Parameters (F) Setting of acceleration/deceleration time and acceleration/deceleration pattern
FR-A800 5 - 247
Emergency stop function (Pr. 1103)
●
When the emergency stop (X92) signal is ON, the deceleration stop is performed according to the
settings in the Pr. 1103 "Deceleration time at emergency stop" and Pr. 815 "Torque limit level 2".
●
To input the X92 signal, set "92" in any of Pr. 178 to Pr. 189 (input terminal function selection) to
assign the function to a terminal.
●
The X92 signal is a normally closed input (NC contact input).
●
[PS] is displayed on the operation panel during activation of the emergency stop function.

NOTE The X92 signals can be assigned to an input terminal by setting Pr. 178 to Pr. 189 (input terminal
function selection). Changing the terminal assignment may affect other functions. Set parameters
after confirming the function of each terminal.
