Hi people , i am learning to drive a Fagor 8T controller on my lathe but keep getting error code today " No Spindle Speed Value"

I have spindle speed set already , its showing on the screen ( 400 RPM ) , it was all working fine yesterday but i have stuffed a setting and cant find which one

The spindle will run okay in manual mode but when i try to start a canned turning cycle the spindle does a few turns then stops with that error message.

The manual doesnt list a reason for it that i can find

---------

I also had another error code "072 following error Z" , i assume it means a coordinate i programmed in Z axis is incorrect but i cant see why ? i have the values entered with correct + and - where they should be
Please tell me what "following error" means ?

eg screenshot

RPM 400 DIAMETER

BEG X=000100.00 , Z= 000200.00
END X=000090.00 , Z= 000100.00

Dia 000090.00
> 0000.300 N 00000

Following Error Z means that there is something causing a lag or prevention allowing the Z axis to reach position or actually move.
Can be a mechanical binding or open encoder.
With most Fagor, the position can be set by parameter for either anticipated position or actual encoder posn. Set to encoder position and move the Z and see if the Z display changes.
