Application Notes Addendum to Acc-29 Starting with PMAC firmware version V1.14, it is necessary to use motor setup variable Ix10 to get the absolute power-on position from the MLDT sensor. Ix10 specifies the register to read for absolute power-on position, and how to read the data in that register. If Ix10 is set to 0, PMAC will set the power-on position for that motor to 0, even if an absolute position device is used for the motor. Ix10 must use the raw data register for the sensor, not the processed data register in the conversion data. For the Acc-29 MLDT interface, the values of Ix10 to use are: MLDT1 Timer 9 ( Y: $ C020 ) Ix10 = $ 18C020MLDT2 Timer 10 (Y:$C024) Ix10 = $18C024 MLDT3 Timer 11 (Y:$C028) Ix10 = $18C028 MLDT4 Timer 12 ( Y:$C02C ) Ix10 = $18C02CMLDT5 Timer 13 (Y:$C030) Ix10 = $18C030 MLDT6 Timer 14 (Y:$C034) Ix10 = $18C034 MLDT7 Timer 15 (Y:$C038) Ix10 = $18C038 MLDT8 Timer 16 (Y:$C03C) Ix10 = $18C03C The 18 in the first two hexadecimal digits specify that this is a 24-bit register that is being read (18 hex =24 dec). The last four hex digits specify the Y address of the register to be read. > MLDT Sensor 1 size="-1">
