Pretty sure this is avoidable by using the Triple Beasts charge pump feature

Yes.
Chargepump needs to be enabled on Benezan Boards than everything works as it should.
With removed JP2 jumper, the Chargepump becomes active, and outputs only go high when F2 is pressed to toggle the Machine power.
So once F2 is pressed both relays go high and both leds come up.
So to keep both relays unactive until we enable them, following needs to be added to hal file.

Example shown for connection through onboard Connector P1

# --- BENEZAN RELAY1 PIN-1 ---
setp hm2_7i92.0.gpio.017.is_output true

# --- BENEZAN RELAY2 PIN-14 Coolant/mist ---
setp hm2_7i92.0.gpio.018.is_output true

and then trigger them when needed with:
net spindle-cw => hm2_7i92.0.gpio.017.out
net coolant-mist => hm2_7i92.0.gpio.018.out

No need for inverted relays, or secondary relays or other boogie woogie :)

and if possible the settings of the parameters you changed on the VFD


Hal and ini files were attached few posts back, regarding the parameters on VFD, that's not same on all VFD's I think.
I do have Omron MX2 from Sorotec, and if looking at manuals there are settings from A011 to A015 which do set frequency range in Hz and also input range in %.
As I have now set my frequency from 100-400, so I set the % parameters from 26 to 100% , so spindle does not turn on if PMW sends lower signal than needed for 100Hz or 6000rpm.

My Omron MX2 settings:
A011 - 100
A012 - 400
A013 - 26
A014 - 100
A015 - 00

.hal setting for the spindle on Benezan board
# --- BENEZAN RELAY1 PIN-1 ---
setp hm2_7i92.0.gpio.017.is_output true

# --- BENEZAN PWM PIN-17 and add OUTPUT_SCALE = 24000.0 to .ini file---
net spindle-cw hm2_7i92.0.gpio.017.out
net spindle-vel-cmd-rpm => hm2_7i92.0.pwmgen.01.value
net spindle-enable => hm2_7i92.0.pwmgen.01.enable
setp hm2_7i92.0.pwmgen.01.output-type 1
setp hm2_7i92.0.pwmgen.01.scale [SPINDLE_0]OUTPUT_SCALE

.ini settings for spindle on Benezan board
# BENEZAN SPINDLE My output scale
OUTPUT_SCALE = 24700.0

I have the output scale to 24700 as it better rounds the frequency among 100-400 range on Benezan BOB.
