I have the telemecanique altivar 11 VFD drving my SB Heavy 10. I downloaded the operators manual but dont see the answer to my problem. I am driving a 3PH 220 motor and have 220 single phase input to the vfd. the drive has three programmed set points that I believe one should be able to select to drive the motor those preselected speeds, SP1, SP2, SP3. But my motor only responds to the LSP, lower set point value. If I select the HSP, it still only drives whatever speed the LSP is set to. If I select SP1 same thing.
If I want to drive other speeds I have to put them into the LSP. Does anyone know my problem? I suspect my problem is I am 65 years old and need a 20 year old to program it for me!! Thanks.
