This kit contains everything needed for rapid prototyping with the SA310KR 3-phase driver. With a multi- tude of circuit options, the EK76 offers versatility when in comes to connecting inputs, measuring outputs, and conditioning signals to the specific application environment. High- and low- input signals for each phase may be supplied from any 3 V to 18 V digital controller via standard pin header or SMA connectors.
EK76 BEFORE YOU GET STARTED • All Apex Microtechnology amplifiers should be handled using proper ESD precautions. • Always use the heat sink included in this kit. • Always use adequate power supply bypassing. • Do not change the connections while the circuit is powered.
Applications requiring torque control will require the Current Sense gain and off- set circuit described below. Use default values when pairing with the Juno device. Other motor control ICs may be used with EK76, but these may require different wiring and/or current sense circuits.
C1, 2, 3 1 / (2π * f After assembly of the EK76 including the above Current Sense circuit, R22 must be trimmed to reach the desired value of V . To do this, attach a Voltmeter to measure the voltage between pins 11 (negative) and 13 (positive) of P2.
EK76 TEST ASSEMBLY EQUIPMENT NEEDED 1. Power Supplies 2. Digital Controller or 6+ Channel Pattern Generator 3. Oscilloscope 4. Proper Heatsinking System TEST SETUP Make sure all supplies are turned off before connection. Connect the power supplies V (via P15 and P16) and +V (via P1).
