(1) The AS-i specification mandates the simultaneous use of 'Motor Left' and 'Motor Right' as fault acknowledge, particu-
larly if there is no spare input available for this function.
(2) If no fault is active then simultaneous operation of 'Motor Left' and 'Motor Right' constitutes a process image error. In
this state both the inverter motor outputs and the motor holding brake outputs are inactive, causing the motor to coast to a
halt and engaging the motor holding brake in exactly the same way as an OFF2 command. This state is maintained until
both 'Motor Left' and 'Motor Right' are deactivated at the same time.
