2. Specifications
2 - 15
(c) Orientation function (spindle set position stop function) (option)
1) 1 point orientation
When the orientation signal is input, the spindle is stopped at the set position determined
by an internal parameter.
When using external 1024p/rev
encoder or motor PLG
When using magnetic sensor
Available stop position
setting range
360°
±5°
based on center of magnet and sensor
Stop position resolution 360°/4096 divisions Approx. 5°/512 divisions
Repeated stop position
accuracy
±
0.1° ±0.1°
(Note 1)
The repeated stop accuracy or resolution in the above table may not satisfy the accuracy according to
backlash or friction torque, etc of machine.
(Note 2)
When using magnetic sensor, the position accuracy or stop position range differs from the above table
according to the installation radius.
(Note 3)
Motor PLG orientation is possible only when the spindle and motor are coupled, when they are coupled at 1:1
with gears, or when they are coupled at 1:1 (pulley ratio) with a timing belt.
The Z phase signal must be provided to the motor speed detector.
2) Orientation
The spindle stop position in the orientation command input is changed arbitrarily using
external 12 bits stop position command.
When using external 1024p/rev encoder or motor PLG
Available stop position
setting range
360°(arbitrary according to external stop command)
Stop position resolution 360°/4096 divisions
Repeated stop position
accuracy
±
0.1°
(Note 1)
The repeated stop accuracy or resolution in the above table may not satisfy the accuracy according to
backlash or friction torque, etc of machine.
(Note 2)
Motor PLG orientation is possible only when the spindle and motor are coupled, when they are coupled at 1:1
with gears, or when they are coupled at 1:1 (pulley ratio) with a timing belt.
The Z phase signal must be provided to the motor speed detector.
3) Multi-point indexing orientation
By setting the orient command and indexing forward run/reverse run to the
general-purpose input, the stop position is changed arbitrarily without one rotation of the
spindle.
When using external 1024p/rev encoder or motor PLG
Available stop position
setting range
360°(arbitrary according to external stop command)
Stop position resolution 360°/4096 divisions
Repeated stop position
accuracy
±
0.1°
(Note 1)
The repeated stop accuracy or resolution in the above table may not satisfy the accuracy according to
backlash or friction torque, etc of machine.

Motor PLG orientation is possible only when the spindle and motor are coupled, when they are coupled at 1:1
with gears, or when they are coupled at 1:1 (pulley ratio) with a timing belt.
