How many pulses per revolution of the 500-line photoelectric encoder？

The so-called number of lines is the number of pulses output per revolution. They can be said to be different names for the same thing. For example, a 500-line encoder can output 500 A (or B) pulses per revolution. Of course, the QEP module of DSP supports the processing of the original AB signal, which can multiply these 500 pulses to 4 times, that is, 2000 count pulses. Photoelectric encoder
