2.
Click the Homing tab.
3.
Set parameters for either absolute homing or torque level-to-marker homing as shown on
this table.
4.
Complete these steps for absolute homing.
a. Use motion direct commands to slowly jog your axis to your application's home
location, being sure to not exceed 10 mm/s (0.4 in/s).
b. Issue the Motion Direct Command (MAH) to set the home position on your axis.
5.
Click the Limits tab.
6.
Enter these parameters.

ATTENTION: Avoid excessive force while homing the electric cylinder. Do not exceed
10 mm/s (0.4 in/s) during a home routine.
Speeds greater than 10 mm/s (0.4 in/s) may damage the electric cylinder when the
piston rod reaches the end of travel.

Hard Travel Limits
Check if hardware limits are in use. Use the
software to determine the
maximum stopping distance in your application to set negative and positive limits.
Soft Travel Limits
Check if software limits are in use. Use the
software to determine the
maximum stopping distance in your application to set negative and positive limits.
Maximum Positive
Enter value that is within the piston-rod mechanical travel.
Maximum Negative
Enter value that is within the piston-rod mechanical travel.
