4.2.3 Electronic gear for input commands
Through the electronic gear user can define that one input command pulse will cause an
adjustable movement of mechanical device. Therefore, the host controller does not have to
consider that the gear ratio in the mechanical system and the encoder line number of the
servomotor .The electronic gear variable is illustrated in the following table.
