Error solution
Steps:
1.
check the encoder socket and the main control encoder connect well or not
2.
check the impedance of pin 1 /
p
in3 to pin2 of U1 of encoder board: around 0.7M, power supply with 80V isolation
transformer, standby voltage: 1.2V. Test the both ends voltage D1: 0.5V
3.
check the impedance of
p
in 3 to pin 2 of Q1 of encoder board: around 0.8M, power supply with 80V isolation transformer,
standby voltage: 5.1V. the impedance of foot 1 to
p
in 2 of Q1: around10K [note: when the encoder link to main control box,
the impedance above is different] [ the voltage of U1 responsed to raster notch is around 0V]
4.
check whether the
p
in 3/plug J1(4pins) of Q1 of encoder connect with the main control plugJ2(4pins)
