Success.

My suspicions were correct - there are undocumented parameters to set in the drive before the digital outputs can be activated.

Stepperonline advised the following:
Warning: Spoiler!


Parameters C04.59 and C04.5A are not in the manual.  They are, however, visible in the tuning software (see attached screenshot).

I've attached a bare-bones xml file which will create HAL pins for all five digital inputs, and two of the three digital outputs.  The last output - DO3 - is reserved for the motor brake and commented out.

As usual, thanks to everyone for helping out.

Great you worked it out. But normally, there will also be settings to tell the type of input. eg, GPIO, Max Limit, Min Limit, Estop (disable drive),
Did you work that out too? eg If you want to use as GPIO, you need to set the type to be GPIO for a specific pin for internnalhoming, you need to set homing.

Yes, I worked that out, too.  I'd already set the DIO appropriately before starting this thread.

Unlike the missing output information, the manual is explicit on DIO function configuration:
  • Via parameters:
    • DI - C04.00-C04.12
    • DO - C04.30-C04.35
  • Via Ethercat:
    • 2004, sub-index 01 through 36
As I stated in my first post, this was a only basic bench test to explore the drive's IO with some buttons and LED's.
