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.

Forced stop EM1 CN1-8 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. DI-1
Proximity dog DOG CN1-25 When DOG is turned OFF, the proximity dog is detected. The polarity
of dog detection can be changed using parameter No. PE03.

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.
