13.4.5 Forced stop function
DANGER
When the forced stop is required to be wired, ensure to wire it in the negative logic using b-
contact.
Provided safety circuit outside the Simple Motion module so that the entire system will operate
safety even when the "[Pr.82] Forced stop valid/invalid selection" is set "1: Invalid". Be sure to
use the forced stop signal (EMI) of the servo amplifier.
By the Simple Motion module external input connection connector is connected forced
stop input, this function is available for all axes of servo amplifier. (The initial value is
"0: Valid".)
The forced stop input valid/invalid is selected by "[Pr.82] Forced stop valid/invalid
selection".
The details shown below explain about the "forced stop function".

[1] Control details
The servo warning "Controller forced stop warning" (warning No.: E7) will occur if
turned on the forced stop input signal when the "[Pr.82] Forced stop valid/invalid
selection" is set "0: Valid". And then it is available for all axes of servo amplifier.
The outline of the forced stop process is shown below.
