Yes I was more referring to the reaction speed of control system to stop the motor when it detects the increased torque/current. The digital outputs on the drive are mechanical relays which will have a slower response than a solid state output. If the power was removed from the motor, allowing...
Ok I think I have found a potential solution?
There is a DO I can use that will tell the PLC when the motor increases passed a preset current value (in P3.17) up to the rated current of the motor. I can essentially use to set my maximum torque, if the motor slips and increases current due to...
Thanks all for your input. Just a few notes.
There is little risk to personal safety if the machine jams and the functions of P6.10 and P6.11 prevent movement. The machine is guarded and controlled by a remote pendant away from the machine so the operator would need to stop pressing the button...
Thanks itsmoked.
Yes I am using this but it only allows over torque in either acceleration or constant speed, not both. I have it set to constant speed and checked it worked fine, if they happen to actuate the motor as it snags during acceleration I believe this is when it does the damage.
I...
Hello I have a question about a VFD controlled motor.
I have an AC motor controlling a relatively constant torque load that has a rated torque far above the requirements for the system. Once in a while the mechanical system will jam causing physical damage to the system before any over...
