Restrictions in Using Servo Commands
Travel Distance Restrictions for the ZRET (Zero Point
Return) Command
If you use the ZRET (Zero Point Return) command for a
Σ
-7-Series Rotary Servomotor, the fol-
lowing restrictions apply according to the setting of the electronic gear ratio.
Travel Distance Restrictions for the EX_POSING (External
Input Positioning) and EX_FEED (External Input Feed) Com-
mands
If you use the EX_POSING (External Input Positioning) or EX_FEED (External Input Feed) com-
mand for a
Σ
-7-Series Rotary Servomotor, the following restrictions apply according to the set-
ting of the electronic gear ratio.
Travel Distance Restrictions for the TPOS (Target Position)
If you use TPOS (Target Position) for a
Σ
-7-Series Rotary Servomotor, the following restrictions
apply according to the setting of the electronic gear ratio.
Deceleration Time Restrictions during Position Control
If you use a positioning command (i.e., POSING, FEED, EX_FEED, EX_POSING, or ZRET) for a
Σ
-7-Series Rotary Servomotor, the following restrictions apply to the deceleration time.
