(2) Power supply capacity
The power supply capacity required for each servo amplifier is as follows. The same power supply
capacity applies to the step-up or step-down transformer.
The specified power supply capacity is for the designated cable size and a wiring length of 20m. If the
power supply capacity is 500 kVA or more, an AC reactor specified in section 10-6 should be provided.
(Otherwise the contact of the electromagnetic contactor or the like may melt.)

The RYB Series servo amplifier (3-phase 200V type 3.7 kW or less) is applicable to the harmonics
suppression guideline for electric appliances and general-purpose equipment (enacted in 1994 and
revised in September 1997) issued by the Ministry of International Trade and Industry of Japanese
government. Regulation levels are determined by the Japan Electrical Manufacturers’ Association
according to this guideline.
You must connect a reactor for harmonics suppression to the servo amplifier to comply with this
guideline. Refer to “AC reactor” in the manual for the reactor.
When you prepare the other reactor, consult us for its detailed specifications.
