Synchronizing controller64 MG.10.N4.02 - VLT is a registered Danfoss trademarkParameter 721 Slave marker type: As external marker signals are used, you can set the typeof edge triggering of the external marker signal; “2” for a positive edge, “3” fora negative edge.Parameter 722 Slave marker interval: Record the interval between two marker signals of theslave. Input of the interval is in quad counts. If the interval is not known, it canalso be determined during the test run.Parameter 723 Master marker type: As external marker signals are used, you can set the typeof edge triggering of the external marker signal here; “2” for a positive edge,“3” for a negative edge.Parameter 724 Master marker interval: Record the interval between two marker signals of themaster. Input of the interval is in quad counts. If the interval is not known, itcan also be determined during the test run.Parameter 725 Test run speed: Record the speed at which you want to carry out theoptimization run. Record the speed as a percentage of the speed in Parameter716.Parameter 726 Test run acceleration: Record the acceleration for the test run in percent of theminimum acceleration time. 100% represents the minimum acceleration, 50%is half as fast as minimum acceleration; the ramp time is thus twice as long.Parameter 727 Test run distance: Record the distance (quad counts) for the drive to travelduring optimization.How to check the motor connectionWhen you have programmed the above parameters you check the motor connection as follows:1. Remove all signals to terminals 16-33 and I1-I8). Only input 27 must be connected andclosed.2. Select “Local” function in parameter 002. – VLT 5000 stops (display flashing)3. Set the frequency for a low value, for example 3 Hz in parameter 003.4. Press the [START] button on the VLT 5000 control panel and then the [STOP/Reset]button watching the direction of the motor. If the motor rotates in the wrong directionthen exchange the motor phases.How to test the incremental encodersWhen you have tested the motor speed direction you test the incremental encoder connectionas follows:1. Remove all signals to terminals 16-33 and I1-I8. Only input 27 must be connected andclosed2. Press the [DISPLAY/STATUS] button on the VLT 5000 control panel. Now the followingvalues appear in the upper line of the display: slave position, master position and trackerror.3. Rotate the slave drive motor shaft manually in the allowed direction. Now the displayshows an ascending count of the slave position. If the count is descending, exchangethe slave encoder track A by B and A/ by B/. If there is no counting in the display thencheck the wiring of the encoder.Follow the same procedure when you test the master encoder. Note: To be right the count mustbe ascending here.
