No.
1 Check drive model number to ensure receipt of correct model.
2 Make sure you have the correct peripheral devices.
3 Check the option card model number.
4 Ensure that the area surrounding the drive complies with specifications.
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.
7 Verify that the drive is properly sized to run the motor.
8 Confirm proper branch circuit protection as specified by national and local codes.
9 Properly wire the power supply to drive terminals R/L1, S/L2, and T/L3.
Properly wire the drive and motor together.
10 The motor lines and drive output terminals U/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.
Use 600 Vac vinyl-sheathed wire for the power supply and motor lines. Wire gauge recommendations based on using
11
75 °C (167 °F), 600 Vac vinyl-sheathed wire.
Use the correct wire gauges for the main circuit.
• 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:
12
Line drop voltage (V) = 3 × wire resistance (Ω/km) × wire length (m) × current (A) × 10
• If the cable between the drive and motor exceeds 50 m, adjust the carrier frequency set to C6-02 accordingly.
13 Properly ground the drive.
14 Tighten control circuit and grounding terminal screws.
15 Verify phase advancing capacitors, input noise filters, or GFCIs are NOT installed on the output side of the drive.
16 Use twisted-pair line for all drive control circuit wiring.
17
Ground the shields of shielded wiring to the GND
18 For 3-Wire sequence, set parameters for multi-function contact input terminals S1 – S8, and wire control circuits.
19 Properly wire any option cards.
20 Check for any other wiring mistakes. Only use a multimeter to check wiring.
21 Properly fasten drive control circuit terminal screws.
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.).
