4.2.104 Easy sequence function

- You can create a user program with EzSQ (the programming software dedicated to the SJ700) on a personal computer, and download the program to your

SJ700 series inverter. Thus, you can convert your inverter to a special machine on which user-defined functions are installed. Please refer to programming instruction of EzSQ user manual.

-The easy sequence function does not provide an operation mode exclusive for program-based operation. Therefore, you can arbitrarily select the devices to input frequency and operation commands to the inverter. On the other hand, the FW terminal must be used exclusively to run the program. If the control circuit terminal block is specified as the device to input operation commands, the FW terminal must be turned on by an instruction in the program.

-The intelligent input/output terminals of the inverter include general-purpose input/output terminals dedicated to the easy sequence function. Those terminals can be used to freely write and read data to and from the inverter with instructions in the program.

-You can assign the parameters (e.g., frequency setting and acceleration/deceleration time parameters) that require adjustments on the actual inverter to user parameters (P130 to P131). If you do so, you can readjust the parameter data by using the digital operator without having to connect your personal computer to the inverter.

-If you specify a program number in each program you created, you will be able to check the program number on the monitor of the digital operator.

-Each user program is compiled, and stored as an intermediate code in the internal EEPROM of the inverter. (Data can be stored in EEPROM.)

-Even if the user data is initialized via the digital operator, downloaded programs and user parameters (P100 to P131) are not cleared.

-You cannot copy the downloaded program by an operation from a remote operator. You cannot copy the user parameter codes "P***", either. If necessary, download the user parameter codes from your personal computer.
