1 PREFACEThis manual provides information necessary for maintenance of theFANUC Control MotorAmplifier series ( servo amplifier units SVU and SVUC).There are two servo amplifier unit types, as listed ** The specification of this type is partly differentfrom that of the C series servo amplifier. Conforms to ** This type is designed to satisfy the compatibility with the C series servo amplifier. Does not conform to I describes the procedure to start up the servo amplifier unit. Part IIdescribes the error recovery procedure.

2 Part III describes the cautions that should be observed in switching fromthe C series servo amplifier to the series servo amplifier unit SVU or document uses the abbreviations listed **SVUA06B-6090-H**SVUCFANUC Series FS- Fanuc Power Mate MODEL PM- In this manual, the servo parameter numbers are arranged as shown Function name or bit of the servo parameter No. 1877 Overload protection coefficient (OVC1) FS-16, 18, 20, 21PM-D, F FS-0 CNo. 8X62No. 2062In addition to this manual, those listed below are provided for the FANUCC ontrol Motor Amplifier series ( servo amplifier unit).

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.

9 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.

10 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.
