14. USING A LINEAR SERVO MOTOR

14 - 3

14.2 Signals and wiring

WARNING

Any person who is involved in wiring should be fully competent to do the work.

Before wiring, turn off the power and wait for 15 minutes or more until the charge

lamp turns off. Then, confirm that the voltage between P+ and N- is safe with a

voltage tester and others. Otherwise, an electric shock may occur. In addition,

when confirming whether the charge lamp is off or not, always confirm it from the

front of the servo amplifier.

Ground the servo amplifier and the linear servo motor securely.

Do not attempt to wire the servo amplifier and the linear servo motor until they

have been installed. Otherwise, it may cause an electric shock.

The cables should not be damaged, stressed, loaded, or pinched. Otherwise, it

may cause an electric shock.

To avoid an electric shock, insulate the connections of the power supply

terminals.

CAUTION

Wire the equipment correctly and securely. Otherwise, the linear servo motor may

operate unexpectedly, resulting in injury.

Connect cables to the correct terminals. Otherwise, a burst, damage, etc. may

occur.

Ensure that polarity (+/-) is correct. Otherwise, a burst, damage, etc. may occur.

The surge absorbing diode installed to the DC relay for control output should be

fitted in the specified direction. Otherwise, the emergency stop and other

protective circuits may not operate.

Use a noise filter, etc. to minimize the influence of electromagnetic interference.

Electromagnetic interference may be given to the electronic equipment used near

the servo amplifier.

Do not install a power capacitor, surge killer or radio noise filter (FR-BIF option)

with the power wire of the linear servo motor.

When using the regenerative resistor, switch power off with the alarm signal.

Otherwise, a transistor fault or the like may overheat the regenerative resistor,

causing a fire.

Connect the servo amplifier power output (U, V, and W) to the linear servo motor

power input (U, V, and W) directly. Do not let a magnetic contactor, etc. intervene.

Otherwise, it may cause a malfunction.
