Precautions for Safe Use
When the DriveProgramming program is stopped, the output controlled by the DriveProgram-
ming 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 MO7 (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, EzSQ function enable (UE-02) is temporarily changed to 02 (start) or 00
(stop) only in the RAM data.
Take the following measures after you started/stopped the DriveProgramming function through
the CX-Drive.
• Turn ON the power supply for the inverter again and return the value of UE-02 to that saved
in the EEPROM.
• Do not perform the following EEPROM saving operations before you turn ON the power sup-
ply for the inverter.
• Transferring (downloading) a part of parameters from the CX-Drive.
• Issuing the "enter" command via the Modbus communication or a communication option.
When UE-02 is set to 02, stop the running program that was started at power ON before you
restart the program via the CX-Drive.
If any program that was started at power ON is running, the CX-Drive cannot restart the program.
In the CX-Drive, if you click the button to start the program when inverter is already in opera-
tion, the following message will be displayed in the final step.

Description
When EzSQ function enable (UE-02) is set
to 01 ([PRG terminal] (Start/stop via input
terminal PRG), the program is started via the
input terminal with this setting.
