OPERATION USING THE KEYPAD
3.3.8 Switching between local and remote modes
When performing normal operation, the motor runs in the remote mode with the operation method set at the inverter,
and when performing maintenance, it is possible to switch to the local mode used for performing operation with the
keypad. In local mode, the inverter is isolated from the system. In this mode, the inverter is run, and the necessary
work is carried out by performing all operations from the keypad.
∙ Remote mode: Run and frequency commands are selected by function codes or source switching signals
except LOC (“Select local (keypad) command”).
If the / is pressed while in remote mode, “3.3.10 Display when keypad operation disabled
(command source display)” is displayed for 2 seconds.
∙ Local mode: The command source is the keypad, regardless of the settings specified by function codes. The
keypad takes precedence over the settings specified by communications link operation signals.
The KEYPAD CONTROL LED blinks once every second while in local mode.
The table below shows the input procedures of run commands from the keypad in the local mode.
Input procedures of run commands from keypad
0: Keypad operation
(Rotation direction input:
Terminal block)
The motor can be run and stopped by pressing the keypad /
keys.
The rotation direction is specified with terminals [FWD] and [REV].
The motor can be run and stopped by pressing the keypad /
keys.
There is no need to specify the rotation direction.
However, the motor cannot be rotated in the reverse direction if only
forward rotation is specified.
2: Keypad operation
(forward rotation)
3: Keypad operation
(reverse rotation)
The motor can be run and stopped by pressing the keypad /
keys.
There is no need to specify the rotation direction.
However, the motor cannot be rotated in the forward direction if only
reverse rotation is specified.
The following two methods can be used to switch between remote mode and local mode.
1. Assign data = 35
LOC
to function code E70, and hold down the key on the keypad.
2. Assign data = 35
LOC
to any of the function codes E01 to E09, E98, or E99, and turn on the applicable digital
input terminal.
Switching from remote to local mode automatically inherits the frequency settings used in remote mode.
If the motor is running at the time of the switching from remote to local, the keypad run command will be
automatically turned ON so that all the necessary data settings will be carried over.
If, however, there is a discrepancy between the settings used in remote mode and ones made on the keypad (e.g.,
switching from the reverse rotation in remote mode to the forward rotation only in local mode), the inverter
automatically stops.
Status transition and the operation status differ based on the remote/local status, and the local (keypad) command
selection LOC signal combination. Also, refer to above table for details.
