Ocarina/Castanet Installation Guide
Introduction
MAN-OCSIG (Ver. 1.2)
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.
2.1
Product Description
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.

3.4.1
Ocarina
Installation
3-3
The Ocarina was designed for mounting on a printed circuit board (PCB). It is connected by
2 mm pitch 0.51 mm square pins. When designing the Ocarina into a device, be sure to leave
about 1 cm (0.4") outward from the heatsink to enable free air convection around the Ocarina.
We recommend that the Ocarina be soldered directly to the board. Alternatively, the Ocarina
can be attached to socket connectors mounted on the PCB. If the PCB is enclosed in a metal
chassis, we recommend that the Ocarina be screw-mounted to it as well to help with heat
dissipation. The Ocarina has screw-mount holes on each corner of the heatsink for this purpose.
3.4.2
Castanet
The Castanet was designed for mounting on a printed circuit board (PCB). It is connected by
2mm pitch 0.51 mm square pins. When designing the Castanet into a device, be sure to leave
about 1 cm (0.4") outward from the lower board to enable free air convection around the
Castanet. We recommend that the Castanet be soldered directly to the board. Alternatively, the
Castanet can be attached to socket connectors mounted on the PCB.
Note: Elmo recommends you leave approximately 1 cm (0.4 in) of space on the side opposite
the terminals to allow for free air convection.

Integrating the Ocarina and Castanet on a PCB
The Ocarina and Castanet are designed to be mounted on a PCB, either by soldering its pins
directly to the PCB or by using suitable socket connectors. In both cases the following rules
apply:
3.5.1
Traces
1. The size of the traces on the PCB (thickness and width) is determined by the current
carrying capacity required by the application.
The rated continuous current limit (Ic)of the Ocarina and Castanet is the current
used for sizing the motor traces (M1, M2, M3 and PE) and power traces (VP+, PR
and PE).
For control, feedbacks and inputs/outputs conductors the actual current is very
small but “generous” thickness and width of the conductors will contribute to a
better performance and lower interferences.
2. The traces should be as short as possible to minimize EMI and to minimize the heat
generated by the conductors.
3. The spacing between the high voltage conductors (VP+, PR, M1, M2, M3, VL) must be
at least:
Surface layer:
1.5
mm
Internal layer:
0.10
mm
Complying with the rules above will help satisfy UL safety standards, MIL-STD-275 and the
IPC-D-275 standard for non-coated conductors, operating at voltages lower than 100 VDC
and at “unlimited altitudes” (above 10,000 meters – 30,000 feet).
3.5.2
Grounds and Returns
The “Returns” of the Ocarina and Castanet are structured internally in a star configuration.
The returns in each functional block are listed below:
Functional Block
Return Pin
Power
PR (Power Return)
Internal Switch Mode P.S.
PR (Power Return)
Control section
Internal, not accessible
Feedback
SUPRET (J2/2)
The returns above are all shorted within the Ocarina and Castanet in a topology that results in
optimum performance.
1. When wiring the traces of the above functions, on the Integration Board, the returns of
each function must be wired separately to its designated terminal on the Ocarina and
Castanet. DO NOT USE A COMMON GROUND PLANE. Shorting the commons on the
Integration Board may cause performance degradation (ground loops, etc).
2. Return Traces: The return traces should be as large as possible, but without shorting
each other, and with minimal cross-overs.
3. Main Power Supply and Motor Traces: The power traces must be kept as far away as
possible from the feedback and control traces.
Ocarina/Castanet Installation Guide
Installation
MAN-OCSIG (Ver. 1.2)
3-5
4. PE Terminal: The PE terminal is connected directly to the Ocarina's heatsink or to the
Castanet's two PE strips on its lower board. In the Ocarina, the heatsink serves as an EMI
common plane. The PE terminal should be connected to the system's Protective Earth.
Any other metallic parts (such as the chassis) of the assembly should be connected to the
Protective Earth as well.
5. Under normal operating conditions, the PE trace carries no current. The only time these
traces carry current is under abnormal conditions (such as when the device has become a
potential shock or fire hazard while conducting external EMI interferences directly to
ground). When connected properly the PE trace prevents these hazards from affecting
the drive.
Follow these instructions to ensure safe and proper implementation.
Failure to meet any of the above-mentioned requirements can result in
drive/controller/host failure.

