DriveProgramming Start/Stop and Task Operation

You set the start/stop method of the DriveProgramming programs in the EzSQ function enable (UE-02).
 Start
• When the EzSQ function enable (UE-02) is set to 01 ([PRG] terminal),
The program starts when the input terminal set to PRG is turned ON.
• When the EzSQ function enable (UE-02) is set to 02 (Always),
The program starts when the power supply for the inverter is turned ON.
 Stop
• When the EzSQ function enable (UE-02) is set to 01 ([PRG] terminal),
The program stops when the input terminal set to PRG is turned OFF.
• When the EzSQ function enable (UE-02) is set to 02 (Always),
The program stops when the power supply for the inverter is turned OFF.
Also, regardless of the UE-02 setting, the DriveProgramming program stops if any of E043 to E045
trips is detected due to a program error, or when the "end" command is executed in all tasks.
Precautions for Safe Use
When the DriveProgramming program is stopped, the output terminal controlled by the Drive-
Programming retains the status before the program stop.
For this reason, configure the system so that the stop of the DriveProgramming program in the
inverter can be detected by the DriveProgramming start signal and the alarm (trip) signal, and
the inverter's peripheral devices can be stopped safely.
Precautions for Correct Use
The following are the status of function variables when the DriveProgramming program is
stopped. Take necessary measures in consideration of each status.
• For the output terminals (the inverter's actual output terminals), the status before the program
stop is retained.
However, the output terminals that are not set to MO1 to MO6 (general-purpose outputs of
the DriveProgramming) operate as the inverter's normal output terminals.
• When the DriveProgramming function is selected for the frequency reference, accelera-
tion/deceleration time or analog outputs, the set values for these functions before the pro-
gram stop are retained.
• The data of the user parameter variables, internal user variables and internal user contacts
before the program stop is retained.
• The status of the inverter's actual input terminals such as the input terminal and analog input
terminals is not retained but always updated.
• The data of the output variables (function bits such as RUN, FA1 and AL) and inverter moni-
tor variables is not retained but always updated according to the status of the inverter.
• Only the DriveProgramming's input variables (function bits such as FW, RV and CF1) and
timer variables are cleared at the same time as the program stop, and all data are changed to
zero.
When the DriveProgramming function is started/stopped through the CX-Drive, the value of the
inverter parameter, the EzSQ function enable (UE-02) is changed.
Take the following measures after you started/stopped the DriveProgramming function through
the CX-Drive.
