We have bought "KX-3" model milling machine made by SUMORE, china, which is controlled by MACH-3. Machine spindle motor is controlled by a drive "MBLC-1100-300H" made by HONCAR. Spindle motor runs only in general mode, i.e, ON and OFF. "PULSE WIDTH MODULATION (PWM)" mode which is supposed to control the spindle direction and speed is not functioning. In PWM mode the spindle is not at all running. Kindly provide me some solutions over this problem i face. What are all the parameters to be set before working in PWM mode?