DC Power Supply
The DC power supply can be at any voltage in the range defined in the technical
specifications (the Appendix of this guide). The supply source must comply with the safety
aspects of the relevant requirements, in accordance with the most recent version of the
standard EN60950 or equivalent Low Voltage Directive Standard, all according to the
applicable over-voltage category. If the power source to the power supply is the AC line
(through an isolated transformer), safety margins must be considered, in order to avoid
activating the under/over voltage protection due to line variations and/or voltage drop
under load.
In addition to the above, the transformer must comply with the safety aspects of the relevant
requirements in accordance with the most recent version of the standard EN60742 (Isolating
and Safety Isolating Transformers). The nominal DC bus voltage should be in the following
range:
1.2 Vdcmin < Vdc < 0.9 Vdcmax
where:
Vdcmin is the minimum DC bus
Vdcmax is the maximum DC bus
The recommended minimum power supply capacitance for a single-phase rectified DC source
connection is as follows:
Amplifier Voltage Range
60 V
100 V
Recommended capacitance
≥ 470 µF
≥470 µF
The transformer power should be calculated such that it will be able to deliver power to the
amplifier (including peak power) without significant voltage drops.
The power supply should be located as close as possible to the amplifier. The maximum
distance is 30 cm (1 foot). While driving high-inertia loads, the power supply must be
equipped with a shunt regulator; otherwise, the amplifier will be disabled whenever the
capacitors are charged above the maximum voltage, during motor break down.

3.11.1.3 How to Use the Charts
The charts above are based upon theoretical worst-case conditions. Actual test results show
30% - 50% better power dissipation.
To determine if your application needs a heatsink:
1. Allow maximum heatsink temperature to be 80 °C or less.
2. Determine the ambient operating temperature of the Ocarina.
3. Calculate the allowable temperature increase as follows:
•
for an ambient temperature of 40 °C , ∆T= 80 °C – 40 °C = 40 °C
4. Use the chart to find the actual dissipation power of the drive. Follow the voltage
curve to the desired output current and then find the dissipated power.
5. If the dissipated power is below 4W the Ocarina will need no additional cooling.
Note: The chart above shows that no heatsink is needed when the heatsink temperature is
80 °C, ambient temperature is 40 °C and heat dissipated is 4 W.
3.11.2
Castanet
The best way to dissipate heat from the Castanet is to mount it so that its lower board faces
upwards. For best results leave approximately 10 mm of space between the Castanet's lower
board and any other assembly.

Chapter 4: Servo Control Operation
4.1
Ocarina/Castanet Connected to DC Motors
In order to connect the Ocarina or Castanet to a DC motor, connect Hall A (J1 pin 4 of the
drive) to Hall return (J1 pin 17 of the drive). The motor should be connected to M2, M3.
4.2
Current Command Input
The Ocarina and Castanet have a single differential input. The input operating voltage range
is ± 3.75 V, meaning that a 3.75 V signal will result in a fully rated peak current. The current
limit circuits will override this signal if the peak duration exceeds 2.7 seconds and/or the
required current exceeds the values set by the ECLC and ECLP signals. If the input command
voltage exceeds 3.75 V, input scaling must be implemented by adding a pair of external
resistors, according to the following formula:
Rin (kΩ) = (5.33 * Vin) - 20
Be careful not to apply input voltage above the maximum allowed input voltage as this will
cause the input operational amplifier to operate beyond its limits (±20 V) and in extreme
cases, may even damage it.
4.3
External Current Limit - Continuous (ECLC)
The continuous current limit of the Ocarina and Castanet amplifiers can be scaled down by an
external voltage or by an external resistor connected from pin J1/9 (ECLC) to pin J1/8
(ECLRET).
4.3.1
External Voltage
IC(new) =
VECLC
3.75V
* Ic(nom)
An external positive voltage (0 to 3.75 V) to terminal J1/9 (ECLC) in reference to terminal J1/8
(ECLRET) will control the continuous current limit from zero to Ic (nom).
The voltage is internally clamped to 3.75 V whenever the external VECLC is greater than
3.75V.
The external voltage source must be able to source/ sink at least ±0.2 mA.
The maximum absolute VECLC allowed to be connected is 5 V.

At RECLC greater than 36.4 K, the current limit will be internally clamped to the nominal
value.
IC(nom) is the nominal continuous current limit of the amplifier.
4.3.3
External Current Limit - Peak (ECLP)
The peak current limit of the Ocarina and Castanet amplifiers can be scaled down by an
external voltage or by an external resistor connected between pin J1/14 (ECLP) and J1/8
(ECLRET).
4.3.4
External Voltage
An external positive voltage (0 to 3.75 V) to terminal J1/14 (ECLP) in reference to terminal
J1/8 (ECLRET) will control the peak current limit from zero to Ip(nom).

IP(nom) is the nominal peak current limit of the amplifier.
4.3.6
Latch Mode (LM)
By connecting J1/7 to J1/15, the amplifier is latched to disable mode whenever a Short,
Commutation or Over Temperature failure occurs. Disabling the amplifier temporarily by
removing the power from Enable pin J1/1 resets the latch. Be sure to restore the Enable
connection when the reason for the event no longer exists.

Table 4-1: Ocarina/Castanet Status Indications
Notes:
Without latch mode:
The status indications are reset when the fault disappears.
With latch mode:
The Short, Over Temperature and Commutation Failure status indications are reset
when the enable signal is temporarily removed from the enable input.
Multiple faults:
Only the reading of the first fault is reliable. Additional faults add on to the status
outputs and the indication is therefore meaningless.
