9.2.9 Setting Frequency Command by Program Operation Function EzSQ
 How to set the frequency command from a program created with the program operation
function EzSQ?
 To set the output frequency command using the program operation function EzSQ, set the
"Frequency input source selection [A001]
*1
" to "Program function (EzSQ) (07)". This allows
frequency command to be set at any time according to <SET-Freq> reserved variable within an
EzSQ program.
 The "EzSQ enable selection [A017]" setting can be changed to select whether the EzSQ program
is initiated when the inverter is turned on or when the "Program RUN [PRG] (82)" input terminal
assigned to one of the input terminals [1] to [7] is turned on.
 For details regarding the program operation function EzSQ, refer to "12.2 Program Operation
Function EzSQ".
 To create an EzSQ program and upload it to the inverter, the Inverter setting software
ProDriveNext must be installed on a Windows PC.
 For details, refer to "Inverter configuration software ProDriveNext instruction manual
(NT8001*X)" and "Easy-Sequence Function (EzSQ) Programming Guide (NT2021*X)". For each
guide, please contact the supplier where this device was purchased or local Hitachi inverter
sales office.
