10 Drive Start-Up Procedure
2.
Refer to the following figure and wire the control circuit.
WARNING
or too tight can cause incorrect operation and damage to the drive. Incorrect connections can also cause death or serious
injury from fire.
Note:
• Use shielded, twisted-pair wires and ground the shield to the ground terminal of the drive. Incorrect equipment grounding can
cause drive or equipment malfunction from electrical interference.
• Do not use control circuit wiring that is longer than 50 m (164 ft) to supply the analog frequency reference from a remote source.
If the control circuit wiring is too long, it can cause unsatisfactory system performance.
A - Loosen the screws and put the wire into the
opening on the terminal block.
B - Wire with a crimp ferrule attached, or unsoldered
wire with the core wires lightly twisted
C - Pull back the shielding and lightly twist the end
with your fingers to keep the ends from fraying.
Note:
• Do not solder the core wire. Soldered wiring connections can become loose and cause the drive to malfunction.
• Tighten all terminal screws to the correct tightening torque. Connections that are too loose or too tight can cause incorrect
operation and damage to the drive. Incorrect connections can also cause death or serious injury from fire.
• Refer to
Figure 10.9
for information to prepare terminal ends of the shielded wire.
• Prepare the wire ends of shielded twisted-pair wires as shown in
frequency setting potentiometer to set the frequency. Connect the shield to terminal E (G) of the drive.
A - Connect the shield to terminal E (G) of the drive.
B - Sheath

D - Remove approximately 5.5 mm (0.21 in) of the
covering at the end of the wire when you do not
use crimp ferrules.
E - Blade width of 2.5 mm (0.1 in) or less
F - Blade thickness of 0.4 mm (0.01 in) or less
