3.13 Wiring ChecklistNo. Item Page(s)Drive, Peripherals, Option Cards1 Check drive model number to ensure receipt of correct model. 252 Make sure you have the correct braking resistors, DC link chokes, 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. 38Power Supply Voltage, Output Voltage5 The voltage from the power supply should be within the input voltage specification range of the drive. 1286 The voltage rating for the motor should match the drive output specifications. 253157 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. 709 Properly wire the power supply to drive terminals R/L1, S/L2, and T/L3. 7310 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. 8411 Use 600 Vac vinyl-sheathed wire for the power supply and motor lines. 8112Use the correct wire gauges for the main circuit. Refer to Main Circuit Wire Gauges and Tightening Torque on page81.• 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.818413 Properly ground the drive. Review page 84. 8414 Tighten control circuit and grounding terminal screws. Refer to Main Circuit Wire Gauges and Tightening Torque onpage 81. 8115Set 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.–16 Install a magnetic contactor when using a dynamic braking option. Properly install the resistor and ensure that overloadprotection shuts off the power supply using the magnetic contactor. –17 Verify phase advancing capacitors, input noise filters, or GFCIs are NOT installed on the output side of the drive. –Control Circuit Wiring18 Use twisted-pair line for all drive control circuit wiring. 8919 Ground the shields of shielded wiring to the GND terminal. 8920 For 3-Wire sequence, set parameters for multi-function contact input terminals S1 – S7, and wire control circuits. –21 Properly wire any option cards. 8922 Check for any other wiring mistakes. Only use a multimeter to check wiring. –23 Properly fasten drive control circuit terminal screws. Refer to Main Circuit Wire Gauges and Tightening Torque onpage 81. 8124 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. –3.13 Wiring ChecklistYASKAWA TOEP YAIZ1U 03B YASKAWA AC Drive – Z1000 User Manual 973 Electrical Installation
