14. Set overtravel limits according to the maximum speed of the servo drive system and the
payload of the application.
You can determine the deceleration distance before the piston rod contacts the end of
travel based on the deceleration rate of the load, and the peak force available from the
motor/screw combination. Use
Motion Analyzer software to calculate the minimum
deceleration distance at the maximum speed of your application.
Tune Your Electric Cylinder
1. Open the MotionView Onboard software.
2. Disable the motor.
3. From the Drive Organizer, choose General.
4. From the Drive Mode pull-down menu, choose Autotune.
5. Enable the motor.
6. From the Drive Organizer, choose Dynamics.
7. Click Autotune.
IMPORTANT Set travel limits and direction of tuning moves in reference to the piston rod starting
position. Leave adequate travel for the piston rod to complete its moves while
tuning.
ATTENTION: Software overtravel must be set prior to initiating the tuning process.
Check the starting position of the piston rod and allow for adequate travel.
Insufficient travel while auto tuning causes the software overtravel to trigger an
end-stop impact.
ATTENTION: Care must be taken to not exceed the physical travel limits of the electric
cylinder. Doing so causes the electric cylinder to reach the mechanical end-of-stroke.
Impacting the mechanical end-of-stroke can physically damage the screw and internal
components of the electric cylinder.
IMPORTANT A positive-direction move command denotes a rod extend operation; a
negative-direction move command denotes a retract operation.
