Pr. 399 Orientation deceleration ratio (initial value is 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.
Pr. 351 Orientation speed (initial value: 2Hz)
• Set the speed when switching beween the speed control mode and the position control mode is performed under
orientation operation.
Decreasing the set speed enables stable orientation stop. Note that the orientation time will increase.

CAUTION
Or, if the motor does forward/reverse reciprocation operation , the parameter setting value for the orientation detector
installation direction may be incorrect. Review Pr. 393 Orientation selection (refer to page 212) and Pr. 359 Encoder rotation direction
(refer to page 211) .
REMARKS
When "19" is set in Pr. 52 DU/PU main display data selection , position pulse monitor is displayed instead of PU output voltage
monitor.
REMARKS
1. :Increase the parameter setting value.
:Do not change the parameter setting
value.
:Decrease the parameter setting value.
2. The numbers 1) , 2) and 3) in the table show
the order of priority for changing the
parameters setting value.
