High-speed and high-precision interpolation
The motion controller of Techno has interpolation accuracy of 1 pulse even at high speeds.
The techno motion controller allows for high-precision trajectory and speed control in interpolation and synchronous operations. The accuracy is about 1 pulse. If we assume the pulse unit is nm, the command error would be 1 nm. While there are error factors in the actual operation, including the entire servo system comprising the servo amplifier, motor, encoder, and mechanism, the motion controller on the command side can control very accurately and smoothly. The accuracy analysis function (TPC logging) can also be used for easy evaluation and verification. Here, we will introduce examples of "accuracy verification of linear interpolation trajectory and speed" and "torque measurement." For more details, please contact us.
basic information
【Case Study】 ○ Verification case of linear interpolation → We verified the accuracy of linear interpolation (trajectory accuracy and speed accuracy). High precision has been achieved with errors below μm. → Case of PLMC-M3EX and Σv servo Example settings: Movement distance: 100000p (1p = 0.01μm, equivalent to 1mm) Speed: 500kpps (1mm in 0.2 seconds) Results: Acceleration/deceleration time: 10 msec No speed ripple: so small it is undetectable. ○ Verification of the linkage between linear interpolation and torque command → Verification of position, speed, and torque is possible. In injection molding and bending processes, it is necessary to approach at an appropriate speed and smoothly apply the specified torque. Linear interpolation commands and torque command instructions were described in Techno language. → Points: Easily described in Techno language. Smooth transition from standard speed specified linear interpolation to torque control. Accurate pressing operation in the shortest time. ● For more details, please contact us.
