9.1.3
MARK
The MARK register contains an absolute position called MARK in agreement to the selected
step mode; the stored value unit is equal to the selected step mode (full, half, quarter, etc.).
It is configurable by user through a SetParam or GoUntil command (see paragraphs 9.2.2
and 9.2.9).
9.1.4
SPEED
The SPEED register contains the current motor speed, expressed in step/tick (format
unsigned fixed point 0.28).
In order to convert the SPEED value in step/s the following formula can be used:
Equation 3
Speed is the integer number stored into the register and tick is 250 ns.
The available range is from 0 to 15625 step/s with a resolution of 0.015 step/s.
Note:
The range effectively available to the user is limited by the MAX_SPEED parameter.
Any attempt to write to the register causes the command to be ignored and the
NOTPERF_CMD to rise (see paragraph 9.1.22).
9.1.5
ACC
The ACC register contains the speed profile acceleration expressed in step/tick2 (format
unsigned fixed point 0.40).
In order to convert ACC value in step/s2 the following formula can be used:
Equation 4
ACC is the integer number stored into the register and tick is 250 ns.
The available range is from 14.55 to 59590 step/s2 with a resolution of 14.55 step/s2.
If the user tries to set ACC 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).
ACC value hFF is reserved.
