6.13 External Stop Function

6.13.1 EXSTOP (External Stop Input) Signal

6.13

External Stop Function

The external stop function forces the Servomotor to stop when an external switch that is con-
nected to the SERVOPACK operates. The EXSTOP (External Stop Input) signal is used for the
external stop function. If the switch operates, a hard stop is performed for the motor and the
servo is turned OFF.
Note: The external stop function is not designed to comply with any safety standard. In this respect, it is different
from the hard wire base block (HWBB).
