• If rapid acceleration/deceleration is set for normal operation and E.OA (Acceleration error) is activated, set Pr.375 = "9999"
to disable the acceleration rate error detection.

 Emergency stop function (Pr.1103)
• When the Emergency stop (X92) signal is OFF (when the contact is opened), 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 parameter from 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) when it is input via an external input terminal, and a normally
open input (NO contact input) when it is input via communication.
• "PS" is displayed on the operation panel during activation of the emergency stop function.
• The following diagram shows the operation when the signal is input via an external input terminal.

*1 ON/OFF indicates the input status of the physical terminal.
NOTE
• The X92 signal 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.
