◆ Support multiple frequency settings: digital setting, analog setting, PID setting, RS485 communication setting

◆ I/O terminals can be freely programmed to combine multiple working modes according to user needs.

◆ With jump frequency control function, it can effectively suppress mechanical resonance and make the system more stable and reliable.

◆ With instantaneous power-down retention function, it can avoid the impact of production due to instantaneous power failure

◆ With over torque and under torque detection

◆ Automatic voltage adjustment function to effectively solve the low frequency oscillation problem of high power motor

◆ Provide a variety of fault protection functions: over-current, over-voltage, under-voltage, over-heat, overload, lack of equal real-time monitoring and protection to ensure safe operation



winding machine,mixer, extruder,slitter,winder,compressor,ventilator,pump,grinder,conveyor,elevator,centrifuger and other speed control machines.



DO NOT set up the inverter by yourself if you don't know how to, or it will make both the spindle and inverter burn easily.

Please contact us, we have manuals, videos and pictures to help you.




  • Spindle working environment temperature is usually -10  ~ 40 .
  • Before installing the first electric spindle axis head turned by hand, should feel flexible, non-blocking phenomenon.



  • Spindle in the preservation and transportation, high-speed grease inside the bearing state will change, customers should be running at low speed for 30 minutes. 3000 rpm and then follow the poor increase, run 20 minutes each. Spindle and the inverter should be working together. The inverter's specifications and parameter settings need match spindles parameter.

  • Connect the inverter spindle, three-phase inverter power cord should be soldered in the plug 1 (U), 2 (V), 3 (W) feet, 4 feet for the ground. After the power is turned on, to observe whether the spindle rotation axis indicates the direction consistent. If inconsistency should be immediately shut down, replace the inverter and spindle connected two wires of three-phase power supply.

  • It should ensure that before use of water-cooled spindle, the cooling system is working properly. Every day before using the spindle must be running at low speed for 15-20 minutes. Clamping the cutters to spindle, collet nuts ,collets,cutters must be clean enough. Shank inserted into the collet must be greater than 15mm.




  • Water cooled spindle MUST be used with water pump. Otherwise the spindle will soon broken.

  • AC spindle motor MUST use with inverter. The power of inverter need equal or bigger than the spindle power. Before using,please set up the inverter parameters suitable for spindle. Otherwise the spindle and inverter will broken at once.

  • When you use the spindle,the noise is not same as always,please STOP the spindle at once. You may need to replace the spindle bearings.



1. Cooling in different ways: water-cooled spindle motor is the use of the water cycle to cool the heat generated after the high-speed rotating spindle, spindle motor with fan-cooled approach to cooling.

  • 2. Noise: Water-cooled spindle motor is basically no noise, but the air-cooled spindle motor is very loud.

  • 3. Life aspects: Water-cooled spindle motor pay attention to maintenance, frequently changes the water or the use of industrial water coolers, air-cooled spindle fan mainly by the wind blowing the heat transferred to the heat sink, so as to achieve the cooling effect.

  • 4.If you need use for metal ,hard wood,granite,stone,you can choose metal spindle.Metal spindle much better than wood spindle.
