(3) Confirming the default parameters
Set the orientation start(ORC) and orie ntation complete(ORCF) for the general-purpose
input/output. If there is a gear, set the gear selection 1,2(GR1,G R2) for the gene ral-purpose input.
And, set the default parameters for each detecto r used in orientation control.
(a) Motor PLG
Motor PLG orientation is possible only when the spindle and motor are coupled, or when they
are coupled 1:1 with gears (timing belt). The SP025 (GRA1) to SP032 (GRB4) parameters can
be set only to 1. The PLG with Z-phase must be mounted on the motor to be used.
(b) 1024p/rev encoder
An accurate gear ratio (pulley ratio) is required from
the motor shaft to the encoder axis.
Make sure that the correct number of gear teeth is
set in SP025 (GRA1) to SP032 (GRB4).
SP025 to SP028=A × C × E
SP029 to SP032=B × D × F
