Function
ON when the origin has not been determined for pulse output 2
and goes OFF when the origin has been determined.
OFF: Origin established, ON: Origin not established
ON when the PV of pulse output 2 matches the origin (0).
OFF: Not stopped at origin, ON: Stopped at origin
ON when an error occurred while outputting pulses in the pulse
output 2 origin search function. The Pulse Output 2 Output Stop
Error Code will be written to A438.
0: No error, ON: Stop error
These flags are turned ON when an interrupt input is received
after output from pulse outputs 2 to 3 is started with the
IFEED(892) instruction.
OFF: Interrupt feeding not in progress.
ON: Interrupt feeding in progress.
This flag will turn ON if an overflow or underflow occurs when an
interrupt input is received, or when the specified number of pulses
is moved, after output from pulse outputs 2 is started with the
IFEED(892) instruction.
OFF: Overflow/underflow or specified number of pulses has been
moved.
ON: No error.
This flag will be ON when pulses are being output from pulse out-
put 3 according to an ORG(889), ACC(888), PLS2(887), or
IFEED(892) instruction and the output frequency is being
changed in steps (accelerating or decelerating).
OFF: Constant speed, ON: Accelerating/decelerating
