Hi everybody!
i am using Maxon ADS 50/5 in current control mode. i have turned Potentiometer P4 to a little higher than the minimum position for the Imax but how do i know abt current value of Imax?? Also Current monitor is not working, i enable the drive and motor starts drawing the current but...
Hi all,
i need to provide a reactional torque to my hand by using a dc servo motor in current control mode. however i am just wondering what would happen to dc motor at stall torque?? i mean if i put my hand on the shaft and resist the generated torque by motor. At the same time if i control...
i was considering my measurement system's ground to be isolated from my simulated RTD (DPMs) system. Then just as an experiment, i made both systems ground common, noise got removed nd i was happy at the end of the day but i was shocked by this coz DPM ws only acting as a variable resistor nd i...
i think em quite clear now. Anyways as i have earlier mentioned abt measurement sys. it is a data acquisition system for multi channel RTDs. 1mA excitation for POT is also being generated by this system. The voltage generated as a result of this excitation is low pass filtered, then amplified...
barry thnx for ur response but i think u didn't get it. this 165 degrees is different from IC operating temp range u just mentioned above. 165 temp means pot is offfering approx 140 ohms resistance. 25 degree variation means pot's resistance value is varying by 6 ohms. nd u know abt RTD's then...
yes i am exciting DPM by 1mA current through mux actually, 1mA current continuously for 40ms, then mux switches to another channel hence a pause of smaller duration and again 1mA current for another 40ms nd so on. i am observing temperature on the PC based HMI as well as the voltage of ADC on...
Yes, current is constant 1 mA but it comes through mux , for 40msec it remains constt 1mA, then it switches from one channel of mux to other and again remains constt for 40msec. i am measuring voltage via PC based HMI of a Data acquisition system. when i use simple pots , i get no fluctuations...
Hi,
em using DPM AD8403 for simulationg RTD's. without excitation, meter shows a contant resistance value but when i excite the DPM by 1mA current then there are big fluctations in my voltage readings quite often. can any1 help me on this?? please its urgent...:sad:
