KX driver SD550 series AC servo screw driving motor


●All fastening conditions can be adjusted to perform the perfect fastening.
 The fastening conditions that Torque, Speed, Angle and Rotation direction can be input directly with numerical value. In response to the screw and workpiece, the fastening condition will be changed for each fastening point, which can be able to install the programs up to 16 numbers. It also performs high accuracy fastening with two-stage fastening process. 

●Add in High speed model
 It creates the high speed models which are use the new 150W motor and reducer

●Innovate a new AC servo motor
 It will be used the most suitable motor for screw driving and make it possible to the high accuracy control. Take care of the trouble by introducing high resolution Encoder with a function to detect error quickly. Reinforced cable connections prevent cable damage.

●Reduce Tool and Controller size and weight 
 Tool size is reduced with redesigned the reducer, which the length is 33mm shorter and the weight is 870g smaller. Controller size reduced to 43% below volume ratio (750g) which will be easy to install to the enclosure.

●Equipped with USB and RS485 Ports 
 It equipped with USB port to communicate with PC. Standard USB cable as commercial item can be used. It is easy to use communication software and improves the performance of maintenance. Additional RS485 port to use communicate with the external device will be created simple network. 

●Available for waveform judgment (Option)
 The current value flow to the motor must be different between normal and fault screw driving. If it makes clear the waveform between, it can be detected screw driving fault. Also when it comes to fault, screw driving will be stopped and helped the damage for workpiece.

※1. 「*」mark into the model number indicates the shape of output shaft as follows.
  M: M8 Thread, H: Hex (6.35mm), S: Square (9.5mm except KX400 / 12.7mm for KX400)
  The Square Shaft is not available for KX050T2-01 and KX100T2-01.
  The Thread and Hex Shaft does not available for KX400T2.
※2. In case of the following conditions will be needed the tightening test with actual Driver.
  If it is necessary, please feel free to ask.
  It is required short cycle time.
  It is need to keep the high torque value during tightening to the tapping screw.
※3. Recommended torque means the torque range that screw fastening can be performed with the best performance.
  Even if it is out of recommended torque, screw fastening itself will be done if torque setting is in the torque setting range.
※4. Rotating speed setting is limited by fastening condition.
※5. 「*」mark into the model number indicates the optional processing function which analyze the wave form is included or not.
  (0: Not include, 2: Include)
