Accessory 24E2A
Ixx05: Motor xx Master Position Address
Usually, the Ixx03, Ixx04, and Ixx05 variables contain the address of a processed position value in the
encoder conversion table, even when the raw data comes from the Acc-24E2. The first line of the
encoder conversion table is at address $003501; the last line is at address $0035C0.
Ixx10: Motor xx Power-On Position Address
Ixx10 tells the Turbo PMAC where to read absolute power-on position, if any. Typically, the only times
Ixx10 will contain the address of an Acc-24E2 register is if the position is obtained from an A/D
converter on an Acc-28B connected through the Acc-24E2, or if it is obtained from an MLDT (e.g.
Temposonics
TM
) sensor excited directly from an Acc-24E2.
The following table shows the possible values of Ixx10 for MLDT timer registers:

Ixx24: Motor xx Flag Mode
Ixx24 defines how to read and use the flags for Motor xx that are in the register specified by Ixx25.
Ixx24 is a set of independent control bits. There are two bits that must be set correctly to use a flag set on
an Acc-24E2.
Bit 0 of Ixx24 must be set to 1 to tell the Turbo PMAC that this flag set is in a Type 1 PMAC2-style
Servo IC. Bit 18 of Ixx24 must be set to 0 to tell the Turbo PMAC that this flag set is not transmitted
over a MACRO ring. Other bits of Ixx24 may be set as desired for a particular application.
Ixx25: Motor xx Flag Address
Ixx25 tells Turbo PMAC where to access its flag data for Motor xx. If Acc-24E2 is interfaced to the
flags, Ixx25 must contain the address of the flag register in Acc-24E2.
The following table shows the address of the flag register for each channel of each Acc-24E2.
