I have a TECO JNEV-101-H1 series VFD, 115v input, 230 3PH output, 1HP
Manual: https://www.tecowestinghouse.com/Manuals/ev_operating_manual.pdf
I have it hooked up to a 1725 RPM Leeson, 1.5 HP motor.
The VFD has a Torque Boost setting, (F48), with a value range from 001 to 450. If i set this value above 250 the motor stops recognizing the input controls fwd/rev and variable speed. The motor stays at a very low rpm and shudders and jumps around, sometimes it will even change direction. The motor demonstrates this behavior no matter what the minimum frequency value is set to in the VFD.
If I set the Torque Boost value down to say 200, the motor acts completely normal and will recognize all control inputs (variable speed, fwd, rev) all the way down to 2 Hz...
Why is the torque boost making the motor act this way? And how can I fix this?
