(2) When function code E45 data (LCD monitor item selection) is set to "1"
The LCD monitor displays the reference speed (final), output current, and reference torque in a bar chart.
(The lower indicators show the running status and run command source. For the upper ones, see Section
3.3.3.)
The full scale (maximum value) for each item is as follows:
Reference speed (final):
Maximum speed
Output current:
200% of inverter rated current
Reference torque:
200% of motor rated torque

Switching between remote and local modes
The inverter can be operated either in remote or local mode. In remote mode, which applies to normal operation,
the inverter is driven under the control of the data settings stored in the inverter, whereas in local mode, which
applies to maintenance operation, it is separated from the control system and is driven manually under the
control of the keypad.
•
Remote mode: The run and speed command sources are determined by source switching signals including
function codes and communications link operation signal. The keypad cannot be used as a
command source.
•
Local mode:
The keypad is enabled as a run and speed command source, regardless of the settings
specified by function codes. The keypad takes precedence over a communications link
operation signal or other command sources.
Holding down the
key for at least one second switches between remote and local modes. Switching to
remote mode turns on the lower indicator above the REM index, and switching to local mode, above the LOC
index.
When the mode is switched from remote to local, the reference speed (pre-ramp) specified in remote mode is
automatically inherited. Further, if the run command is ON at the time of the switching, the inverter automatically
turns on such a run command in the keypad that carries over the rotational direction.
Figure 3.5 Transition between Remote and Local Modes
In local mode, operation (such as issuing run or speed command) on the remote side is disabled. Do not switch from
remote to local mode while the motor is loaded.
Accidents or injuries may result.
