Pulse Input to Control a Spindle

[Kittifix]

I have this Information about the VFD
Possible to Control with 6HC ?

@Kittifix
I think that the encoder input/pulse input from an encoder should be used as a feedback loop and not as a control input.

If you are referring to the following datasheet https://assets.danfoss.com/documents/latest/271209/AQ276736419659en-000101.pdf
you may have a look into https://files.danfoss.com/download/Drives/MG02K402.pdf
And you could either use RS485 or use the 0-10V Interface with an PWM to Voltage Converter PCB.

All sources for the speed controls are listed in menu 3
under 3-15 Reference Resource 1 is [8] Pulse input 33 listed as a source
Why can't I use this?

@Kittifix you are maybe able to use it, but RRF is able to create a spindle with an PWM output for the speed control.

If you use a PWM to Freqency Converter PCB you will maybe able to use the pulse input.
