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

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.

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
