Short Axis Pulse Equalization

Usually in interpolation driving, all of axes that perform interpolation do not output drive pulses at regular intervals during driving.

As shown in Fig. 3.6-1 a. below, in 2-axis linear interpolation, the axis (long axis) that has longer moving distance (pulse) outputs

pulses continuously; however, the axis (short axis) that has shorter one sometimes outputs and sometimes does not output pulses

depending on the result of interpolation calculation. In a stepper motor, these uneven pulses may increase mechanical vibration.

Short axis pulse equalization mode is the function to improve this problem. Even in the axis has shorter moving distance, it can

output drive pulses as equal as possible. The following Fig. 3.6-1 b. shows the waveform of the output pulse when short axis pulse

equalization mode is enabled.

Fig. 3.6-1 Pulse Waveform in 2-axis Linear Interpolation (Finish point X:30, Y:26)

Short axis pulse equalization performs the interpolation calculation in the IC, enhancing by several times than usual. Because of

that, the setting range of parameters is restricted by 1/8 as shown in the table below. When enabling short axis pulse equalization

mode, be sure to perform interpolation driving within the range of the following table.
