Thread: Powertran VFD problem
Threaded View
-
Has anyone experience of the Powertran VFD running a 2.2kw water cooled spindle, machine was cutting and suddenly powered down close to running for 1 hour with an error (E.pho) looking in book it states: (Inverter output phase-lost) but cannot find anything about how to trace and rectify.
VFD and motor is about a year old but this is the first time running them, did the test runs for 10 mins between at the different speeds to run the bearings in, then after set a program to run, motor and water never even got warm.
Found the 4 pin plug on the wire to the motor was not held tight so made good, not solved the problem.
Can anyone advise what to try next please.
