60 YASKAWA TOEPC71061752B GA500 Drive Installation & Primary Operation
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.
D - When you do not use crimp
ferrules, remove
approximately 5.5 mm (0.21
in) of the covering at the end
of the wire.
E - Blade width of 2.5 mm (0.1
in) or less
F - Blade thickness of 0.4 mm
(0.01 in) or less
Figure 8.11 Wiring Procedure for the Control Circuit
Note:
• It is easier to wire TB1-1 first, then TB1-2, then TB1-3.
• 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 8.12 for information to prepare terminal ends of the shielded wire.
• Prepare the wire ends of shielded twisted-pair wires as shown in Figure 8.12 to use an analog reference
from an external frequency setting potentiometer to set the frequency. Connect the shield to terminal E (G)
of the drive.
