POSITIONING MODULE REPLACEMENT
(2) Changed function from AD75P1-S3/P2-S3/P3-S3
In case of using the following functions with AD75P-S3, make sure that there is no operation problems
when converted to QD75PN/QD75DN.
Changed functions
1. The limit check of arc address is carried out only when a sub point is designated.
2. The software stroke limit check during speed control is carried out in the following cases:
• When the software stroke limit is applied to the current feed value with
• When the software stroke limit is applied to the machine feed value
3. If an attempt is made to change the current value but the designated address is out of the software stroke

There are 3 types of errors for each upper and lower stroke limit.

QD75PN/QD75DN:
Errors for the software stroke upper limit are integrated in to error code 507.
Errors for the lower limit are integrated in to error code 508.

If the reference axis operates in reverse direction, the control is internally changed into the continuous
positioning control. (restart after deceleration stop)
Even if the reference axis operates in reverse direction with interpolation, the control remains as the
continuous path control.
(In single-axis operation, the operation is the same as that of the AD75P-S3.)
