  1. Hola amigos, tengo un oplc visión V350-35-T2 y un variador de frecuencia delta MS-300. Quiero realizar la siguiente operación: Mediante Modbus RTU manipular el parámetro 01-00(frecuencia máxima) del ms-300, el asunto es que enviaré valores con decimales, que se obtendrá a través de cálculos matemáticos dentro del oplc. ¿Alguien sabe cómo poder enviar valores decimales por Modbus?
  2. Before I only used 1 single input, since I added the two inputs, the problem started. (1 week ago)
  3. Hello, I had an error with this module. Suddenly it stopped generating the analog outputs, and the RUN led blinked. It is worth mentioning that I am using 3 inputs and 2 outputs (all 0-10v), one of the inputs is 0-8v with 16-bit resolution. Is the problem related to this?
  4. En efecto busco que ese valor de captura sea el mismo,que no tenga variacion [La cual la tuve con un encoder incremental utilizando el reservado numérico para generar 0-360 grados
  5. En efecto,estoy buscando un encoder absoluto de preferencia de salida binaria. Lo que busco es capturar el valor del encoder [0-360] en el instante que una bandera en el eje pasa por un sensor inductivo Este se repite en cada vuelta del eje, es para un proyecto de sincronizacion entre dos ejes El valor capturado será usado como posición de sincronizacion" Master"
  6. Hola ,deseo leer los12 bits( paralelo) de un encoder absoluto ,¿es posible hacerlo mediante modulo de entradas digitales ? O debería agregar un módulo de entradas de alta velocidad? teniendo en cuenta que el eje gira a 1,2 hz(aproximadamente 1 giro por segundo)
  7. HELLO, I have an oplc vision V350-35-T2, I want to make a modbus communication with two frequency inverters through the communication connector configured in RS-485. I want to know if in this configuration it is possible to load/download the oplc and enter online mode.
  8. I have managed to download the software, but apparently it tells me that in order to use the printer mode, I should have the printing roller as master and the transmission chain as slave. Here I would have a problem since the transmission chain is commanded by a variator of frequency
  9. Hello kratmel, I am using a DELTA ASDA A2 servo motor for the print roller. Originally both axes were linked by mechanical gears, but later the axes became independent, removing the gears in order to quickly power the printing roller (for rectification/repair services), This led to the task of performing an electronic synchronization
  10. La tolerancia de grados deber ser máximo +/- 1 grado La sincronizacion inicial puede tomar un tiempo digamos de 10 segundos,aproximadamente 9 vueltas del esclavo. El eje maestro es comandado por un variadr de frecuencia a velocidad fija y el esclavo por un servomotor ,el cual utiliza una entrada analógica de 0-10 voltios como comando de velocidad
  11. Hi Joe, the master axis rotates at 64.8 rpm (fixed speed) equivalent to 2700 pulses / second, read as encoder frequency (2500 PPR). The second axis has the same encoder (2500 ppr) . I made a PID routine so that the slave axis is equal to the master frequency, the only thing missing is the correction so that the two axes are synchronized. (and your inductive sensors can match), the timing accuracy should be at least acceptable. The system is a coated machine, which consists of a varnishing roller (slave axis) which prints varnish on aluminum sheets, these aluminum sheets are entered into the printing area through a transmission chain (master axis). The objective is that the impression coincides with the beginning of the aluminum sheets with a tolerance of 1 millimeter. I enclose a reference image
  12. HELLO COMMUNITY, I need to perform a Master / slave synchronization task of two axes (two motors )(VISION V350 -T2 : The speed of the master is fixed and the slave must rotate at the same angular speed as the master, after that, the slave must make a correction to synchronize with the master. Each axis has an encoder and a synchronization sensor. So far I have managed to control the speed, taking the frequency reference of the Master encoder, (The master speed is fixed). I have also created a subroutine which converts a turn of encoder in a reading from 0 to 360 degrees (I have done it for both axes), I only need to do a position control; so that the slave motor performs a speed correction (increase or decrease) until the synchronization position is reached Does anyone have a way to achieve and maintain that final position correction?
  13. PUT THE TIMEOUT IN 30, seconds, and the problem is corrected, thank you men
  14. PLC COM 1 IS SET TO "SERIAL", I AM USING AN "ATEN" CONVERTER; AFTER THAT THE BOOTSTRAP SCREEN NEVER APPEARS,
  15. WHILE I WAS TRYING TO UPDATE THE OPERATING SYSTEM, THE SCREEN TURNED RED, THEN I FOLLOWED THE PROCEDURE OF TOUCHING THE LCD SCREEN BEFORE POWERING UP THE UNIT; AFTER THAT THE SCREEN REMAINED BLACK AND BEEPING
  16. Hello, I have the same problem, my LCD is black and the beeps are heard consecutively; following your steps, at no time do I see a "bootstrap" screen, only everything remains black and the beep stops sounding
