Additional info about YL620-A

I recently purchased a YL620-A 1.5kW VFD with 24,000 RMP spindle.
While I’m quite happy with the basic function of the VFD, I seem to be missing some important data about the control terminals.
I have searched the manual that came with the device and also the internet for further info but could not find what I was looking for.

So here are my questions:

* What kind of power can the inbuilt relay (CM1-NO1-NC1) switch - voltage/amperage for AC and DC respectively?
* What is the maximum load (amperage) the 13V external power supply can provide?
* When measuring the voltage between XVcc and XGnd why do I see 15V although it is called "external INPUT 15V"?
* Can I power external devices from XVcc?
* If so, what maximum load (amperage)?
* What signal do AO and MO provide exactly - what are they for?

As a side question:
* Would it be possible and safe to power an SMC5-5-n-n from the YL620-A via the 13V/GND terminals?

Thanks
