Yaskawa V7 Drives - Manual (Page 24)

1-6
The Drive leaves the factory with all parameters set for 2-Wire external reference control. Figure 1-5
must be used for all external connections.
To use the Drive in a 3-Wire application, drive parameters
n001, n003, and n004 must be
reprogrammed, using the Digital Operator. Figure 1-6 must then be used for all external connections.
IMPORTANT
When a cable gland is used for water and dust tight type (NEMA type 4X/12) models, observe the
following:
• Use multi-core cable for cable gland. (If more than one cable is inserted into one cable gland,
a gap is created and may cause leakage.)
• Seal the cable gland with a gasket without fail. (A gasket is attached to the recommended
cable gland.)
A. Main Circuit Input /Output Wiring
Complete wire interconnections according to Table 1-2, Figure 1-5 thru Figure 1-7. Be sure to
observe the following:
• Use 600V vinyl-sheathed wire or equivalent. Wire size and type should be determined by local
electrical codes.
• Avoid routing power wiring near equipment sensitive to electrical noise.
• Avoid running input and output wiring in the same conduit.
• NEVER connect AC main power to output terminals T1(U), T2(V), and T3(W).
• NEVER allow wire leads to contact metal surfaces. Short-circuit may result.
• NEVER connect power factor correction capacitors to the drive output. Consult Yaskawa when
connecting noise filters to the drive output.
• WIRE SIZING MUST BE SUITABLE FOR CLASS I CIRCUITS.
• When connecting motor to drive’s output terminals, include a separate ground wire. Attach
ground wire solidly to motor frame and to drive’s ground terminal .
• When using armored or shielded cable for connection between drive and motor, solidly connect
armor or shield to motor frame, and to drive’s ground terminal .
• Motor lead length should NOT EXCEED 164 feet (50 meters), and motor wiring should be run in
a separate conduit from the power wiring. If lead length must exceed this distance, reduce carrier
frequency (see paragraph 5.8) and consult factory for proper installation procedures.
• Use UL listed closed loop connectors or CSA certified ring connectors sized for the selected wire
gauge. Install connectors using the correct crimp tool recommended by the connector manufacturer.
