Lenze SX-1 - P29: Relative or Absolute Positioning

7.1.2
The defined mode of acceleration is used tor all positioning.
Important notes regarding Sin
2 mode
1. If Sin2 mode is selected, it is not possible to use position instructions with change -
over ot velocity, e. g. PA Vdd V.
2. Change of mode can be performed in a program using Flag F98
(H—Sin2 L=Lin)
3. Acceleration and Deceleration may not be separately defined.
4. DEC function is no longer operative.
ACC defines the number of Scanning Periods tor changing acceleration from zero
to maximum.
ACC = 1 means almost no delay in acceleration
ACC = 100 means maximum delay in acceleration, i. e. 100 x 3 ms = 300 ms
to reach maximum acceleration
In principle, a linear axis is not endless: there is an „End-of-travel“ limit. Rotary movements,
however, can be „Endless“ or „Relative“.
When „Relative“ is selected:
• Only Relative positioning (PR) instructions are accepted.
• Cumulative errors may occur due to „roundina-off errors.
Note:
When using „endless“ mode, chose an Integer value for resolution (Pl). Zero point
correction is not permitted (Pl 1 = 0).
