Drive Programming Start/Stop and Task Operation

You set the start/stop method of the Drive Programming programs in the Drive Programming Function
Selection (A017).
 Start
• When the Drive Programming Function Selection (A017) is set to 01 (Enabled: Start/stop via
multi-function input PRG terminal):
The program starts when the multi-function input terminal set to PRG is turned ON.
• When the Drive Programming Function Selection (A017) is set to 02 (Enabled: Start/stop at power
on/off):
The program starts when the power supply for the inverter is turned ON.
 Stop
• When the Drive Programming Function Selection (A017) is set to 01 (Enabled: Start/stop via
multi-function input PRG terminal):
The program stops when the multi-function input terminal set to PRG is turned OFF.
• When the Drive Programming Function Selection (A017) is set to 02 (Enabled: Start/stop at power
on/off):
The program stops when the power supply for the inverter is turned OFF.
Also, regardless of the A017 setting, the Drive Programming program stops if any of E43 to E45 trips is
detected due to a program error, or when the "end" command is executed in all tasks.
Precautions for Safe Use
When 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.
