(8) Repeat Encoder (TTL line-driver) (ADL510-530-550)
ADL500 have an incremental encoder output with TTL Line Driver levels to be used to repeat the servomotor feedback
device.
This function is performed via HW and an encoder output can be repeated with a programmable divider.
The encoder output signals are available on the XER connector:
