6.8.6 Operating Specifications When Using an MP3000 Con-
troller That Supports the Σ-7-series SERVOPACKs
The operating specifications for combining the MP3000 with a Σ-7-series SERVOPACK are
given in the following sections 1 to 4.
1. 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
2. Restrictions in Deceleration Time during Positioning
The maximum setting of the deceleration time for positioning motion commands (POSING, EX_POS-
ING, ZRET, FEED, STEP, and EX_FEED) depends on the setting of the electronic gear ratio 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 Moving
Amount) will turn ON.
