Indeed, you can modulate the motor current limit using the parameter 0:422[Current Limit 1]. However, be aware that as soon as the current reaches this current limit, there will be a compromise on your commanded speed up to the immobilization of the motor. You can observe bit 0 [Current Limit] of parameter ...

Bonjour Russel, Noise can affect the volatile memory. Here is how and why. Each time you make an edit, the firmware is calculating a new memory checksum value and stores it as a reference value in a register. That is the same for a SLC, a PLC-5 and a ControlLogix. Before each program scan, ...

Do the pull test with your hands. If one of the connectors pulls off, re-crimp all connectors; adjust the crimp force screw (crimp pliers) to the maximum. ##HL31

Did you use the 1786-CTK ControlNet Coax Tool Kit ? Do a "Pull Test" on each end BNC connectors (black coax trunk line). They must retain a 60 pounds weight, but, if BNC connectora are not correctly installed, ti will be easy to pull off. If possible, replace very short coax lenghts with bullet ...

I had that problem a long time ago. Need more info. Is that appening only at one location (node)? Is it a redundant media network? 1- If you have any serie A RPA, they need to be rev G01 or higher. If not, you can have intermittant blinking red led (and disrupted I/O) 2- Make sure to declare ...

The ground fault is detected by an internal CT around the three output phases. At any point in time, the total current read by that CT must be 0. If not, there is one phase leaking to ground. The trip level is not adjustable. 1- The fault is real: check the output phases unbalance. Check for resistive ...

You need to use the "Min Torq/Spd" mode [Parameter 88, Speed/Torque Mode = Min Torq/Spd] and set the command speed to the maximum speed you don't want to exceed. It must be set higher than the actual speed while pulling the wire. If you have a wire break, the speed loop will take over and regulate ...
