2.9 Using external SSI encoder
I/O Setup
Because of the strict timing in the motor it is not possible to read the encoder value when
motor has started. This is due to strict timing control in the motor.
As a new feature the MAC40-141 firmware now supports setting up IO1 and IO2 as user
controllable. IO1 and IO2 is settable from these controls.
When all values has been setup, remember to save in flash and/or into a .mac file before
removing power from the motor.
If an encoder is available on the motor, the actual position value is read as soon as the
motor start-up after a reset.
