3. Operation
3.1. Operation Mode and Input/Output
There are two ways to input signals to the Driver Unit CN2: control Input/Output connector and
remote input by the CN6: interface connector. There are two operation modes to receive those
inputs exclusively.
◊
Fieldbus mode: The prompt of the Handy Terminal is “
#
”.
◊
Maintenance mode: The prompt of the Handy Terminal is “
:
”.
The operation mode and format of Inpt/Output are shown in the Table 3-1 “Operation mode and
composition of Input/Output” (The function assignment is the shipping set).
◊
The operative Inputs/Outputs of each operation mode are shown in the bold line boxes below.

In case of the fieldbus mode, take the input signals from the CN6 connector. For the maintenance
mode, take them through the CN2 connector. However, there are following two exceptions.
◊
The port assigned to the Input EMST (Emergency stop) regards the Input of both CN2 and CN6
connectors as the “Emergency stop” signal. This means that the system gets in the emergency
stop state by either one of the inputs.
