Example:

The application requires the use of Encoder 4 on board a Turbo PMAC2 as a triggered time base master

for coordinate system 1. It is to be triggered by the rising edge of its index channel. The real-time input

frequency is selected as 256 counts/msec. The conversion table starts with 8 single-line entries in I8000 –

I8007.

Setup On-line Command

I8008=$AF8018 ; Triggered time base from PMAC2 channel 4

I8009=64 ; TBSF=16384/256

I7042=1 ; Servo IC 0 Channel 4 trigger on rising index

I5193=@I8009 ; C.S.1 use I8009 result for time base

M403->X:$07801B,0,24,S ; Channels’ captured position register

Motion Program Segment

DWELL 0 ; Stop any lookahead

I8008=$9F8018 ; Freeze the time base

P403=M403 ; Dummy read to ensure capture logic reset

X10 ; Calculate first move

PLC Program Segment

IF (I8008=$9F8018) ; If frozen

I8008=$BF8018 ; Then arm
