3.12 Wiring Checklist
No. Item Page
Drive, peripherals, option cards
1 Check drive model number to ensure receipt of correct model. 23
2 Check for correct braking resistors, DC reactors, noise filters, and other peripheral devices. 69
Installation area and physical setup
3 Ensure area surrounding the drive complies with specifications. 33
Power supply voltage, output voltage
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. 23
Main circuit wiring
6 Confirm proper branch circuit protection exists per National and Local codes. 43
7 Properly wire the power supply to drive terminals R/L1, S/L2 and T/L3. 46
8
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 phase order. If the
phase order is incorrect, the drive will rotate in the opposite direction.
54
9 Use 600 Vac vinyl-sheathed wire for the power supply and motor lines. 50
10 Use the correct wire gauges for the main circuit. Refer to Table 3.2 through Table 3.4 . 50
• When using comparatively long motor cable, calculate the amount of voltage drop.
3 x voltage resistance (Ω/km) x cable length (m) x motor rated current (A) x 10 -3
Motor rated voltage (V) x 0.02 ≥
50
• If the cable between the drive and motor exceeds 50 m, adjust the carrier frequency
(C6-02) accordingly.
55
11 Properly ground the drive. Review page 55 . 55
12
Tightly fasten all terminal screws (control circuit terminals, grounding terminals). Refer
to Table 3.2 through Table 3.4 ..
