3. Setup
In the case of the semi-closed loop control
Set the same value as SV020 (RNG2). (Refer to the explanation of
SV020.)
In the case of the full-closed loop control
Set the number of pulses per ball screw pitch.

Set the detection time constant of Overload 1 (Alarm 50).
Set to "60" as a standard. (For machine tool builder adjustment.)
Set the current detection level of Overload 1 (Alarm 50) in respect to the
stall (rated) current.
Set to "150" as a standard. (For machine tool builder adjustment.)
Set the excessive error detection width when servo ON.
<Standard
setting value> OD1=OD2=
When "0" is set, the excessive error detection will not be performed.
Set the in-position detection width.
Set the accuracy required for the machine.
The lower the setting is, the higher the positioning accuracy gets, however,
the cycle time (setting time) becomes longer. The standard setting is "50".
