meanwhile, the parameters of pulse string AB is still set by P21 group. In speed mode, the filter
time of pulse string AB is determined by P21.29.
Step 8: The input frequency of pulse string is the same with the feedback frequency of encoder
pulse, the relation between them can be changed by altering P21.11 (numerator of position
command ratio) and P21.12 (denominator of position command ratio)
Step 9: When running command or servo enabling is valid (by setting P21.00 or terminal
function 63), it will enter pulse string servo running mode.
4. Commissioning procedures for spindle positioning
Spindle orientation is to realize orientation functions like zeroing and division based on
closed-loop vector control

Step 1–4: These four steps are the same with the first four steps of the commissioning
procedures for closed-loop vector control, which aim to fulfill the control requirements of
closed-loop vector control, thus realizing spindle positioning function in either position
control or speed control mode.
Step 5: Set P22.00.bit0=1 to enable spindle positioning, set P22.00.bit1 to select spindle zero
input. If the system adopts encoder for speed measurement, set P22.00.bit1 to 0 to select Z
pulse input; if the system adopts photoelectric switch for speed measurement, set P22.00.bit1
to 1 to select photoelectric switch as zero input; set P22.00.bit2 to select zero search mode, set
P22.00.bit3 to enable or disable zero calibration, and select zero calibration mode by setting
P22.00.bit7.
Step 6: Spindle zeroing operation
a) Select the positioning direction by setting P22.00.bit4.
