Drive, peripherals, option cards
1 Check drive model number to ensure receipt of correct model. –
2
Make sure you have the correct braking resistors, DC link choke, noise filters, and other peripheral devices
installed.
–
3 Check the option card model number. –
Installation area and physical setup
4 Ensure that the area surrounding the drive complies with specifications. 17
Power supply voltage, output voltage
5 The voltage from the power supply should be within the input voltage specification range of the drive. –
6 The voltage rating for the motor should match the drive output specifications.
15

Main circuit wiring
8 Confirm proper branch circuit protection as specified by national and local codes. 25
9 Properly wire the power supply to drive terminals R/L1, S/L2, and T/L3. 28
10
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.
44
11 Use 600 Vac vinyl-sheathed wire for the power supply and motor lines. 36
12
Use the correct wire gauges for the main circuit. Refer to Wire Gauges and Tightening Torque on page 36 . 36
• Consider the amount of voltage drop when selecting wire gauges. Increase the wire gauge when the voltage
drop is greater than 2% of motor rated voltage. Ensure the wire gauge is suitable for the terminal block. Use
the following formula to calculate the amount of voltage drop:
Line drop voltage (V) = 3
× wire resistance (Ω/km) × wire length (m) × current (A) × 10 -3
36
• If the cable between the drive and motor exceeds 50 m (164 feet), adjust the carrier frequency set to C6-02
accordingly.
45
13 Properly ground the drive. Review page 45 . 45
14
Tightly fasten all terminal screws (control circuit terminals, grounding terminals).
Refer to Wire Gauges and Tightening Torque on page 36 .
36
15
Install a magnetic contactor when using a dynamic braking option. Properly install the resistor and ensure that
overload protection shuts off the power supply using the magnetic contactor.
–
16
Verify phase advancing capacitors, input noise filters, or ground fault circuit interrupters are NOT installed on
the output side of the drive.
–
Control circuit wiring
17 Use twisted-pair line for all drive control circuit wiring. 46
18 Connect the shields of shielded wiring to the ground terminal (E [G] ). 50
19 Properly wire any option cards. 49
20
Check for any other wiring mistakes.
Only use a multimeter to check wiring.
–
21
Properly fasten the control circuit terminal screws in the drive.
Refer to Wire Gauges and Tightening Torque on page 36 .
36
22 Pick up all wire clippings. –
23 Ensure that no frayed wires on the terminal block are touching other terminals or connections. –
24 Properly separate control circuit wiring and main circuit wiring. –
25 Analog signal line wiring should not exceed 50 m (164 ft.). –
26 Safe Disable input wiring should not exceed 30 m (98 ft.). –
