Introduction to I/O Control

The Screwdriver can be controlled and monitored by standard digital I/O. The Spin Bridge has 8 digital inputs and 8 digital outputs. The digital inputs can be used to control the screwdriver. The digital outputs can be used to monitor the screwdriver.

The basic steps to I/O Control are as follows:

• Enable I/O control by setting DI8 high.

• The system is ready when the DO1 is high.

• Select the desired action, by setting the DI 1-5 to the desired value.

• Start the action by setting DI6 high.

• If the action is to start a screw program, the screwdriver will start and the DO4 (OK), DO5 (Not OK) or DO6 (Fault) will go high when the screwdriver is done.

Inputs 1 to 5 are mapped to actions on the Spin Dashboard. The rest of the I/O is fixed:

Digital inputs

Input	Function
DI1–DI5	Configurable
DI6	Start action
DI7	External event
DI8	Enable and disable I/O control

Digital outputs

Output	Function
DO1	Bridge ready
DO2	Freedrive button
DO3	Action button
DO4	Evaluation OK
DO5	Evaluation Not OK
DO6	Evaluation Fault
DO7–DO8	Unused

The subsequent sections will cover the details of how to control the screwdriver by running configurable actions mapped to the digital inputs.
