Existing reviews of 30 hp (22 kW) VFD, 3 Phase 208V, 440V, 460V
A series of question about VFD
can the VFD start normally after removing the motor?
After the VFD displays the E09 fault, please click the shift key on the panel >> to switch to b-12. What is the current value displayed by b-12 in A?
The VFD does not display E09 fault
The VFD starts, the motor turns and tightens up the chains and then stops, will NOT drive the chains with a load on them
The drive does not fault, it just sits there trying
You can tell the motor is trying to move, it maintains tension on the chain but will not move it
If you stop the VFD, the chain gets loose again
That is all the info available

Based on your description, we think the 30HP VFD should be overloaded, because after removing the motor, it can run normally without load.
Therefore, the chain connected to the motor should be a heavy load.
In order to verify this problem, you can ask your customer to remove the chain on the motor, remove the tension, and then VFD and motor again to check whether the 30HP motor can run without load?
If the motor can run without load, it means that the load of the chain is very large and the VFD is overloaded.
What is the best way to set up the parameters for the motor I have installed in the system?
I am not using the displayed numbers. I have attached a True RMS and an RMS clip-on ampere meter to both the input and out terminals. The difference between the True RMS and RMS meters on the input terminal is about 1.5, which makes sense since you are assuming a 1.5 delta between the numbers. One thing both meters agree on is the output of the VFD. They both agree the ampere's read there are just about 30 AMPs. This does not change much if there is a load or not, which surprised me. What surprises me is when there are no restrictions to the flow of water through the pump, the amperes are really high on the input side. Yet when I constrict the flow, the input amps drop like a rock. I would have thought the amps would be greater with a restriction since the pump needs to work harder to push the water. But I'm wrong. What is the best way to set up the parameters for the motor I have installed in the system? Should I peck in the configuration information, or does the Senseless Vector control perform the best?

Please do not worry, we think your VFD is working fine. In fact, the current output by the VFD is related to the operating load capacity of the pump: when you do not limit the flow, the pump needs to run at full speed, and the load is larger, and the relative current is larger. Conversely, when the pump is limiting flow, the pump does not need to run at full speed to reach the target water flow, and the current is relatively low, which is normal. Now you just need to change the circuit breaker on the input side of the VFD to a larger capacity 80A. VFD does not need to set motor parameters.
3 phase vfd can be run CNC spindle motors?
My supply voltage is 3 phase, 480V, can I use your 3 phase drive, and adjust its output to 380V, 400Hz to run my CNC spindle motor?
