9.1.1
ABS_POS
The ABS_POS register contains the current motor absolute position in agreement to the
selected step mode; the stored value unit is equal to the selected step mode (full, half,
quarter, etc.). The available range is from -221 to +221-1 microsteps.
At power-on the register is initialized to "0" (HOME position).
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).
9.1.2
EL_POS
The EL_POS register contains the current electrical position of the motor. The two MSbits
indicate the current step and the other bits indicate the current microstep (expressed in
step/128) within the step:
When EL_POS register is written by the user the new electrical position is instantly
imposed. When EL_POS register is written its value must be masked in order to mach with
the step mode selected in STEP_MODE register in order to avoid a wrong microstep value
generation (see paragraph 9.1.19); otherwise the resulting microstep sequence will be
incorrect.
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).
