4-3-3 Adjusting the orientation control
(1) Necessary input/output
1) Input:
[1] Orientation start command (ORC)
Connect to any one of the general-purpose inputs
[2] Multi-point orientation positioning data (R1 to R12)
Connect when changing to an arbitrary stop position from outside during encoder
orientation or motor PLG orientation
2) Output: Orientation complete (ORCA)
Connect to any one of the general-purpose outputs
(2) Operation sequence
Motor speed
Gear selection command
12-bit multi-point orientation command
Orientation start command
Orientation complete output
1) The 12-bit multi-point orientation command (R1 to R12) is read at the rising edge of the
orientation start command (ORC) and must be changed before turning the orientation start
command ON.
2) The gear selection com mand (GR1, GR2) will be valid at all times eve n after the orientation start
command has been turned ON. Change the gear selection command before turning the
orientation start command ON and keep it ON until the orientation start command is turned
OFF.

(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
Set the gear ratio (A:X) between the spindle and
encoder in SP096 (EGAR).

(c) Magnetic sensor
An accurate gear ratio (pulley ratio) is required from
the motor shaft to the detector rotary axis. Make sure
that the correct number of gear teeth is set in SP025
(GRA1) to SP032 (GRB1).
SP025 to SP028=A × C × E
