Replacement of out of production inverter

Need help with why a replacement inverter will not respond to control signals
I am replacing failed inverter vfd015s21u(now no longer in production) with indicated replacement inverter VFD7A5MS21ANSAA . the new inverter does not respond to the controls on the lathe it is attached to. It does respond to the RUN and STOP button on the inverter digital panel.

The interface consists of:
digital ground for the two above items

+10 volts and analog ground

I am checking to see what I can find out for you.
