Drive, Peripherals, Option Cards
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.
–
Installation Area and Physical Setup
4
Ensure that the area surrounding the drive complies with specifications.
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.
7
Verify that the drive is properly sized to run the motor.
Main Circuit Wiring
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.
10
Properly wire the drive and motor together.
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.
11
Use 600 Vac vinyl-sheathed wire for the power supply and motor lines.
12
Use the correct wire gauges for the main circuit.
Refer to Main Circuit Wire Gauges and Tightening Torque on page
.
• 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

• 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.
