Bit Usage
DO0 Motor control bit 0
DO1 Motor control bit 1
DO2 Motor control bit 2
DO3 Motor contr0l bit 3
(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.
PKW mechanism for parameter transfer
A single message type is used which contains the parameter number to be read or written.
The structure of the message is based on the PKW protocol as used in USS
communications.
Structure
The basic structure of the PKW is shown in the figure below. it consists of two words of
metadata followed by parameter data s required. As required by AS-i, all transfers are
initiated by the AS-i master and where appropriate, responded to by the slave.
