ALWAYS use shielded 3 conductor cable on ALL VFD wiring.
ALWAYS ground the shield on both ends.
You can use shielded cable for your modbus coms if you want to. it will not hurt. but the real issue is VFD cabling.
on most VFD the voltage is a user input. You tell the drive your incoming voltage. It then operates to control current to spin the motor. VFDs operate by switching current on or off. this produces an average current through the drive that results in motion, etc.
are you sure that this drive...
First topic
Consider a motor-generator set. If you can find a single phase driver at that capacity (doubtful) then it can drive a three phase generator.
Second topic:
ANYTIME you use a VFD you should use shielded cable. ground the shield on both ends. (Ground loops are a worry only in...
Current from the AC line is exactly the same as the current into the DC motor. DC drives are FET or SCR based and either conduct current or do not conduct current.
DC drives are current controllers. All they do is control current into the motor.
If you protect the AC line against short...
I have no direct experience with ABB Flash Disk, but in our experience with every other Flash Disk based storage, the generic devices work as well as the vendor labeled device.
Not all Flash Disks are equal. some will not work in cameras, etc, and others will. at the cost of the vendor...
