* Connect the common voltage line of the source driver to +24 V on the
Classification : 24–V input, tied to common 24 V
Function : TDI01 to TDI08 can be used as eight
general–purpose DI signals.
Classification : 24–V sink output, 24–V/220–mA load
Function : TDO01 to TDO06 can be used as six
general–purpose DO signals.
Classification : 24–V source output, 24–V/200–mA load
Function : A source driver is used to output 24 V to a signal pin
when the corresponding signal is set to 1 by the PMC.
Classification : 24–V input for emergency stop
Function : The contact signal from the emergency stop button
on the operator’s panel is connected in series with
*LOT within the loader I/O board. This signal drives
the externally mounted emergency stop control relay.
See also Section 3.7.7, ”Connecting an Emergency
Stop System.” Connect contact B of the emergency
stop button on the loader operator’s panel to
*ESPTP1 and *ESPTP2.
If the cable is disconnected from this connector, the
loader immediately performs an emergency stop.
When this connector is not used, install a dummy
connector, instead of the cable, to enable signal
