3.4 Mounting 3.4.1 Ocarina 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.
3.5 Integrating the Ocarina and Castanet on a PCB The Oc arin a an d C astan et are designed to be mounted on a PCB, either by soldering its pins directly to the PCB or by using suitable soc ket conne ctors. In both ca ses the following rule s apply: 3.
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 termi nal should be connected to the system's Protective Earth.
3.6.2 Connector J1 Pin # Short Form Function Description 1 EN+ Enable + Positive voltage input of the “Amplifier Enable” function. To enable operation of the amplifier, the optocouple r must be energi zed by applying voltage between this pin (+) and pin J1/22 (-).

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.
4.3.2 Exte rnal Resistor Connect an external resistor between terminal J1/9 (ECLC) and terminal J1/8 (ECLRET). The resistor va lue is given by: 0 < RECLC < 36.4 K (1/8 Watt) At RECLC greater than 36.4 K, the current limit will be internally clamped to the nominal value.
4.3.5 Exte rnal Resistor Connect an external resistor between terminal J1/14 (ECLP) and terminal J1/8 (ECLRET). The resistor va lue is given by: 0 < R ECLP < 36.4 K (1/8 Watt) At RECLP greater than 36.4 K, the current limit will be internally clamped to the nominal value.
