Any attempt to write to the register when the motor is running causes the command to be
ignored and the NOTPERF_CMD to rise (see paragraph 9.1.22).
9.1.9
FS_SPD
The FS_SPD register contains the threshold speed value over which the step mode is
automatically switched to Full Step two-phase on. Its value is expressed in step/tick (format
unsigned fixed point 0.18) and to convert it in step/s the following formula can be used:
Equation 8
If FS_SPD value is set to hFF (max) the system always works in microstepping mode
(SPEED must go over the threshold to switch to full step mode). Setting FS_SPD to zero
has not the same effect as setting step mode to full step two phase on: zero FS_SPD value
is equivalent to a speed threshold of about 7.63 step/s
The available range is from 7.63 to 15625 step/s with a resolution of 15.25 step/s.
9.1.10
KVAL_HOLD, KVAL_RUN, KVAL_ACC and KVAL_DEC
The KVAL_HOLD register contains the KVAL value that is assigned to the PWM modulators
when the motor is stopped (compensations excluded).
The KVAL_RUN register contains the KVAL value that is assigned to the PWM modulators
when the motor is running at constant speed (compensations excluded).
The KVAL_ACC register contains the starting KVAL value that can be assigned to the PWM
modulators during acceleration (compensations excluded).
The KVAL_DEC register contains the starting KVAL value that can be assigned to the PWM
modulators during deceleration (compensations excluded).
The available range is from 0 to 0.996 x VS with a resolution of 0.004 x VS as shown in
