Drive, Peripherals, Option Cards
1
Check drive model number to ensure receipt of correct model.
11
2
Make sure you have the correct noise filters and other 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.
13
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.
11
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.
19
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.
27
11
Confirm that the crimp terminals are in the correct position.
22
12
Use 600 Vac vinyl-sheathed wire for the power supply and motor lines.
23
13
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:
Line drop voltage (V) = 3 × wire resistance (Ω/km) × wire length (m) × current (A) × 10
-3
• If the cable between the drive and motor exceeds 50 m, adjust the carrier frequency set to C6-02 accordingly.
23
14
For floating, impedance grounded, or asymmetrically grounded networks, disconnect the internal EMC filter by
moving the SW screw to the OFF position.
37
15
Properly ground the drive.
–
16
Tighten control circuit and grounding terminal screws.
