Hello,  
I have some short distances to move, 20-30 cm between points with zone 50. The TCP’speed I use is 1000 mm but I think it will never reach it. The problem is that the structure on which the robot is attached is vibrating when the robot moves to some points or when it stops. It’s possible to control those vibrations by reducing the accelerations or to use a lower speed? Most of the instructions are MoveJ or MoveAbs and the robot is IRB2600.  
Thank you!

u can use the function AccSet

it is used to reduce the acceleration/deceleration speed and ramp up

start off at 50 max acceleration and 50 ramp

**AccSet 50,50;**
