Note
•
When performing sensorless return-to-home operation upward in a vertical direction with the
EAS4
type, keep the
load mass to be less than 4 kg.
If the load mass is 4 kg or more, the actuator cannot push up to the position of the mechanical stopper, causing
variation in the stopping accuracy of return-to-home.
•
Set the value of the "position offset of home-seeking" to be the following value or larger. If sensorless
return-to-home operation is performed keeping the initial values, the linear slide table becomes a state of contacting
the dedicated stop buffer, causing a negative effect on the stopping accuracy of return-to-home.
・
EAS4
: 2 mm (setting value: 0, moves 200 steps from the actuator end)
・
EAS6
: 5 mm (setting value: 300, moves 500 steps from the actuator end)
