6) Set inverter parameters to make the inverter work under 0~10V analog voltage control mode.
Spindle ON/OFF adopts forward rotation terminal control mode. Press down the [Spindle Start]
button in the software, and observe in the I/O window whether the color of signal dot in front of
“Spindle” turns green, on the terminal board whether the green output indicator LED beside the
corresponding relay becomes brightening, and whether the spindle starts to rotate. If the spindle
does not rotate, please examine the connection of the inverter. Adjust the spindle speed in the
software and the actual spindle speed should be changed correspondingly; otherwise, examine
the connection and the parameters setting of the inverter. If the spindle rotates in a wrong
direction, change the connection between the spindle and inverter: usually, there are three wires
connected with the spindle. Exchanging any two of them will alter the spindle rotation direction.
7) Set subdivision value of stepping motor driver; generally, the larger the subdivision value is, the
higher the resolution will be. But if the subdivision value is too large, it will affect the maximum
feed rate. Generally speaking, regarding the pulse equivalent of a mold machine, 0.001mm/p (the
corresponding maximum feed rate is 9600mm/min) or 0.0005mm/p (the corresponding maximum
