<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 at the moment the interrupt signal was detected is output in current value data
area 2.
When this signal becomes “0,” the bit data for interrupt signal detection returns to “0.”
At the same time, the upper word of current value counter is output in current value data area 2.

1) Not detected because the interrupt position detect command is “0.”
2) Not accepted because the interrupt signal has already been detected.
3) Deviation amount when the interrupt signal was detected
4) The upper word of the current value counter when the interrupt signal was detected
• In position command mode, the select function of interrupt point positioning mode is disabled, but the interrupt
position detect function is enabled.
Precaution:
Deviation amount is 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 interrupt
signal is detected.
(Because current value data area is of one word length.)
