CHAPTER 2 WIRING
2.1.2 Configuration
The figure on page 2-7 shows the general configuration of devices. There is no need to connect
all devices.
The size on each device in the figure is not drawn at the uniform scale (same as other chapters).
To supply single-phase power to the servo amplifier, use the L1 and L2 terminals.
The servo amplifier wiring connector is attached only to TB2 on the frames 2 and 3. It is not
provided for other devices.
2
Use a connector kit or optional cable with a connector.
Adopt a configuration for turning the main power off upon alarm detection (activation of protective
function of servo amplifier).
Otherwise overheat of the regenerative resistor, such as regenerative resistor transistor failure
may cause fire.
The maximum wiring length between the servo amplifier and servomotor is 50 m.
You may not turn the power wiring of the servo amplifier or servomotor on or off with a contactor
or you may not drive multiple servomotors selectively with a single servo amplifier.
Do not connect any of the following devices to the power wiring of the servo amplifier or
servomotor.
・Phase advancing capacitor ・Various reactors ・Noise filter ・Surge absorber
Be sure to ground the protective grounding terminal of the servo amplifier (terminal provided with
a grounding mark) to the protective ground of the control panel to avoid electric shock.
Use the accessory tool in the following procedure to connect the terminal to TB1, TB2 and TB3.
Wiring method
<Frame 1, 2, 3>
[1] Peel off the sheath about 10 mm.
10[mm]
[2] Insert the tip of the accessory tool into the top of the connector.
[3] Push the tool toward the connector to insert the cable.
[4] Release the tool. The cable is fixed.
Do not solder the cable. In case of the strand wire, do not twist cable forcibly.
