Creating a Servo Motor Home Operation Function Block with Axis Indexing ?
seroke posted a topic in Mitsubishi
Hello everyone, I'm writing a block in GX Works3 to perform the "Home" operation of a servo motor. (The algorithm inside the block has been tested and is working.) However, in projects with many servo motors, I want to use the block. The axis number will be requested from input the block, and the value received needs to be indexed into the places labeled as "Axis" within the block. And I need values like (4*(AxisNo))+2 inside some structure labels. The function block I want to create will look like the attached file. Which methods should I use to achieve this, and how can I do it? I tried using arrays but couldn't succeed. Example; If I enter a value of 2 for the Axis, the labels below will look like this: FX5SSC_1.stnAxCtrl2_D[Axis].uPositioningStart_D.0 ====> FX5SSC_1.stnAxCtrl2_D[2].uPositioningStart_D.0 FX5SSC_1.stSysCtrl_D.uExternalInputOperationDevice1_D.(4*Axis+2) ====> FX5SSC_1.stSysCtrl_D.uExternalInputOperationDevice1_D.10 -
Hi! I would like to do some tuning on our machine, but the problem is that the machine stops and drops origin positions. I selected User Command method with Basic setting. After 5sec I started the tuning, the machine stops with the roblem of that axis. Is there a parameter bit that goes high (or low) during tuning? There're no strange sounds nor movements..even the amplifier doesn't give error code. Is there something else that i should check? In the Servo-Adjustments parameters, One Touch Tuning setting I found the Permissible Overshoot Amount Level is set to 0. Can it be the problem?

Hi. I am planning to do a full scale servo tuning on our producting machine. Is it possible to do it while the servos are in, assambled? I mean no production, no disassembling, servos stay where they are, just tuning them one by one with their empty load..

Hi all! We have a problem with a Mitsubishi system. After switch off the machine in home position and back on, it resets the servo encoder value to 0. I checked the servo parameters, and the Absolute encoder is enabled, the ext. battery is ok and no zero reseting in the program ( I think...). Is there a parameter I should check or some setting in the intelligent module? The system consists Q01CPU, QD77MS2 im., J4 200B amp with 6v battery, and HG-SR152 motor.

Hello everyone! I have problem with understanding the usage/principle of operation of parameter "Mark detection number". In manual i read: "The number of mark detections is stored. "0" clear is executed at power supply ON. Continuous detection mode: 0 to 65535 (Ring counter) Specified number of detection mode: 0 to 32 Ring buffer mode: 0 to (number of buffers - 1) Refresh cycle: At mark detection" My question is which mark detections are stored? Servo detects some kind of marks? I am novice in servo programming, please explain in the easiest way. Thanks for help.
