16.3.2 EzSQ use procedure
■
Flow up until execution of EzSQ
No.
Create an EzSQ program with "ProDriveNext".
1
Compile the program in the form executable in the inverter.
2 As soon as the compiling begins, the grammar of EzSQ program is checked. If
there is an error, the compiling is suspended and the error message appears.
Download the compiled EzSQ program to the inverter and save it to the
3
memory element of inverter.* 1)
4 Set necessary parameters for the inverter.
5 Set the EzSQ function selection [UE-02] to Enable (01 or 02).
When UE-02 is set to 01, the PRG terminal is turned ON and the program will
be executed.
6
When UE-02 is set to 02, the program will be executed automatically after the
power supply is turned ON. 2)
7 The operation state of EzSQ can be checked on the inverter operator keypad.
!
*1) By saving the program to the memory element
incorporated in the inverter (data flash), you will also be
able to execute the program after the power supply is
re-turned ON. If the downloaded program hasn't been
saved to the memory element, the program will be
erased when the inverter power supply is shut off.
When you create a program and carry out debugs
including operation check, it is recommended to save
after the debugs are completed instead of saving to the
memory element.
*2) Once the program is downloaded to the inverter, the
EzSQ program becomes executable with the inverter
disconnected from the PC.
Description
• Because SJ-P1 doesn't share the same parameter
numbers, setting range, the minimum unit, etc. with
conventional models like SJ700/L700, the EzSQ
programs created for these conventional models may not
be used as is. Make sure to carry out re-examination of
the programs and operation checks.
• When a reset or trip reset using the RS terminal is
performed during execution of an EzSQ program, the
program counter will be reset and the program will be
executed from the lead.
