Chapter 13 Control Sub Functions
[2] Precautions during control
(1) Before teaching, a "machine OPR" must be carried out to establish the OP.
(When a current value changing, etc., is carried out, "
Md.20
Current feed
value" may not show absolute addresses having the OP as a reference.)
(2) Teaching cannot be carried out for positions to which movement cannot be
executed by manual control (positions to which the workpiece cannot
physically move). (During center point designation circular interpolation
control, etc., teaching of "
Da.7
Arc address" cannot be carried out if the
center point of the arc is not within the moveable range of the workpiece.)
(3) Writing to the flash ROM can be executed up to 100,000 times.
If writing to the flash ROM exceeds 100,000 times, the writing may become
impossible (assured value is up to 100,000 times).
If an error (error code: 805) occurs when writing to the flash ROM has been
completed, check whether or not the program is created so as to write
continuously to the flash ROM.
