Example :
Channel 1 is driving a Yaskawa Incremental Encoder, with the test procedure above resulting in zone-1
definitions. Halls power-on phasing can be done in a PLC as follows:
#define Ch1IncData M7030
#define Ch1Halls M7031
Ch1IncData->Y:$78B20,0,24
Ch1Halls->*
#define Mtr1PhasePos M171 ; Suggested M-Variable definition
#define Mtr1PhaseSrchErr M148 ; Suggested M-Variable definition
Mtr1PhasePos->X:$0000B4,24,S
; #1 Present phase position (counts *Ixx70)
Mtr1PhaseSrchErr->Y:$0000C0,8,1 ; #1 Phasing error fault bit
// Zone-1 Definitions
–User Input
#define Phase30Deg 1

#define Phase210Deg 6
#define Phase270Deg 2
