The function varies depending on the operation mode.
The polarity for SIG can be changed with [Pr. PT29].
1. Homing mode (hm)
SIG can be used as an input device of external limit. This operation
mode is enabled when the homing type of the torque limit changing dog
type is selected.
2. Jog mode (jg)
You can use this as an input device for specifying a rotation direction of
the servo motor. The rotation direction varies depending on the setting
of [Pr. PA14 Rotation direction selection]. (Refer to table 2.1.)
3. Indexer mode (idx) (rotation direction specifying indexer)
You can use this as an input device for specifying a rotation direction of
the servo motor. The rotation direction varies depending on the setting
of [Pr. PA14 Rotation direction selection]. (Refer to table 2.1.)
4. Indexer mode (idx) (shortest rotating indexer)
You can use SIG as an input device for selecting a speed of the servo
motor.

The current position latch function by sensor input can be used. For the
current position latch function, refer to section 11.1.1. For the interrupt
positioning function, refer to section 11.1.2.
Turning CDP on switches the values of [Pr. PB29] to [Pr. PB36] and [Pr.
PB56] to [Pr. PB60] as the load to motor inertia ratio and gain values.
