12.1. Electronic Gear
The electronic gear function enables the servomotor travel distance
per input reference pulse to be set to any value. It allows the
pulses generated by the host controller to be used for control
without having to consider the equipment gear ratio or the number
of encoder pulses.
This is done by setting the Electronic Gear Ratio, which is the ratio
of the number of pulses that are input to the FSP Amplifier control
algorithm to the number of reference input pulses received from
the host controller. The user position units can then be set in terms
of the pulses that are input to the FSP Amplifier control algorithm.

12.1.1. Electronic Gear Parameters
The electronic gear ratio, B/A, is ratio of the number of pulses
received by the FSP Amplifier from the master or host, to the
number of pulses seen by the motor.
♦ Pn200 specifies the form of the reference input pulse.
♦ Pn202 is the numerator of the electronic gain ratio, B.
♦ Pn203 is the denominator of the electronic gain ratio, A.
It is recommended that the master used should have a higher
resolution than the slave.
