Inverter Fre-
quency Com-
mand Value This word contains the automatically calculated fre-
quency command value for the inverter.
Data range: 0000 to FFFF hex (0.00 to 655.35 Hz) (0.01-
Hz increments, unsigned)

Operation Com-
mand Flag This flag turns ON during an inverter positioning opera-
tion command.
ON: Operation command executed.
OFF: Stop command executed. Read • Turned OFF when power is turned
ON.
• Turned OFF when operation starts.
• Turned OFF when CPU Unit opera-
tion stops.
• Turned OFF when inverter posi-
tioning is stopped (immediate stop)
using INI instruction.
Forward Operation
Command Flag This flag turns ON during an inverter positioning forward
operation command.
ON: Forward command in progress
OFF: Reverse command in progress or stopped Read • Turned OFF when power is turned
ON.
• Turned OFF when CPU Unit opera-
tion starts.
• Turned OFF when CPU Unit opera-
tion stops.
• Turned OFF when error counter
present value is 0 or less than 0
(negative).
• Turned ON when error counter
present value is greater than 0
(positive).
Reverse Opera-
tion Command
Flag This flag turns ON during an inverter positioning reverse
operation command.
ON: Reverse command in progress
OFF: Forward command in progress or stopped Read • Turned OFF when power is turned
ON.
• Turned OFF when CPU Unit opera-
tion starts.
• Turned OFF when CPU Unit opera-
tion stops.
• Turned OFF when error counter
present value is 0 or greater than 0
(positive).
• Turned ON when error counter
present value is less than 0 (nega-
tive).
In-position Flag This flag turns ON when inverter positioning is in position.
ON: In position
OFF: Not in position Read • Turned OFF when power is turned
ON.
• Turned OFF when CPU Unit opera-
tion starts.
• Turned OFF when CPU Unit opera-
tion stops.
• Turned OFF when pulses are being
output to error counter.
• Turned OFF absolute value of error
counter present value is greater
than in-position range.
• Turned OFF when pulse output to
error counter is stopped and abso-
lute value of error counter present
value is less than in-position range
