Development of Multi-axis Servo Amplifier “SANMOTION R” Series
●Introduction
■The AC servo amplifier “SANMOTION R” that went on sale in 2004 has been well received by the market due to its high performance and extensive features. At the same time, it is true that the market is demanding a much smaller servo amplifier with less wiring.
■To respond to such market demands, we developed the multi-axis servo amplifier “SANMOTION R” series that has smaller footprint with less wiring while maintaining the high performance and extensive features of the AC servo amplifier “SANMOTION R”. This document describes the features of this new product.
●Product Overview
■Servo amplifiers are powered by commercial AC source in the same way as standard electrical equipments. They control the position, speed, and torque of servo motors. Their components can be roughly divided into following segment:
▲Converter segment: Converts AC power to DC power.
▲Inverter segment: Converts DC power to AC power.
▲Control circuit segment: Controls the inverter segment.
▲Switching power supply segment: Supplies power to the control circuit segment and peripheral circuitry.
■In a single axis configuration (one servo amplifier connected to one servo motor), each servo amplifier contains all of the segments indicated above. Depending on the machine tool or robot in which it is used, more than one servo amplifier may be used, in which case it is necessary to supply AC power to each servo amplifier and connect each servo amplifier interface to their superior controllers with cables. As a result, there is a limit to the number of the cables and amount of footprint that can be reduced.
■The new servo amplifier system that we developed shares segment , segment, and the interface connection with the superior controller with other amplifiers, enabling reduction in the installation space and wiring. Fig. 1 shows the exterior view of the new servo amplifier.
