3.5. Function Assignment to Control Inputs/Outputs
You may change the function assignment to the ports of CN6 (Interface connector) and CN2
(Control I/O connector). (Excludes certain port.)
◊ Counter change to an expanded function
◊ Transfer a previously assigned function to other port.
◊ Mask the function of an unused port.
This makes you to be able to assign a required fucntion with the desired arrangement.
◊ In addition to the function assignment, the input signals from the CN2 connector can change the
contacts of every port, and can insert filters.
The PI0 and PO0 are dedicated ports for the signals fundamental to the safety function. There are
following restrictions respectively.
◊ You cannot change the function setting of Input EMST (Emaergency stop) of the Port PI0
(RYm0).
◊ The Output NRM (Normal) is the only function that can replace the setting of the Output DRDY
“Driver Unit ready” of the Port PO0 (RXm0).
The input signals can be gotton from either one of the CN6 or the CN2 connector in accordance
with the operation mode (Fieldbus mode or Maintenance mode).
However, there are following exceptions.
◊ The port assigned to the Input EMST (Emergency stop) regards an input of both CN2 and CN6
connectors as “Emergency stop”. This means that the system gets in the emergency stop state by
either one of them.
◊ The port assigned to Input OTP/OTM (Over travel limit switch position) or Input HLS (Home
position limit switch) function accepts only the input from the CN2 connector regardless the
operation mode.
