Infinite acceleration/deceleration mode
When the ACC register value is set to max. (0xFFF), the system works in “infinite
acceleration mode”: acceleration and deceleration phases are totally skipped, as shown in
Figure
It is not possible to skip the acceleration or deceleration phase independently.

Motor control commands
The L6472 can accept different types of commands:
●
●
●
●
For detailed command descriptions refer to
Constant speed commands
A constant speed command produces a motion in order to reach and maintain a user
defined target speed starting from the programmed minimum speed (set in the MIN_SPEED
register) and with the programmed acceleration/deceleration value (set in the ACC and DEC
registers). A new constant speed command can be requested anytime.
constant speed commands (Run, GoUntil, ReleaseSW)
absolute positioning commands (GoTo, GoTo_DIR, GoHome, GoMark)
motion commands (Move)
stop commands (SoftStop, HardStop, SoftHiz, HardHiz).
