[Setting example]
Main Motor : Encoder pulse 1024 pulses
Sub Motor : Encoder pulse 3000 pulses
(Main motor rotation speed) : (sub motor rotation speed) = 2 : 1
Set the following for slave inverter in this case.
Electronic gear setting position (P019) : RET (command pulse side)
Electronic gear numerator (P020) : 3000
Electronic gear ratio denominator (P021): 1024*2=2048
