MLDT Feedback for UMAC-Turbo & UMAC-MACRO

MS{anynode}, MI16x (xth Motor Node MLDT Frequency Control)
This variable establishes the frequency of the excitation pulse sent to the MLDT. Its value is written
automatically to the full 24-bit C sub-channel command register for the channel assigned to this node, so
the PFM circuit will create a pulse train at this frequency.
To compute the output frequency as a function of MI16x, the following formula can be used:

Power-On Feedback Address for PMAC2 Ultralite
Both the Ultralite and the Turbo Ultralite can obtain absolute position at power up or upon request (#n$*).
The Ultralite must have Ix10 setup and the Turbo Ultralite needs both Ixx10 and Ixx95 setup to enable
this power on position function. For power on position reads as specified in this document, MACRO
firmware version 1.114 or newer is needed, the Turbo Ultralite firmware must be 1.936 or newer, and the
standard Ultralite must have firmware version 1.16H or newer.
Ix10 permits an automatic read of an absolute position sensor at power-on/reset. If Ix10 is set to 0, the
power-on/reset position for the motor will be considered to be 0, regardless of the type of sensor used.
There are specific settings of PMAC’s/PMAC2’s Ix10 for each type of MACRO interface. If a Turbo
Ultralite is used, Ixx95 must also be set appropriately. The Compact MACRO Station has a
corresponding variable I11x for each node that must be set.
