Pin Numbers of PLG Output Signals (Tamagawa Seiki, TS1508N207)
Pin Number Output Signal Pin Number Output Signal
C A-phase signal H +5V power supply
R A-phase inverse signal K Power supply common
A B-phase signal E Case earth
N B-phase inverse signal
B C(Z)-phase signal
P C(Z)-phase inverse

Note: When PLG feedback control and orientation control are used together, the PLG is shared between these
controls.
Use a PLG which has a pulse count of 1000 to 4096ppr (pulses per revolution).
