Table 3.3 Run Commands from the Keypad in the Local Operation Mode
If function code F02 is set
to:
Setting means of the run command
0: Keypad
1: External signal
You can run/stop the motor using the
/ /
key on the keypad.
2: Keypad (forward)
You can run/stop the motor using the
/
key on the keypad.
You can run the motor in forward direction only. (The key has been disabled.)
3: Keypad (reverse)
You can run/stop the motor using the
/
key on the keypad.
You can run the motor in reverse direction only. (The key has been disabled.)
The source for setting run and frequency commands can be switched between Remote and Local modes by the
key on the keypad. (This key is a toggle switch: Each time you press it for more than 1 second, the mode
switches from Romote to Local or vice versa.)
The mode can be switched also by an external digital input signal. To enable the switching you need to assign
(LOC) to one of the digital input terminals, which means that the commands from the keypad are given
precedence (one of function codes E01 to E05, E98, or E99 must be set to "35"). By factory default, (LOC) is
assigned to [X5].
You can confirm the current mode on the indicators (REM: Remote mode; LOC: Local mode).
When the mode is switched from Remote to Local, the frequency settings in the Remote mode are automatically
inherited. Further, if the inverter is in Running mode at the time of the switching from Remote to Local, the Run
command is automatically turned ON so that all the necessary data settings will be carried over. If, however,
there is a discrepancy between the settings on the keypad and those on the inverter itself (e.g., switching from
reverse rotation in the Remote mode to forward rotation in the Local mode using the keypad that is for forward
rotation only), the inverter automatically stops.
The paths of transition between Remote and Local modes depend on the current mode and the value (ON/OFF)
of (LOC), the signal giving precedence to the commands from the keypad, as shown in the state transition
diagram (Figure 3.5) given below.
For further details on how to set operation commands and frequencies in Remote and Local modes, refer
to the FRENIC-Eco User’s Manual, Chapter 4 "BLOCK DIAGRAMS FOR CONTROL LOGIC" (especially
Section 4.3 “Drive Command Generator” block diagram).
