9.1.6
DEC
The DEC register contains the speed profile deceleration expressed in step/tick2 (format
unsigned fixed point 0.40).
In order to convert DEC value in step/s2 the following formula can be used:
Equation 5
DEC is the integer number stored into the register and tick is 250 ns.
The available range is from 14.55to 59590 step/s2 with a resolution of 14.55 step/s2.
If the user tries to set DEC parameter to zero, command is not performed and
NOTPERF_CMD flag is raised (see paragraph 9.1.22).
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).
9.1.7
MAX_SPEED
The MAX_SPEED register contains the speed profile maximum speed expressed in
step/tick (format unsigned fixed point 0.18).
In order to convert it in step/s the following formula can be used:
Equation 6
MAX_SPEED is the integer number stored into the register and tick is 250 ns.
The available range is from 15.25 to 15610 step/s with a resolution of 15.25 step/s.
If the user tries to set MAX_SPEED parameter to zero, command is not performed and
NOTPERF_CMD flag is raised (see paragraph 9.1.22).
9.1.8
MIN_SPEED
The MIN_SPEED register contains the speed profile minimum speed expressed in step/tick
(format unsigned fixed point 0.24).
In order to convert it in step/s the following formula can be used:
Equation 7
MIN_SPEED is the integer number stored into the register and tick is 250 ns.
The available range is from 0 to 976.3 step/s with a resolution of 0.238 step/s.
