Function
This flag will be ON when pulses are being output from pulse out-
put 1 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
This flag indicates when an overflow or underflow has occurred in
the PV of pulse output 1.
OFF: Normal, ON: Error
ON when the number of output pulses for pulse output 1 has been
set with the PULS(886) instruction.
OFF: Not set, ON: Set
ON when the number of output pulses set with the PULS(886),
PLS2(887), or IFEED(892) instruction has been output through
pulse output 1.
OFF: Output not completed, ON: Output completed
ON when pulses are being output from pulse output 1.
OFF: Stopped, ON: Outputting
ON when the origin has not been determined for pulse output 1
and goes OFF when the origin has been determined.
OFF: Origin established, ON: Origin not established
ON when the PV of pulse output 1 matches the origin (0).
