Sudden stop selection (Ver.1.20 or later)

This function suddenly stops the work piece when the STOP command/forward rotation limit switch 2 (FLS),
reverse rotation limit switch 2 (RLS)/forward rotation limit switch 1 (LSF) or reverse rotation limit switch 1
(LSR)/software limit turns ON during positioning operation.
→ For handling of the forward rotation limit and reverse rotation limit, refer to Section 7.3
1. For specifying the sudden stop operation performed when the STOP command or rotation
limit switch turns ON, set the following positioning parameters.

2. Sudden stop operation
1) The work piece suddenly stops after the sudden stop deceleration time (Sudden stop interpolation time
constant) when the STOP command or limit switch turns ON during operation. However, the work piece
stops after the normal deceleration time when the sudden stop deceleration time (Sudden stop
interpolation time constant) is longer than the normal deceleration time (interpolation time constant).
