DVC6010 locator adjustment
Thread Content
I have a Fisher DVC6010 locator that is used in conjunction with a current amplifier. The requirements are quite high: when adjusting the parameters of the locator, it works well during upward movement but not during downward movement, and vice versa. Additionally, it needs to respond quickly to small step changes of 3%, which makes tuning it very difficult. Do you have any experience with this?
Be careful not to set the angular travel as linear travel.
It’s the gain parameter; do you have any experience with it?
This is not something that can be clearly explained. Adjust it slowly.
Adjust it slowly; you can just try it yourself
It is indeed possible to bring it out, for example by using three traffic amplifiers or two amplifiers; however, in other cases it’s not easy to do so. The manufacturer needs four to five hours using the Valvelink software, and people are looking for practical course materials or relevant information
Fisher positioners are generally used in situations where high precision in positioning is required. If the problem persists even after automatic calibration, it is recommended to replace the positioner. Such positioners place high demands on the actuator motor and the control motherboard; often, reassembling them does not restore the previous level of control performance.
It is recommended to try modifying the gain of the locator.
It is recommended to first check the output pipeline of the positioner and whether there are any leaks in the cylinder. Then, perform performance optimization adjustments on the positioner to fine-tune the parameters; after the optimization is complete, assess the situation. The sensitivity of the flow amplifier can also be adjusted
The combined accuracy of the locator and amplifier is still quite difficult to adjust
