2.5.4 J4 and J5 Discrete Input/Output Connection
Introduction
Connectors J4 and J5 contain all the programmable inputs and
outputs for the 5645:
The 16 inputs are for external discrete switch-type devices.
Inputs are used with functions and variables from the
program. Six of the 16 inputs can be used for dedicated
functions. The 5645 discrete input circuit is shown at the
end of this section, in addition to several drive circuits.
The 12 outputs are programmable for sending out signals.
Output 12 can be dedicated to indicate when the motor is
moving. These outputs are driven by open collector NPN
transistors and can sink up to 50 mA. Several load
configurations are shown at the end of this section.
For information on using the inputs and outputs, refer to the
specific variable in the 5645 Programming Manual.

Explanation
OUT 1
J4-11
Outputs are controlled by the user’s program. To turn
On an output, set the variable OUTn to 0; to turn it Off,
set to 1. For example, if you set OUT6 to 0 in your
program, output 6 is active (low), displayed as OUT6 =
0.
If you program the predefined variable PREDEF.OUT
= 1, output 12 (J5-15) will be active (low) whenever
the motor is moving.
