Error Counter
Error Flag This flag turns ON when an error occurs in the error
counter for inverter positioning.
ON: Error counter error
OFF: No error 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
error is reset.
• Turned ON when pulse output to
error counter is stopped and abso-
lute value of error counter present
value is greater than or equal to
error counter error detection value.
Error Counter
Pulse Output Flag This flag is ON while pulses are being output to the out-
put counter for inverter positioning.
ON: Pulses being output
OFF: Pulse output 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
error is reset.
• Turned ON when pulse output to
error counter is stopped and abso-
lute value of error counter present
value is greater than or equal to
error counter error detection value.
Error Counter
Pulse Output
Accelera-
tion/Deceleration
Flag This flag is ON while pulse output to the output counter
for inverter positioning is accelerating or decelerating.
ON: Pulse output to the error counter is accelerating or
decelerating (i.e., the frequency is changing)
OFF: Pulse output to the error counter is constant 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 during output of a con-
stant pulse frequency to error
counter.
• Turned OFF when pulse output to
error counter is stopped (including
immediate stops and deceleration
stops).
• Turned ON when pulse output fre-
quency to error counter is changed
by ACC or PLS2 instruction.
Error Counter
Alarm Flag This flag turns ON when an alarm occurs in the error
counter for inverter positioning.
ON: Error counter alarm
OFF: No alarm 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
alarm is reset.
• Turned ON when pulse output to
error counter is stopped and abso-
lute value of error counter present
value is greater than or equal to
error counter alarm detection
value.
Inverter Position-
ing Output Value
Sign Flag This flag is ON when the inverter positioning output value
is positive and is OFF when it is negative.
ON: Positive value
OFF: Negative value Read • Turned ON when signed output
value is between 0000 0000 and
7FFF FFFF hex.
• Turned OFF when signed output
value is between FFFF FFFF and
8000 0000 hex.
Error Counter
Present Value,
Signed This word contains the present value of the error counter.

Bit (A562.01) is turned ON.
• Updated each error counter cycle.
Present Value of
Pulse Output to
Inverter, Relative
Value These words contain the relative value of the internal
pulse output value when pulses are being output to the
error counter.
Data range: 8000 0000 to 7FFF FFFF hex
(

2,147,483,648 to 2,147,483,647)
Read • Cleared when power is turned ON.
• Cleared when operation starts.
• Cleared when pulse output to error
counter is started.
• Updated each error counter cycle.
