HARDWARE B–62545EN/02 2.3.11 Action Against Noise The CNC has been steadily reduced in size using surface–mount and custom LSI technologies for electronic components. The CNC also is designed to be protected from external noise. However, it is difficult to measure the level and frequency of noise quantitatively, and noise has many uncertain factors. Generally, noise is induced in the CNC due to electrostatic coupling, electromagnetic induction, and ground loop. The CNC is equipped with provisions to minimize the influence of extraneous noise. However, it is difficult to quantitatively measure the strength of the noise and how often it occurs. Besides, noise has many unknown elements. To maintain the stability of the CNC machine tool system, it is important to minimize the occurrence of noise and prevent it from being induced into the CNC. When designing the power magnetics cabinet, guard against noise in the machine as described in the following section. (1) Separationg signal lines The cables used for the CNC machine tool are classified as listed in the following table: Process the cables in each group as described in the action column. Group Signal line Primary AC power line Secondary AC power line AC/DC power lines (containing the power lines for the servo and spindle motors) AC/DC solenoid AC/DC relay DC solenoid (24VDC) DC relay (24VDC) Action Bind the cables in g group 1) p A separately p y (Note ( ) from groups g p B and C, or ith an electromagnetic l t ti shield hi ld (N t 2) cover group A with (Note 2). See Section S S i (3) (3)andd connect spark killers k kill or diodes di d with the i h solenoid h l and id relay. d A Connect diodes with DC solenoid and relay. Bind the cables in group B separately from group A, or cover group B with an electromagnetic shield. shield Separate group B as far from Group C as possible. It is more desirable to cover group B with the shield. Bind the cables in group g p C separately p y from group g p A, or cover group g pC with ith an electromagnetic l t ti shield. hi ld S f from f G ibl Separate group C as far Group B as possible. Be sure to perform shield processing in Section (4).

D Use the cable containing the AC power wire and the system ground wire so that power is supplied with the ground wire connected.2. it must have the cross–sectional area of the AC power cable or more. D The grounding resistance of the system ground shall be 100 ohms or less (class 3 grounding). HARDWARE B–62545EN/02 Notes on connecting the ground systems D Connect the signal ground with the frame ground (FG) at only one place in the CNC control unit. D The system ground cable must have enough cross–sectional area to safely carry the accidental current flow into the system ground when an accident such as a short circuit occurs. but cannot suppress the sudden rise of the pulse voltage. D Use a spark killer consisting of a resistor and capacitor in series.) D The reference capacitance and resistance of the spark killer shall conform to the following based on the current (I (A)) and DC resistance of the stationary coil: 1) Resistance (R) : 2) Capacitance (C) Equivalent DC resistance of the coil : I2 10 to I2 20 (mF) Notes on selecting the spark killer I : Current at stationary state of the coil R Equivalent circuit of the spark killer Resistance AC relay Spark killer Condenser C Motor Spark killer Mount the noise eliminator near a motor or a relay coil. NOTE Use a CR–type noise eliminator. FANUC therefore recommends a CR spark killer.B–62545EN/02 2. Varistor–type noise eliminators clamp the peak pulse voltage but cannot suppress a sharp rising edge.(Use it under AC) (A varistor is useful in clamping the peak voltage of the pulse voltage. This pulse voltage induced through the cable causes the electronic circuits to be disturbed. This type of spark killer is called a CR spark killer. A high pulse voltage is caused by coil inductance when these devices are turned on or off. Diode (used for direct–current circuits) + – Diode Use a diode which can withstand a voltage up to two times the applied DC relay voltage and a current up to two times the applied current. 53 .
