Seeing that I am here....

So, is it impossible to do a proper EStop with a Huanyang VFD?

The manual states: no contractor.
Connecting RST to DCM, with PD046 set to 4 (stop) will apparently NOT stop if either the RS485 or user input is active.
I've heard about problems with the EStop restarting when power is reapplied.

(Thanks, as it is a safety thing.)

[I am otherwise considering two sets of contacts on a 15A industrial relay.]
This rots, my body or my warranty. Sigh.]
