Description
①
Initial moving direction
Left
Move to the left first.
Right
Move to the right first.
②
Left side condition
None
Do not use left side condition.
End stop
Move to the left to find end stop.
Left limit switch
Move to the left to find limit switch.
③
Right side condition
None
Do not use right side condition.
End stop
Move to the right to find end stop.
Right limit switch
Move to the right to find limit switch.
④
Search end stop current
⑤
Time
The left side and right side conditions can be:
(1) None
(2) End stop
(3) Limit switch
If the left side and right side conditions are end stops, parameters ④ and ⑤ must be set. Parameter ④
is the strength of the force while searching for end stop. Parameter ⑤ is the duration of the force. If
parameter ⑤ is set to be too small, the servo drive may not correctly identify end stop. If parameter ⑤
is set to be too large, error “Soft-thermal threshold reached” could occur. To find proper value, please
refer to the following.
Step 1: Open Scope, as figure 5.6.1.2. Set to observe the value of Actual Current.
Step 2: Let the motor move at slower speed for the total travel distance.
Step 3: Observe the value of Actual Current and record the maximum value, as figure 5.6.1.2. The
maximum value is about 0.2 A, so Search end stop current can be slightly larger than 0.2 A.
In this case, Search end stop current can be set to 0.23 A.
