<Description>
• In the pulse generation mode, when the first interrupt signal is detected after this signal has become “1,” the bit
data signal for interrupt signal detection becomes “1.” At the same time, the deviation amount data or the lower
word of the current value counter when the interrupt signal was detected is output in the current value data area
(address No. 3).
When this signal becomes “0,” the bit data for interrupt signal detection returns to “0.”
At the same time, the upper word of the current value counter is output in the current value data area (address No.
3).

(1) Not detected because interrupt position detect command is “0.”
(2) Not accepted because interrupt signal is already detected.
(3) Deviation amount when the interrupt signal was detected
(4) The lower word of the current value counter when the interrupt signal was detected
• In the position command mode, the select function of the interrupt point positioning mode is disabled, but the
interrupt position detect function is enabled.
Precaution:
Deviation amount is the signed data.
In this module, the deviation amount is calculated using 32-bit signed data. When the deviation amount exceeds
32,767 pulses, “-32,768” is output as the deviation amount when the interrupt signal is detected.
(Because current value data area is of one word length.)
