Auxiliary Area Allocations by Function
Name
Inverter Fre- This word contains the automatically calculated fre-
quency Com- quency command value for the inverter.
mand Value
Data range: 0000 to FFFF hex (0.00 to 655.35 Hz) (0.01-
Hz increments, unsigned)
Set the Power Supply Frequency for One Motor Revolu-
tion per Second, Number of Encoder Pulses for One
Motor Revolution, and Error Counter Cycle in the PLC
Setup before using this value.
Present Value of These words contain the present value of the unsigned
Unsigned Output output value (output value = present value of error
counter × error counter cycle (s) × gain).
Value
Data range: 0000 0000 to 8000 0000 hex
(0 to 2,147,483,648)
The maximum and minimum output values are applied.
Present Value of These words contain the present value of the signed out-
put value (output value = present value of error counter ×
Signed Output
error counter cycle (s) × gain).
Value
Data range: 8000 0000 to 7FFF FFFF hex
( − 214,748,348 to 214,748,347)
The maximum and minimum output values are applied.
Operation Com- This flag turns ON during an inverter positioning opera-
mand Flag tion command.
ON: Operation command executed.

Reverse Opera- This flag turns ON during an inverter positioning reverse
tion Command operation command.
Flag
ON: Reverse command in progress
OFF: Forward command in progress or stopped
In-position Flag This flag turns ON when inverter positioning is in position.
ON: In position
OFF: Not in position
