Chapter 6 Interface with the Inverter
6.4 Switching of Command Input Device
6.4.1 Frequency source setting (A001)
Selection of the device used to input frequency commands follows the frequency source setting (A001),
regardless of whether the easy sequence function is enabled.
EzSQ provides variable "SET-Freq" for setting the inverter output frequency. To enable the use of this
variable, specify "07" (PRG) for the frequency source setting (A001). Otherwise, the frequency setting in
"SET-Freq" will not be reflected in the inverter.
Function code
A001
6.4.2 Run command source setting (A002)
Selection of the device used to input operation commands follows the run command source setting
(A002), regardless of whether the easy sequence function is enabled.
EzSQ provides variables "FW", "RV", "STA", "STP", and "F/R" for the inverter control related to operation
commands. Since these variables are handled as terminal input data, specify "01" (TRM) for the run
command source setting (A002) to enable the use of the variables.
Function code
A002
6.4.3 Accel/decel time input selection (P031)
Selection of the device used to input acceleration/deceleration time settings follows the setting of
accel/decel time input selection (P031), regardless of whether the easy sequence function is enabled.
EzSQ provides variables "ACCEL" and "DECEL" for the inverter control related to acceleration and
deceleration time. To enable the use of these variable, specify "03" (PRG) for the accel/decel time input
selection (P031). Otherwise, the acceleration/deceleration time settings in "ACCEL" and "DECEL" will not
be reflected in the inverter.

Remarks
The use of program
variable (SET-Freq)
data is enabled only
when A001 = 07.
Remarks
The use of program
variables "FW", "RV",
"STA", "STP", and "F/R"
is enabled only when
A002 = 01.
Remarks
The use of program
variables "ACCEL" and
"DECEL" is enabled
only when P031 = 03.
