9.4 Stopping and Restarting in N/M AUTO Mode
There are three ways of inhibiting an axis that has been declared as uninterpolated.
Case 1
The part programme contains parameter E912xx=0. The N/M AUTO function
remains enabled, but axis xx becomes interpolated.
%R2.1 (E_NMAUTO) remains high.
If the NMA axis is being moved (by handwheel or jogs), programme execution
resumes once the axis has stopped.
Case 2
The PLC programme resets %W2.1 (C_NMAUTO) and the INCYC LED is unlit. This
completely inhibits the N/M AUTO function.
%R2.1 (E_NMAUTO) goes low.
Error 107 is generated if the next block defines a circle. However, parameters E912xx
remain unchanged but are ignored.
To reenable the N/M AUTO function, it is not necessary to set parameters E912xx
explicitly to 0 then to 1.
When the PLC programme sets %W2.1 (C_NMAUTO) from 0 to 1, and as soon as
the INCYC LED goes out and/or the CYHLD LED comes on, the N/M AUTO function
is reenabled immediately and:
- parameters E912xx that are set become operative
- %R2.1 (E_NMAUTO) goes high.
Case 3
The PLC programme resets %W2.1 (C_NMAUTO) when the CYHLD LED is lit. The
AXRCL LED comes on and the NMA axes must be recalled before continuing the part
programme.
The N/M AUTO function is completely inhibited.
%R2.1 (E_NMAUTO) goes low.
However, parameters E912xx remain unchanged but are ignored.
To reenable the N/M AUTO function, it is not necessary to set parameters E912xx
explicitly to 0 then to 1.
When the PLC programme sets %W2.1 (C_NMAUTO) from 0 to 1, and as soon as
the INCYC LED goes out and/or the CYHLD LED comes on, the N/M AUTO function
is reenabled immediately and:
- parameters E912xx that are set become operative
- %R2.1 (E_NMAUTO) goes high.
REMARK A reset returns all the axes to interpolated state (E912xx=0).
