Switching of Command Input Device

(1) Frequency source setting (A001 / A201)

Selection of the device used to input frequency commands follows the frequency source setting (A001 / A201), 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 / A201). Otherwise, the frequency setting in "SET-Freq" will not be reflected in the inverter.
A201 is available for only WJ200 series. SJ700, L700 and SJ700B series do not correspond.
Function code
A001 / A201

(2) Run command source setting (A002 / A202)

Selection of the device used to input operation commands follows the run command source setting (A002 / A202), 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 / A202) to enable the use of
the variables.
A202 is available for only WJ200 series. SJ700, L700 and SJ700B series do not correspond.
Function code
A002 / A202

(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 / A201 = 07.
Remarks
The use of program variables
"FW", "RV", "STA", "STP",
and "F/R" is enabled only when
A002 / A202 = 01.
Remarks
The use of program variables
"ACCEL" and "DECEL" is
enabled only when P031 = 03.
