If a reduction between motor and loads exists, to multiply the factor:
a turn of motor shaft
mechanism turns
.
The following example explains the method for setting the electronic gear ratio.
Load distance per revolution is 1mm
,
the resolution of motor encoder is 2500ppr
,
the gear ratio of
load mechanism to motor shaft is 1, if the demand distance is 5µm
,
the calculation is listed below.
2500 4
1
10000
Electronic gear ratio=
1mm / 5 m
1
200
From above, it could be known that by setting the electronic gear numerator as 4194304 and set
the electronic gear denominator as 200, and then the ball screw rod would be shift a 5-µm distance
after a position pulse command.
