3.10 Wiring ChecklistNo. Item Page(s)Drive, Peripherals, Option Cards1 Check drive model number to ensure receipt of correct model. 222 Make sure you have the correct braking resistors, DC reactors, 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. 28Power Supply Voltage, Output Voltage5 The voltage from the power supply should be within the input voltage specification range of the drive. 996 The voltage rating for the motor should match the drive output specifications. 222277 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. 389Properly wire the power supply to drive terminals R/L1, S/L2, and T/L3.Note: Confirm the following when wiring models CIMR-Ao4A0930 and 4A1200:• Remove the jumpers shorting terminals R/L1-R1/L11, S/L2-S1/L21, and T/L3-T1/L31 when operatingwith 12-phase rectification.• When operating without 12-phase rectification, properly wire terminals R1/L11, S1/L21, and T1/L31 inaddition to terminals R/L1, S/L2, and T/L3.4110 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 desired phaseorder. If the phase order is incorrect, the drive will rotate in the opposite direction. 5911 Use 600 Vac vinyl-sheathed wire for the power supply and motor lines. 5212Use the correct wire gauges for the main circuit. Refer to Wire Gauges and Tightening Torque on page 52.• 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.525913 Properly ground the drive. Review page 59. 5914 Tighten control circuit and grounding terminal screws. Refer to Wire Gauges and Tightening Torque on page 52. 5215Set 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. 6419 Ground the shields of shielded wiring to the GND terminal. 6420 For 3-Wire sequence, set parameters for multi-function contact input terminals S1 – S8, and wire control circuits. –21 Properly wire any option cards. 6422 Check for any other wiring mistakes. Only use a multimeter to check wiring. –23 Properly fasten drive control circuit terminal screws. Refer to Wire Gauges and Tightening Torque on page 52. 5224 Pick up all wire clippings. –3.10 Wiring ChecklistYASKAWA ELECTRIC TOEP C710616 41B YASKAWA AC Drive - A1000 Quick Start Guide 713 Electrical Installation
