(9) Adjusting deceleration time
When the deceleration time "td" is significantly different from the acceleration time "ta" (td < 0.95 × ta,
1.1 × 1a < td) and no problem with the acceleration time, adjust the deceleration time by changing
the target value of variable torque limit magnification at deceleration (SP087) setting. In cases,
however, where the variable torque characteristic cannot be lowered to the SP087 level, adjust by
changing the speed for starting change of variable torque limit magnification at deceleration (SP088)
setting.

5-3-3 Adjusting the orientation control
(1) Confirming the default parameters
Set the default parameters for each detector u sed in o rientation control.
(a) Motor PLG
Motor PLG orientation is possible only when the spindle and motor are coupled, or when they
are coupled 1:1 with gears (timing belt). The SP025 (GRA1) to SP032 (GRB4) parameters can
be set only to 1. The PLG with Z-phase must be mounted on the motor to be used.
(b) Spindle end detector
An accurate gear ratio (pulley ratio) is required from
the motor shaft to the spindle end detector rotary
axis.
Make sure that the correct number of gear teeth is
set in SP025 (GRA1) to SP032 (GRB4).
SP025 to SP028=A × C × E
SP029 to SP032=B × D × F
Set the gear ratio (A:X) between the spindle and
