Here is the link to that forum thread: Message 8 of 8. How fast does your system react? As I said, I think it’s a formatting issue rather than a coding one, and I’ve not seen the error code I’m recieving before. Why do you use the Autotuning version of PID?

Here is the link to that forum thread: When transitioning from manual to automatic control, the PID controller sets the pressure sico maximum and then slowly brings it back down to the setpoint value. I also tried to lbaview with the PID gains in the VI and found that if I disable the “I” and “D” parameters set both to 0I no longer suffer from the huge bump, but the PID controller cannot bring the process value to the setpoint as there is always an offset.

Here is some background information about the pump I am using: Message 7 of 8. This syringe pump has input and output in pressure and is used to apply a force in order to keep vertical displacement of a sample constant.

Core Analysis App Note. I’m unsure what else you require? When cold starting the VI pimp automatic control mode with true for reinitialize, the PID controller sets the pressure to the minimum and then slowly brings it back up to the setpoint value.

Install the driver according to the installation instructions in the manual provided. Can you do something like this? Not only does it handle exceptional low-flow stability with ease, but it gives you the ability to reach pressures of 2, bar 30, psi.

Message 10 of Message 5 of It looks like the valid range for “I” and “F” are from Without any derivative action, I tried a variety of values for both P labvieew I ranging from 0 to 10 pummp I cannot seem to find one that allows for the system to stabilize.

All D-Series pumps have mechanical and electrical fail-safes, in addition to the factory default or user-set limits.

Reactive Spray Deposition App Note.

Is this an option? Message 3 of 8.

Message 8 of Can you please attach the pdf of the pump. Is there a chance you left out a decimal point on the F value because seems like it could be too large of a number.


Getting Started Make sure that your computer meets the requirements. Does your system react in a linear fashion?

Isco 260D Syringe Pump

The white paper I linked isn’t very helpful in terms of step-by-step instructions. When you purchase instruments from Teledyne ISCO, you not only receive innovative, high quality products, you also receive excellent customer service and product support.

Redundant safety is designed in. Message 9 of The pump is in steady state as shown in the pressure and setpoint chart in manual mode initially and then switched over the automatic control where the huge bump is.

However caused and on any theory of liability, whether in contract, strict liability, or tort including negligence or otherwise arising in any way out of the use of the provided driver or software, even if advised of the possibility of such damage. I used the autotuning advanced PID vi to test out autotuning; however, the Vi would also output maximum pressure and the PID parameters would not change.

As I said, I think it’s a formatting issue rather than a coding one, and I’ve not seen the error code I’m recieving before. To get back to your thread title:
