A circuitbreaker to protect a servo amplifier unit is provided within the servo amplifier This AC line filter should always be used,so influence by harmonic noise to the power supplycan be reduced.

6 When the line voltage is out of specification,and a power transformer (isolationtype) is used, the AC line filter can be omitted. If the AC line filter is ineffective in making the servo amplifier unit satisfy EMC standards, usean appropriate commercial noise The magnetic contactor is required if it is necessary to qualify for European CE When using the SVU,install a surge absorber between the power lines and between a powerline and a ground line at the entrance of the power magnetic cabinet in order to protect theequipment from a surge voltage. For the SVUC, it is unnecessary to install an external surgeabsorber because the SVUC has a built- in surge absorber as the C series CONFIGURATIONB 65195EN/01 START-UP PROCEDURE6(1) SVU 1 ModelOder specificationWiring boardspecificationP.

9 When servo motor accelertes or decelertes rapidly, it may requirepower twice as much as the continuous rating momentarily. Check onthe input voltage required when more than one servo motor accelertesor decelertes simultaneously, and keep the voltage above 170 VAC. Refer to Chapter 5 of SERVO AMPLIFIER UNIT Descriptions (B-65192EN) for details of the power requirements.(3) When motor power and control power are input separately from eachother. When supplying motor power and control power separatelyfrom each other, be sure to remove a jumper connecting L1C and L1,and a jumper connecting L2C and L2. (These jumpers have beenfactory-insatlled.)When it is necessary to make a motor operating with the SVU qualify forEuropean CE marking, ground the motor using the accessory that installing more than one protection ground line with singlescrew makes it impossible for the motor to qualify for European CEmarking.

10 (See Appendix NO TAG.)Because the drive circuit for the servo amplifier unit operates by pulsewidth modulation control system using IGBTs, high-frequency leakagecurrent flows from the motor windings and power lines to the groundthrough stray capacitance. This leakage current may cause the groundfault interrupter or leakage protection relay installed in the power line onthe power supply side to malfunction. So they must have a maesureagainst influence from inverters so tht they do not THEPOWER the LineVoltage and to theProtection Current andSelecting a GroundFault InterrupterB 65195EN/013.
