Description
reduction ratio between the encoder mounting
shaft and pulley shaft. If the encoder is mounted
on the pulley, set P93.09=1.
For example, for gear speed reduction,
Mechanical transmission ratio = (Number of
teeth in gear 2)/( Number of teeth in gear 1)
Gear 2

Note: The suspension ratio is related to the
pulley through which the steel rope goes.
Rope length to compensate the distance from
the center of gravity of the weight to the hook.

1. To measure heights correctly in closed-loop
mode, the actual running distance of the motor
is calculated by using the encoder pulse count.
