3.12 Wiring Checklist

No.
1 Check drive model number to ensure receipt of correct model.
2 Check for correct braking resistors, DC link chokes, noise filters, and other peripheral devices.
3 Ensure area surrounding the drive complies with specifications.
4 The voltage from the power supply should fall within the input voltage specification range of the drive.
5 The voltage rating for the motor should match the drive output specifications.
6 Confirm proper branch circuit protection exists per National and Local codes.
7 Properly wire the power supply to drive terminals R/L1, S/L2 and T/L3.
Properly wire the drive and motor together. The motor lines and drive output terminals R/T1, V/T2 and W/T3 should
8 match in order to produce the desired phase order. If the phase order is incorrect, the drive will rotate in the opposite
direction.
9 Use 600 Vac vinyl-sheathed wire for the power supply and motor lines.
10 Use the correct wire gauges for the main circuit. Refer to
• When using comparatively long motor cable, calculate the amount of voltage drop.
Motor rated voltage (V) x 0.02 ≥
3 x voltage resistance (Ω/km) x cable length (m) x motor rated current (A) x 10
• If the cable between the drive and motor exceeds 50 m, adjust the carrier frequency (C6-02) accordingly.
11 Properly ground the drive. Review page 41.
Tightly fasten all terminal screws (control circuit terminals, grounding terminals). Refer to
12
3.4..
Set up overload protection circuits when running multiple motors from a single drive.
13
Note: Close MC1 through MCn before operating the drive.
If using a braking resistor or dynamic braking resistor unit, install a magnetic contactor. Properly install the resistor,
14
and ensure that overload protection shuts off the power supply.
15 Verify phase advancing capacitors are NOT installed on the output side of the drive.
16 Use twisted-pair cables for all drive control circuit wiring.
17 Ground the shields of shielded wiring to the GND
If using a 3-Wire sequence, properly set parameters for multi-function contact input terminals S1 through S5, and
18
properly wire control circuits.
19 Check for any other wiring mistakes. Only use a multimeter to check wiring.
20 Properly fasten the control circuit terminal screws in the drive. Refer to
21 Pick up all wire clippings.
22 Ensure that no frayed wires on the terminal block are touching other terminals or connections.
23 Properly separate control circuit wiring and main circuit wiring.
24 Analog signal line wiring should not exceed 50 m.
