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. 67
3 Check for correct option card model. 305
Installation area and physical setup
4 Ensure area surrounding the drive complies with specifications. 33
Power supply voltage, output voltage
5 The voltage from the power supply should fall within the input voltage specification range of the drive. 147
6 The voltage rating for the motor should match the drive output specifications. 23
Main circuit wiring
7 Confirm proper branch circuit protection exists per National and Local codes. 48
8 Properly wire the power supply to drive terminals R/L1, S/L2 and T/L3. 50
9
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.
55
10 Use 600 Vac vinyl-sheathed wire for the power supply and motor lines. 53
11
Use the correct wire gauges for the main circuit. Refer to Wire Gauge and Torque Specifications on page 53,
Table 3.3, or Table 3.4.
53
• When using comparatively long motor cable, calculate the amount of voltage drop.
53
• If the cable between the drive and motor exceeds 50 m, adjust the carrier frequency (C6-02) accordingly. 55
12 Properly ground the drive. Review page 56. 56
13
Tightly fasten all terminal screws (control circuit terminals, grounding terminals).
Refer to Wire Gauge and Torque Specifications on page 53, Table 3.3, or Table 3.4.
53
14
Set up overload protection circuits when running multiple motors from a single drive.
Note: Close MC1 through MCn before operating the drive.
-
15
If using a braking resistor or dynamic braking resistor unit, install a magnetic contactor. Properly install the
resistor, and ensure that overload protection shuts off the power supply.
67
16 Verify phase advancing capacitors are NOT installed on the output side of the drive. -
Control circuit wiring
17 Use twisted-pair cables for all drive control circuit wiring. 57
18
Ground the shields of shielded wiring to the GND terminal.
60
19
If using a 3-Wire sequence, properly set parameters for multi-function contact input terminals S1 through S6,
and properly wire control circuits.
49
2
0 Properly wire any option cards. 299
21
Check for any other wiring mistakes.
Onl
y use a multimeter to check wiring.
-
22
Properly fasten the control circuit terminal screws in the drive.
Refer to Wire Gauge and Torque Specifications on page 53, Table 3.3, or Table 3.4.
