After turning
ON
the
MRS
terminal, if the setting for Pr.79
is
changed to any value other
than '7" in the PU operation mode, the
MRS
terminal functions as the ordinary
MRS
terminal (mechanical reset terminal) instead
of
the edit enable signal terminal. Then the
operation
mode
is changed according to the new setting for Pr.79.
When mode changed is attempted between the external operation mode to the PU
operation mode with the
MRS
terminal
ON,
the mode change will not occur
if
the STF
or STR terminal is
ON.
In the setting
of
Pr.79
=
7 with the
MRS
terminal
ON,
if the
MRS
terminal is turned OFF
while in the PU operation mode, the operation
mode
is changed to
the
external opera-
tion
mode
independent
of
the OWOFF status of the terminal (STF,
STR).
Therefore,
if
the
MRS
terminal
is
turned OFF while either the STF or STR terminal
IS
ON,
the motor
is controlled in the external operation mode.
During the operation in the PU operation mode, the ordinary
MRS
function does not
work.
When the mode is changed from the PU operation mode to the external operation
mode forcibly, the parameter unit is internally reset once
to
secure the monitor screen.
If an alarm has occurred, the inverter can be reset by pressing the stop key in the PU
operation mode. Resetting
of
the inverter in the external operation mode is not possible.
Therefore, resetting the inverter always changes the mode to the PU operation mode.
