Pr. 399 "orientation deceleration ratio" (factory setting: 20)
• Make adjustments as shown below according to the orientation status.
(Refer to the Pr. 396 and Pr. 397 details also.)
Generally adjust Pr. 362 in the range from 5 to 20 and Pr. 399 from 5 to 50.
Phenomenon
Rocking occurs during
stopping
The orientation time is long
Hunting occurs when
stopping
The servo rigidity during
stopping is low
CAUTION
If orientation stop is not possible and the excessive position error alarm occurs, or if the motor does
forward/reverse reciprocation operation
installation direction may be incorrect. Review Pr. 393
852 encoder rotation direction
"
Pr. 351 orientation switchover speed
"
Set the speed when switching beween the speed control mode and the position control mode under orientation
operation. Decreasing the set speed enables stable orientation stop. Note that the orientation time will increase.
