P6
8.2.5 Spindle Indexing at Constant Acceleration
Spindles
With spindle indexing, when bit 5 of words N1 to N4 of P6 is a 1, the positioning speed is at constant deceleration.
The deceleration is expressed in deg/s 2 in parameter P32 (see 6.4).
The limit speed P43 is expressed in rpm.
The in-position window P44 is expressed in internal measurement units.
The servo-loop gain P45 is expressed in rpm/rev. It is only used at the end of positioning when deceleration at constant
«gamma» is requested.
