B–62073E–1/04 2. INTERFACE BETWEEN CNC AND PMC–NA OR NB
– 343 –
5 This function cannot be applied to an axis for which any of the following functions is used.
– PMC axis control
– Simple synchronous control
– Straightness compensation
6 This function is invalid when any of the following conditions is satisfied:
– Either parameter No. 1896 (mark 1 interval) or No. 5226 (mark 2 interval) is set to 0.
– Parameters No. 1896 and No. 5226 are set to the same value.
– Parameter No. 1896 is set to a value two or more times greater than the value set with parameter
No. 5226, or vice versa.
– A rotary axis is specified.
Reference position established signals
[Classification]
Output signal
[Function] Indicates that the CNC has established the reference position by means of reference position
return.
NOTE 1 Some machines use an absolute pulse coder to establish the reference position upon
power–on. In the case of such a machine, this signal is output upon power–on.
NOTE 2 When a linear scale having reference marks is used, this signal is output once three or four
reference marks have been detected during the establishment of the reference position.
[Operation] This signal is set to 1 once the CNC has established the reference position by means of refer-
ence position return. The state of 1 is maintained until the CNC loses the reference position.
