Greetings Experts,
I have a project where i am supposed to apply load to an element. Now the value at which load is to be applied is known and i am reading it from my load indicator through RS-485 Modbus RTU protocol. The load application starts when i give 0 - 10 VDC to my servo drive. The speed of the load application depends upon the voltage applied to my drive. When 10 VDC the load is applied quickly and at 0 the drive stops which means that load is not being applied.
I want to generate 0 -10 VDC in my plc when i write current load value and set point load value to the plc's memory. Thus plc should generate the voltage value accordingly using PID algorithm. That generated VDC will control my drive speed. If i apply the voltage in -10 - 0 VDC then drive is running in reverse direction which means the load is being released.
Can i full my requirement of controlling the drive using PLC. I can write the current value and set point value in my plc's memory.
Any help would be grateful. I don't know much about hardware.
