Yaskawa Servopack 0-230V 3 Phase 40.0A 7.0KW Industrial Servo Drives SGDB-60VDY189

As an example of this tuning approach, we investigate the response of a Parker BE342A motor with a generic servo drive and controller. This servomotor has the following parameters:
Motor Total Inertia J = 50E-6 kgm2
Motor Damping b = .1E-3 Nm/(radc)
Torque Constant Kt = .6 Nm/A
We begin with observing the response to a step input command with no disturbance torque (Td =0).
Step 1:Fig. 2a shows the result of slowly increasing only the proportional term.
The system begins to oscillate at approximately .5 Hz (fo =.5Hz) with Ko of approximately 5E-5 Nm/rad.
Step 2:Using these values, the optimum P.I.D. gains according to Ziegler-Nichols
(Z-N) are then (using equation (6)):
Kp = 3.0E-4 Nm/rad
Ki = 3.0E-4 Nm/(radgsec)
Kd = 7.4E-5 Nm/(radc)
Fig. 2b shows the result of using the Ziegler Nichols gains. The response is somewhat better than just a straight proportional gain. As a comparison, other gains were obtained by trial and error. One set of additional gains is listed in Fig. 2b. Although the trial and error gains gave a faster, less oscillatory response, there is no way of telling if a better solution exits without further exhaustive testing.

 

 

 

 

 

 

 

With the PATH Plus configuration program, you can quickly and easily configure frequency-converter-supplied drives in threephase technology for the SIMOVERT MASTERDRIVES Vector
Control and Motion Control device family.
PATH Plus is a powerful engineering tool that will assist you throughout all of the configuration steps, from configuring the incoming unit to the motor.
The system components and required motor are determined for a drives task through menu-based selection and layout of the frequency converters. Automatic display of configuration notes ensure error-free planning.
In addition, an extensive help system assists first-time users in operating the program. Using the mechanical requirements of the driven machine as a basis, PATH Plus guides the configuring
engineer through a logical, user-friendly dialog procedure to a safe, reproducible, economical drives configuration. The technical data of the established frequency converters and motors, the selected system components, and the required accessories are listed in detail.
With PATH Plus, drives can be configured based on a load characteristic
or load cycle, enabling configuration of applications
such as:
■ Running and hoisting gear
■ Slewing gear
■ Spindle drives
■ Center winders
