SAFETY PRECAUTIONS
It is mandatory to read the following precautions before
manipulating the STR−ECS640A−GEVB unit.
When connecting an oscilloscope probe to EVB unit the probe’s ground needs to be isolated.
Failure to do so may result in personal injury or death.
STR−ECS640A−GEVB unit contains DC bus capacitors which take time to discharge after removal of the main supply.
Before touching the module, wait ten minutes for capacitors to discharge to safe voltage levels.
Failure to do so may result in personal injury or death.
Only personnel familiar with the drive and associated machinery should plan or implement the installation, start−up and
subsequent maintenance of the system. Failure to comply may result in personal injury and/or equipment damage.
The surfaces of the heat sink may become hot, which may cause injury.
STR−ECS640A−GEVB unit contains parts and assemblies sensitive to Electrostatic Discharge (ESD).
ESD control precautions are required when installing, testing, servicing or repairing this unit’s parts or assemblies.
ESD control procedures not followed may lead to component damage. If you are not familiar with electrostatic control
procedures, refer to applicable ESD protection handbooks and guidelines.
A drive, incorrectly applied or installed, can result in component damage or reduction in product lifetime. Wiring or applica-
tion errors such as under sizing the motor, supplying an incorrect or inadequate AC supply or excessive ambient tempera-
tures may result in system malfunction.
Remove and lock out power from STR−ECS640A−GEVB unit before you disconnect or reconnect wires or perform service.
Wait ten minutes after removing power to discharge the bus capacitors. Do not attempt to service the drive until the bus
capacitors have discharged to zero. Failure to do so may result in personal injury or death.
Voltage doubler configuration is the default STR−ECS640A−GEVB unit configuration and can be used only with 120Vrms
AC input. The use of voltage doubler configuration at 230Vrms AC input may result in personal injury or death.

Thanks for your interest in onsemi
STR−ECS640A−GEVK development platform. Please
follow the instructions below and get access to latest
ECS640A Interface GUI application and evaluation kit
documentation available online in Strata Developer Studio
(Visit
https://www.onsemi.com/design/tools−software/strata−dev
eloper−studio for additional information).
1. STR−ECS640A−GEVB unit is set up for 120Vac AC
mains supply. The EVB unit will be permanently
damaged if connected to a 230Vac AC mains supply.
Please follow the instructions below to set up the
EVB unit for 230Vac supply. If the unit is being
powered with 120Vac you may skip to step 3.
2. The full wave rectification topology needed for
230Vac AC mains supply requires
STR−ECS640A−GEVB hardware configuration
change by following the steps below:
a. Remove C3 (150 mF / 450 V capacitor)
b. Add J7 jumper as indicated in the picture
c. Remove J6 jumper
C3 location
3. Connect USB cable (provided in EVK box) to EVB
J3 connector and laptop USB port. See picture below
for EVB J3 details. EVB LED3 turns on if laptop is
powered on.
4. Connect AC mains power cord Line, Neutral and
Ground signals wire to EVB J1 connector. AC power
cord is not included in EVK box. See picture below
for details. Do not connect power cord to AC mains
outlet at this time.
5. Visit
https://www.onsemi.com/design/tools−software/str
ata−developer−studio to properly set up “Strata
Developer Studio” environment on the laptop. The
“Strata Developer Studio” environment enables
access to up−to−date documentation and latest
ECS640A Interface application to issue BLDC
motor commands.
6. Connect EVB power cord to proper AC mains
voltage (120Vac or 230Vac according to setup
explained in steps 1 and 2 of this Quick Start guide).
Do not touch EVB unit components when energized.
Failure to do so may result in personal injury or
death.
7. EVB LED5 and LED7 will start blinking (~1 second
period) when properly energized and successful
ECS640A boot up sequence.
8. Launch “Strata Developer Studio” application.
Make sure EVB unit is AC mains powered and USB
cable properly connected to laptop to enable
automatic EVB part number identification. A
successful STR−ECS640A−GEVB automatic
identification in Strata Developer Studio is shown
below.

Platform −Quick Start” documentation available at
“Strata Developer Studio” for setting up a new
BLDC motor using ECS640A development
platform.
