When the acceleration of the Tracking Master bit in the instruction Control
Word is cleared, it is not sensitive to the acceleration due to the master being
accelerated. The master is only sensitive to the acceleration of the slave caused by a
programmed change in the speed of two successive instructions.
Actions Taken When Stopping/Shutdown Instructions are Executed on the Slave
Axis.
All commands in the following table are for the Slave Axis system. The following
table identifies the change in state of the MDAC link between the master and
slave axis as each instruction in column 1 is executed on the slave axis.
