Functional description
Doc ID 16737 Rev 2
21/64
When motor speed is greater than a programmable full step speed threshold, the L6470
switches automatically to full-step mode; the driving mode returns to microstepping when
motor speed decrease below the full step speed threshold. Full step speed threshold is set
through the FS_SPD register (see Section 9.1.9).

Absolute position counter
An internal 22 bit register (ABS_POS) takes memory of motor motion according to the
selected step mode; the stored value unit is equal to the selected step mode (full, half,
6.6
Programmable speed profiles
The user can easily program a customized speed profile defining independently
acceleration, deceleration, maximum and minimum speed values by ACC, DEC,
MAX_SPEED and MIN_SPEED registers respectively (see Section 9.1.5, 9.1.6, 9.1.7 and
9.1.8).
When a command is sent to the device, the integrated logic generates the microstep
frequency profile that performs a motor motion compliant to speed profile boundaries.
All acceleration parameters are expressed in step/tick2 and all speed parameters are
expressed in step/tick; the unit of measure does not depend on selected step mode.
Acceleration and deceleration parameters range from 2-40 to (212-2)2-40 step/tick2
(equivalent to 14.55 to 59590 step/s2).
Minimum speed parameter ranges from 0 to (212-1)2-24 step/tick (equivalent to 0 to 976.3
step/s).
Maximum speed parameter ranges from 2-18 to (210-1) 2-18 step/tick (equivalent to 15.25 to
15610 step/s).
6.6.1
Infinite acceleration/deceleration mode
When ACC register value is set to max (0xFFF), system works in “infinite acceleration
mode”: acceleration and deceleration phases are totally skipped as shown in Figure 6.
It is not possible to skip the acceleration or deceleration phase independently.
