Precautions for Safe Use
When execution of the Drive Programming program is stopped, the status before the program
stop is retained for multi-function outputs controlled by the Drive Programming.
For this reason, configure the system so that the stop of the Drive Programming program in the
inverter can be detected by the Drive Programming 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 Drive Programming program is
stopped. Take necessary measures in consideration of each status.
• For the multi-function outputs (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 Drive Programming) operate as the inverter's normal multi-function outputs.
• When the Drive Programming 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 multi-function and analog input
terminals is not retained but always updated.
• The data of the multi-function output variables (function bits such as RUN, FA1 and AL) and
inverter monitor variables is not retained but always updated according to the status of the
inverter.
• Only the Drive Programming's multi-function 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 Drive Programming function is started/stopped through the CX-Drive, the value of the
inverter parameter, Drive Programming Function Selection (A017) is temporarily changed to 02
(start) or 00 (stop) only in the RAM data.
Take the following measures after you started/stopped the Drive Programming function through
the CX-Drive.
• Turn ON the power supply for the inverter again and return the value of A017 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.

(Drive Programming start)
Description
When the Drive Programming Function
Selection (A017) is set to 01 (Enabled:
Start/stop via multi-function input PRG termi-
nal), the program is started via the
multi-function input terminal with this setting.
