Connecting-up
X420 - Pulse encoder
simulation
4-4
At connection X420 you can pick up the signals of the pulse encoder
simulation generated on the optional board.
A zero pulse which does not exist (if a multiturn encoder is connected) is
simulated by the board.
The simulation signals are available as differential signals according to
standard RS 422.
