15. USING A LINEAR SERVO MOTOR
15 - 5
15.2 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 (optional FR-BIF-
(H)) 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.
