Chapter 2: Introduction

This Installation Guide is intended for design engineers who are integrating an Elmo

Motion Control Ocarina and Castanet servo amplifiers into a machine.

The Ocarina and Castanet series of servo-amplifiers was designed to deliver “the highest

possible power density”. The Ocarina can deliver up to 1.4 kW of continuous power or

2.8 kW of peak power in a matchbox size (2.25 in³ or 38cc) package. The Castanet delivers

up to 240 W of continuous power or 480 W of peak power.

The Ocarina and Castanet are designed for OEMs. They operate from a DC power source in

current mode in conjunction with a DC Brush and Brushless motors (refer to section 4.1).

The Ocarina and Castanet can operate as a stand-alone device.

There are two categories of Ocarinas and Castanets, 60 VDC versions and 100 VDC

versions. Power to the 60 V products is provided by a separate 0 ~ 59 V isolated DC

power source. Power to the 100 V products is provided by a separate 0 ~ 95 V isolated

DC power source.

Note: There is a separate VL terminal for the control/logic supply input. In the 60 VDC

models this terminal can be connected to an external 11 ~ 59 VDC isolated supply. In the

100 VDC models this terminal can be connected to an external 12 ~ 95 VDC isolated

supply whenever the user wants to control the logic supply with an auxiliary low power

voltage source.

If power separation is not needed the VL and VP+ terminals can be shorted so that the

main power supply will also power the control/logic supply and there will be no need

for a separate control/logic supply.

The Ocarina and Castanet are PCB mounted devices which enable efficient and cost

saving implementation.
