Parameter
Switch-over mode (Pr. 79 = 6)
While continuing operation, you can switch between the PU operation, external operation and net-
work operation (when RS-485 communication with the PU connector or communication option is
used).

Tab. 6-54: Operation states in the switch-over mode
WARNING:
P
When using switch-over mode please note that in some switch-over operations the rotation
direction command and the frequency setting value are "transferred" to the "new" operating
mode (refer to Tab. 6-54 for details). When this happens the drive will run in the new operating
mode even though it has not (yet) received any control commands.
It is extremely important to take this into account and take the necessary steps to ensure that
performing these switch-over operations cannot cause hazardous conditions.

Switching Operation/Operating Status
PU operation Select the PU operation mode with the operation panel or parameter unit.
Rotation direction is the same as that of external operation.
The frequency set with the potentiometer (frequency command) or like is
used unchanged. (Note that the setting will disappear when power is
switched off or the inverter is reset.)
NET operation Send the mode change command to the network operation mode through
communication.
Rotation direction is the same as that of external operation.
The value set with the setting potentiometer (frequency command) or like
is used unchanged. (Note that the setting will disappear when power is
switched off or the inverter is reset.)
external operation Press the external operation key of the parameter unit.
The rotation direction is determined by the input signal of the external
operation.
The set frequency is determined by the external frequency command
signal.
NET operation Send the mode change command to the network operation mode through
communication.
Rotation direction and set frequency are the same as those of PU operation.
external operation Command to change to external mode is transmitted by communication.
Rotation direction is determined by the external operation input signal.
The set frequency is determined by the external frequency command
signal.
PU operation Select the PU operation mode with the operation panel or parameter unit.
The rotation direction and frequency command in the network operation
mode are used unchanged.
