30System Configuration and WiringOverall Wiring (Connecting Example of E-frame)Ground (earth)• Connection with input power supplyBefore turning the power supply on, check whether the input voltage is correct.• Connection to external componentsPB2L1L2L3rtPin P, B1 and B2...B1 and B2 to be kept shorted for nor-mal operation. • When the capacity shortage of theregenerative resister is found, dis-connect a short bar between B1and B2, then connect the externalregenerative resister between Pand B2.Install an external regenerative re-sister on incombustible material,such as metal. Follow the same wir-ing connection as the above. • When you connect an external re-generative resister, set up SV.Pr6Cto 1 or 2.Regenerative resistor (optional)When you use an external regenerative resister,install an external protective apparatus, such asthermal fuse without fail.Thermal fuse and thermostat are built in to theregenerative resistor (Option). If the thermalfuse is activated, it will not resume.Circuit Breaker (NFB)Use the circuit breaker matching capacityof the power source to protect the powerlines.Noise Filter (NF)Prevents external noise from the powerlines. And reduces an effect of the noisegenerated by the servo driver. Magnetic Contactor (MC)Turns on/off the main power of the servodriver.Use a surge absorber together with this.• Never start nor stop the servo motorwith this Magnetic Contactor. Reactor (L)Reduces harmonic current of the mainpower.(see P.32, 33 and 177.)(see P.177 , 178.)(see P.32, 33.)(see P.189.)• Wiring of the Main Circuit (see P.36, 37.)
