</B></U>Release 2.2 (June 2007)</P>
<P>VARBL2 is a very light and highly efficient electronic speed controller for micro brushless motors up to 12g category.</P>

<U><P>Technical data:<br>
</U>Weight (bare board): 1.10g. Wiring may double the weight.<br>
Power supply: 1 to 3 Lipoly  (up to&#9;11V).<br>
BEC: 1A.<br>
Frequency: 12 kHz<br>
Maximum current:  4.5A continuous<br>
Soft start <br>
Number of cells auto detect<br>
Voltage stability control integrated.<br>
Maximum current: optional, disabled by default.<br>
Motor rotation check: optional, disabled by default.<br>
Timing advance optimization.<br>
Zero throttle test.<br>
Configuration selector.<br>
Lipoly low voltage test with motor cut off (disabled by default)</P>
<U><P>Starting with VARBL2:<br></U>

Va, Vb, Vc&nbsp;:  the 3 motor phases<br>
Signal, +5V, Gnd(-)&nbsp;: JST output near receiver (motor function)<br>
Vcc, Clk, Dat&nbsp;: programming pads&nbsp;: don�t solder anything here.</P>
<P><IMG SRC="Image15.gif" WIDTH=419 HEIGHT=319></P>
<P>B+&nbsp;:  Battery  +<br>
Gnd&nbsp;: Battery �<br>
Programming pads:&nbsp;don�t solder anything here.</P>
<P>First turn the transmitter ON. Then connect the VARBL2. If throttle is not at idle, the motor will not start.<br>
Beeps mean: configuration selected, signal received and ready to start. One beep for config. #1, two beeps for config. #2 and so on. Configuration # may be selected by a micro potentiometer. Use a jeweler�s screwdriver�<br>
Starting procedure is ON if propeller is stopped, so you can put the throttle very low for a short time and restart immediatly without any delay if propeller is turning.<br>
If the motor spins the wrong way, invert 2 phases. </P>
<U><P>Troubleshooting:<br>
<UL></U><LI>No beep&nbsp;: check power on, check receiver, lower throttle trim.</LI>
<LI>Stalls at full speed&nbsp;: first stop throttle immediately. Some motors require a high timing advance. Change your configuration.</LI>
<LI>Don�t overload it with too powerful motor.</LI>
<LI>Irregular speed: change your configuration, verify wiring.</LI>
<LI>If motor whistles and propeller stalled, put the throttle low and restart.</LI></UL>
<DIR>
<P>-Most problems are caused by motor wires about to break or incorrect connection/wiring</P>
</DIR>
<B><U><P>VARBL2 Configuration&nbsp;: <br></B></U>
A screw micro potentiometer is mounted on the circuit board.<br>
The screw position allows 5 different configurations. One side of the screw is flat, acting as a pointer (here it points to config #3). Use a jeweler�s screwdriver.</p>
