Industrial Lathe Speed Adjustable Frequency Drive
BEST High-performance Adjustable Frequency Drive can smartly control motor running for industrial automation. It can perfectly control the lathe motion position and speed while being used for various machine tool. Mainly includes series below:
Applied Lathe Types:
Ordinary Lathe: include ordinary lathes, drilling machines, boring machines, milling machines, planing and slotting machines;
Precision Lathe: include grinding machines, gear processing machines, thread processing machines and other various precision machine tools;
High-precision Lathe: include coordinate boring machines, gear grinding machines, thread grinding machines, high-precision gear hobbing machines, high-precision engraving machines and other high-precision machine tools;
CNC Lathe: CNC lathe are short for Computer Numerical Control lathe.
Product Advantages
• While matched with spindle closed-loop vector control encoder, the FC500 series frequency drive can precisely control the motor speed/motion for CNC lathe perfectly.
• The weak magnetic control technology extends the constant power speed regulation range to 3 to 5 times the rated speed.
• Quick braking function (optional braking unit), meeting the requirements for frequent starting and stopping.
• Supports advanced functions such as spindle orientation and rigid tapping
• Equipped with a high-speed spindle application macro, where only one parameter needs to be modified to automatically adapt the high-speed spindle parameters. This provides users with a more convenient experience.
Working Principle:
The CNC center transmits control signals to the servo driver through pulses or buses. The servo driver then performs corresponding electronic gear ratio and stiffness adjustments and transmits them to the servo motor. The encoder feeds back the rotational position of the servo motor to the servo driver. The servo driver compares the output signal with the feedback signal, compensates for the error, and simultaneously transmits the feedback signal to the CNC center.
The operation command of the frequency converter is issued by the numerical control center as an operation instruction. A forward rotation command (input X1). The frequency signal is output by the numerical control system as a speed signal (0-10V DC), and the frequency command can be input from the AVI terminal of the frequency converter to change the frequency of the frequency converter, thereby changing the speed of the motor. The fault signal of the frequency converter (Y1A, Y1B) is sent to the numerical control system. When the frequency converter reports a fault code, the machine tool control system will stop working.
