I have a TECO FM50 VFD (FM50-201-OC) installed to operate the motor of my South Bend 10L Lathe.
The problem I have is the Jog function does not operate the VFD at the Jog Speed 20 Hz programmed in F_9?
When activated, the Jog Button operates the motor at 30 Hz, not 20 Hz? (30 Hz is the lower frequency limit.)
Do I have a programming or wiring problem? Or is this the expected behavior of the FM50?
The Jog frequency is set in F_9 = 20. The lower motor speed limit is set in F_7 = 30
The Jog button is a normally open switch when closed sends 12 VDC to position #6 SP1 on the VFD.
SP1 is programmed in F_19 = 1 for the Jog function. When closed, the Jog Button also sends 12 VDC to VFD Position #3 Forward, which is the direction to jog.
I also set the SP1 frequency in F_8 = 20.
Any help is appreciated,
Frank
