Emergency stop function (Pr.1103)
When a fault occurs in the superordinate controller, the motor can be decelerated by the signal input via an external
terminal.

1103 Deceleration time at
F040 emergency stop
• The motor will decelerate to stop according to the settings of Pr.1103 Deceleration time at emergency stop
and Pr.815 Torque limit level 2 when the Emergency stop (X92) signal is turned OFF (when the contact is
opened).
• 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.

Set the output current detection time. Enter the time from
when the output current reaches the set current or higher
to when the Output current detection (Y12) signal is output.
Set the time from when the output current drops to the
Pr.152 setting or lower to when the Zero current detection
(Y13) signal is output.
Set the torque limit level at a deceleration by turning ON
the X92 signal.
The torque limit set to Pr.22 is valid.
Set the motor deceleration time at a deceleration by
turning ON the X92 signal.
