Mitsubishi Electric MEsoftstart/I01 Users, Installation & Instruction Manual page 89

On the Pro variants:
Once the MEsoftstart PC App (or other Modbus controller) is connected, the soft starter TFT display will not accept command
inputs (other than to toggle through the Parameter Display Area options). This will be clear to the user with the yellow text
"TCPCTL" being displayed in the top right side of the TFT display – refer Figure 39.
To return control to the TFT display on the soft starter, close the PC application or disconnect the Modbus cable. After a delay
of about 10 seconds, the TFT display will allow user inputs again.
Note that after power-up, the soft starter will only service the Modbus port once the configuration has been accepted on the
TFT display. If the MEsoftstart PC App shows that it has the communication port open but is not receiving data from the soft
starter (refer Figure 50), check the TFT display on the soft starter and accept the configuration. Once this is done, the soft starter
should commence Modbus communication and the Start screen (Figure 51) should be visible.
On the Core variants:
Once connected the MEsoftstart/I Core variant Mode LED will flash faster (1Hz) to indicate that Modbus monitoring and Control
is possible. Limited configuration is also possible (refer paragraph 5.2.1
Do not attempt to immediately start the motor – first view the configuration and confirm that the settings are correct
for the user's installation.
Configuring start and stop behaviour using the MEsoftstart PC App
On the Core variant:
Configuration is mostly done on the Potentiometer HMI – refer paragraph 5.2 above. The configuration that the soft starter
reads from the HMI inputs may be viewed on the MEsoftstart/I Core PC Interface Application. In addition, advanced settings may
be configured from the PC Application. Figure 52 shows a typical configuration screen for the Core model. Note how the 'Ramp-
up time', 'Maximum Starting Current Percentage', 'Rated Current' etc. values are displayed but the fields are inactive for editing
since these parameters are set on the potentiometers on the HMI panel.
