Rack and Pinion Linear Actuators. Free Shipping for Online Orders. Terms and conditions apply. The NX Series servo motor drivers allow for easy operation and control of the servo motors. The driver provides automatic tuning allowing for optimal performance without manual adjustments.
As with a stepping motor, stable operation can be achieved in high inertia drive and belt mechanism drive applications without gain adjustment using the servo motors. Also, adjusting the gain manually enables operation under even more stringent load conditions.
With automatic tuning, operation up to 50 times the rotor inertia is possible. With manual tuning, operation up to times the rotor inertia is possible. Belt mechanisms can be operated with the same performance as a stepping motor without the occurrence of vibration before stopping. Basic settings and adjustments are made with switches and potentiometers on the front panel. This design allows for easy control without a computer and even saves the hassle of complicated UP and DOWN key operations.
By using the control module OPX-2A [sold separately] or data setting software MEXE02 [sold separately], it is possible to perform changing of parameters, function setting and monitoring that is better suited to your system.
The built-in, high-resolution bit absolute encoder enables highly accurate positioning of the servo motor. High-speed positioning can be performed utilizing the high-speed and high response characteristics. Eliminates load resonance by adjusting the potentiometer. This adjustment can be made easily and without searching for the resonance frequency. Use as an absolute system by attaching an optional battery sold separately is possible.
Servo drive software provides a means of configuring a motor controller and tuning the servo loops in addition to programming built-in functions. Each component of the software is designed with a focus on the end-user requirements, with user-centric features that offer you improved performance and refined experience— all of which make a huge difference.
Step motors also known as Stepper motors and stepping motors rely on even current pulses to turn a motor in defined steps. Servo motors, on the other hand, run on a continuous current to reach a specified torque, velocity, or position. The current delivered to the motor is determined by a controller, which gets information torque, velocity, or position from an encoder.
The controller sends the latest commands to the servo driver amplifier , providing your motor with the precise current required to address any differences between command values and the actual values.
The servo commands are the required gain parameters which are set by a user, depending on various machine loads and operating conditions.
The more optimally set these parameters are, the more accurately a servo motor can track the desired position in various motion profiles. Velocity feed-forward works during the constant velocity portion of the move profile. It minimizes following error and improves response time by multiplying the derivative of the position command i. Acceleration feed-forward works during the acceleration and deceleration portions of the move and can eliminate overshoot caused by velocity feed-forward.
Acceleration feed-forward multiplies the second derivative of the position command i. You must be logged in to post a comment. Then you can raise the voltage to the required level per your servo drives. This will help keep the axis you are tuning from jumping around on you. The videos listed below should help to ease the confusion for the novice. This first video gives a pretty clear graphical explanation of how to proceed. Graphical Description Video As shown in this first video the Ap adjustment is done first.
Then finally the Ai is dialed in. Be patient as while it goes quickly in the video it will still probably take a first-timer a number of trial and error attempts to get similar results to the video description. While this video is in reference to quadcopter drone servos the process is the same for your CNC servo drives. The second video gives a visual explanation of PID tuning.
