13. POSITIONING MODE
13.2.3 Signal explanations
For the I/O interfaces (symbols in I/O division column in the table), refer to section 3.8.2. In the positioning
mode field of the table
CP : Point table method CL: Program method
: Denotes that the signal may be used in the initial setting status.
: Denotes that the signal may be used by setting parameter No. PD02, PD04, PD06, PD08, PD10, PD12,
and PD14 to PD18.
The pin No.s in the connector pin No. column are those in the initial status.

When EMG is turned off (contact between commons is opened), the
servo amplifier falls in a forced stop state in which the base circuit is
shut off, and the dynamic brake activates.
When EM1 is turned on (contact between commons is shorted) in the
forced stop state, the state can be reset.
CN1-25
When DOG is turned OFF, the proximity dog is detected. The polarity
of dog detection can be changed using parameter No. PE03.
Parameter No. PE03
0
To start operation, turn LSP/LSN on. Turn it off to bring the motor to a
sudden stop and make it servo-locked.

A stopping method can be changed by parameter No. PD20.
Set parameter No. PD01 as indicated below to switch on the signals
(keep terminals shorted) automatically in the servo amplifier.
Parameter No. PD01
If LSP and LSN are not assigned to the external input signals, they
turn ON automatically regardless of the value set in parameter No.
PD01.
When LSP or LSN turns OFF, an external stroke limit warning (99. )
occurs, and warning (WNG) turns OFF. However, when using WNG,
set parameter No. PD15 to PD18 to make it usable.
