Possible Travel Distance for One Command
The range that you can move with one motion command for which a target position is specified
(POSING, EX_POSING, and STEP) is given below.
-2,147,483,648 to 2,147,483,647 MP3000 reference units
 Operation
OL  42 (Zero Point Return Travel Distance) and
OL
 46 (External Positioning Final Travel Distance)
The maximum travel distances that can be used for OL  42 (Zero Point Return Travel Dis-
tance), which is used for ZRET (Zero Point Return), and OL
 46 (External Positioning Final
Travel Distance), which is used for EX_POSING (Latch Target Positioning) and EX_FEED (Jog
Mode with External Positioning), depend on the electronic gear ratio setting, as given in the fol-
lowing table.
The values of OL
 42 and OL  46 depend on the setting of fixed parameter No. 4 (Ref-
erence Unit Selection) as given below.
If the target position is changed while the axis is moving and the travel distance from the current
position exceeds the above range, IL
04 bit 7 (Excessive Positioning Travel Distance) will
turn ON.
