Pot and switch types for remote VFD

[CluelessNewB]

The parameters pd071 thru pd076, how would these affect the operation of the 10K pot?

PD071 Analog Filtering Constant:

This is probably just fine set at the default of 20 or higher. This will control how fast the VFD responds to changes of the analog control signal, this not really an issue with manual controls but might be if an external sensor was used.

PD072 Higher Analog Frequency:

PD072 will limit the maximum speed your motor will go. It's a frequency so if your motor is normally rated at 60 cycles per second and runs at 3600 rpm and that is the maximum speed you wan to run it this should be set to "60.00". If you wanted to run it at 5400 rpm (1.5 x3600) you would set PD072 to "90.00" (1.5x60)

PD073 Lower Analog Frequency:

PD073 will limit the minimum speed your motor will go. You can leave this at the default 0

PD074 - PD076 I would leave these at the default 0

Truthfully I can make a semi-educated guess at what they do but the manual is severely lacking in a good description.

To add to CluelessNewB's information (thanks!), my spindle runs at a maximum of 24,000 RPM, so 400 is my choice (60x400=24000) for PD072.

Excellent explanation! Thank you.
