1, the magnetic sensor type spindle stop stop device

< br / >

magnetic sensor spindle stop - stop device is using magnetic sensor to detect and locate. Magnets are installed on the spindle, magnetic sensor fixed outside away from the magnet rotating track 1? 2 mm, and through the amplifier is connected to the main control unit. When the main control unit must stop when the signal ORT received from the numerical control system, the spindle speed must stop when the set speed. When the main control unit receives signals from the magnetic sensor, the spindle drive immediately into magnetic sensor position closed loop control as the feedback element, target location stop position. Stopped, shaft drive to the NC system sends a stop sign.

installed on the spindle motor or the position of the encoder and the spindle box on the main 1:1 can be used to implement the location of the synchronous rotation encoder must stop? 吗? Control. Must stop Angle can be set freely. Main shaft driving device can automatic conversion in order to make the spindle drive is in a state of speed control and position control.

3, CNC numerical control lathe factory system control spindle stop stop devices

< br / >

must stop Angle can be set to any value by nc system, and must stop by the nc code M19 is carried out. When performing M19 or M19S x, M19 sent to the PLC will first CNC system, signal control, after processing by static control spindle motor, under the original high-speed orientation rapidly rising or rapid deceleration must stop setting in nORT running speed, look for the main shaft encoder zero pulse C, and then enter the position closed-loop control condition, and according to the system parameter setting directions must stop. If there is no execution M19 S instruction, the spindle must be in relation to the default location of the stop C pulse. If to execute commands M19S x, the spindle must be parked in the instruction, the relative zero pulse of xx degree. Spindle orientation to stop the specific control process is slightly different in different systems, but similar.
