Are the voltage measured (cross lines) are before or after the VFD? In any case, the variation is bigger than expected.ģ. Is it a VFD?Ī) The motor is not turning when directly connected to the lines?, orī) The motor is not turning when connected to the output of the VFD?Ģ. I have it wired for the low voltage diagram shown on the motor'.ġ. The voltage stamped on the motor is 230-460. When I measure each line to ground I get line 1 124, line 2 225 and line 3 124. Line 1 to line 3 245V and line 2 to line 3 251.#3. I measure the voltage on line 1 to line 2 260V. I have a 10 hp motor and when I turn it on it just growls and won't turn.
