Page
Drive, peripherals, option cards
1
Check drive model number to ensure receipt of correct model.
2
Check for correct braking resistors, DC link chokes, noise filters, and other peripheral devices.
–
Installation area and physical setup
3
Ensure area surrounding the drive complies with specifications.
Power supply voltage, output voltage
4
The voltage from the power supply should fall within the input voltage specification range of the drive.
–
5
The voltage rating for the motor should match the drive output specifications.
Main circuit wiring
6
Confirm proper branch circuit protection exists per National and Local codes.
7
Properly wire the power supply to drive terminals R/L1, S/L2 and T/L3.
–
8
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.
9
Use 600 Vac vinyl-sheathed wire for the power supply and motor lines.
10
Use the correct wire gauges for the main circuit. Refer to
.
When using comparatively long motor cable, calculate the amount of voltage drop.
3 x voltage resistance (Ω/km) x cable length (m) x motor rated current (A) x 10
-3
Motor rated voltage (V) x 0.02 ≥
If the cable between the drive and motor exceeds 50 m, adjust the carrier frequency (C6-02) accordingly.
11
Properly ground the drive.
12
Tightly fasten all terminal screws. Refer to
13
Set up overload protection circuits when running multiple motors from a single drive.

Note: Close MC1 through MCn before operating the drive.
–
14
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.
–
15
Verify phase advancing capacitors are NOT installed on the output side of the drive.
–
Control circuit wiring
16
Use twisted-pair cables for all drive control circuit wiring.
–
17
Ground the shields of shielded wiring to the GND terminal.
18
If using a 3-Wire sequence, set parameters for MFDI terminals S1 through S7, and properly wire control circuits.
19
Check for any other wiring mistakes. Only use a multimeter to check wiring.
–
20
Properly fasten the control circuit terminal screws in the drive. Refer to
21
Pick up all wire clippings.
–
22
Ensure that no frayed wires on the terminal block are touching other terminals or connections.
–
23
Properly separate control circuit wiring and main circuit wiring.
–
24
Analog signal line wiring should not exceed 50 m.
–
25
Safe Disable Input wiring should not exceed 30 m.
