MELSEC-Q

(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.
