TOEPYAIGA8002B GA800 Drive Programming
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.
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
Figure 4.24 Wiring Procedure for the Control Circuit
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
for information to prepare terminal ends of the shielded wire.
• Prepare the wire ends of shielded twisted-pair wires as shown in
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.
A - Connect the shield to terminal E (G)
of the drive.
B - Sheath
C - Insulate with electrical tape or
shrink tubing.
