Teaching Address Over

(n+15, 15/n+23, 15)

A Teaching Address Overflow Flag will turn ON if the teaching address is not

within the range of position data addresses allocated to the task after execut-

ing a Teaching Command (17E2 to 17E5 hex) for the Command Area using

the IOWR instruction in the ladder diagram or after turning ON the Teaching

Bit (one for each task: n+3, 09, n+7, 09, n+9, 09).

The above error can occur at the following times.

• The teaching address set for IOWR is not within the range of position data

• The following condition was not met when turning on the Teaching Bit.

(Current teaching address + Number of axes in task) must be within the

position data range for the task. (The current teaching address is set in

the Command Area, the number of axes in the task is set in the unit

parameters, and the task position data range is set in the memory man-

agement parameters.)

The position data address range has been exceeded.

Teaching has been completed normally either via the Teaching Bit or the

IOWR instruction. (See note.)

Note The Teaching Address Overflow Flag will not be refreshed immediately after

the IOWR instruction is executed. Check the flag status in the next cycle.
