========================================
<p>new session of high speed drive tests after issues with Power Supply.</p>

<ul>
	<li>Tests of emergency stop (with a speed at 25% and 43 % GRB speed)&nbsp;with a modification of the jerk value from 0.08 to 0.2 ==&gt; OK</li>
	<li>Tests of azimuth movements : (-90 to 270 degres)
	<ul>
		<li>at 60% of GRB speed. ==&gt; Ok for 6 movements</li>
		<li>at 80% of GRB speed
		<ul>
			<li>Ok for 4&nbsp;movements</li>
			<li>Failures due to resistance&nbsp; (sur-tension). Breaking modules in failure then&nbsp;reset</li>
			<li>Ok for 2 next movements</li>
		</ul>
		</li>
		<li>at 100% of GRB speed :
		<ul>
			<li>3 movements from&nbsp;-90 to 90 ==&gt; OK</li>
			<li>Temperature of breaking resistance are getting very high (at least the top one)&nbsp;</li>
		</ul>
		</li>
	</ul>
	</li>
</ul>
