For floating, impedance grounded, or asymmetrically grounded networks, disconnect the internal EMC filter by movingthe SW screw to the OFF position. 8815 Properly ground the drive. 8716 Tighten control circuit and grounding terminal screws. 8317Set up overload protection circuits when running multiple motors from a single drive.M1OL1OL2OLnMC1MC2MCnM2MnDriveMC1 - MCnOL 1 - OL n... magnetic contactor... thermal relayPower supplyNote: Close MC1 – MCn before operating the drive. MC1 – MCn cannot be switched off during run.–18 Verify phase advancing capacitors, input noise filters, or GFCIs are NOT installed on the output side of the drive. –Control Circuit Wiring19 Use twisted-pair line for all drive control circuit wiring. 9520 Ground the shields of shielded wiring to the GND terminal. 9521 For 3-Wire sequence, set parameters for multi-function contact input terminals S1 to S7, and wire control circuits. –22 Properly wire the option card. 9523 Check for any other wiring mistakes. Only use a multimeter to check wiring. –24 Properly fasten drive control circuit terminal screws. 8325 Pick up all wire clippings. –26 Ensure that no frayed wires on the terminal block are touching other terminals or connections. –27 Properly separate control circuit wiring and main circuit wiring. –28 Analog signal line wiring should not exceed 50 m. –3.13 Wiring Checklist104 YASKAWA ELECTRIC TOEP C710616 45F YASKAWA AC Drive – Z1000 User Manual
