4. Function
The hand-held micro terminal communicates with the
motor control system via Modbus commands.
Factory and user settings are stored in the control system.
The settings are preserved in the memory even if the line
voltage is switched off or if the hand-held micro terminal
is removed.
If the hand-held micro terminal is not used for more than
10 minutes, the system automatically switches back to the
main menu. This reduces the risk of unintentional entry of
settings.
The possible settings and displays are shown in the table
on the next page. Scrolling up and down in the menu
is done by turning the adjusting knob on the hand-held
micro terminal, and selections are entered by pressing on
the adjusting knob. Modification of the selected values
is done by turning the adjustment knob. Select "Exit" to
leave the menu.
Standard Modbus address is Address = 54.
Standard baudrate is set to 38.4 Kbit/s.
The Modbus address and other motor parameters can be
changed in the hand-held micro terminal.
The standard Modbus address and baudrate can be
changed with the hand-held micro terminal in the follow-
ing way:
With the function selector switch (See illustration) set to
”0”, set the parameters to the required values with the
hand-held micro terminal. When the new values have
been set, set the function selector switch to position "1".
This activates the user-preset parameters.
The hand-held micro terminal will not work if the
baudrate is changed from the standard setting of 38.4
kBit/s and if the hand-held micro terminal is disconnected
from contact "C".
If the standard baudrate is changed from 38.4 Kbit/s and
the hand-held micro terminal is disconnected from its con-
nection, it will only be possible to restart communication
with the hand-held micro terminal if the function selector
switch is set to position "0". The baudrate will then be
set to 38.4 Kbit/s. If the function selector switch is subse-
quently set to position "1", the user-preset parameters
will be activated again.
