TS02 NTSD Target Speed
The speed, when NTSD is active, to which the drive will decelerate and maintain as the
maximum speed until the end of the run (STO inputs dropped). With analog and serial
speed control, a speed command below the NTSD target speed is allowed. When the
direction command is dropped, the LS43-45 emergency profile deceleration and jerk
rates will be used to decelerate to zero speed.

8.16.3 NTSD Thresholds and Direction
The speed threshold which the motor encoder speed is compared against when the
corresponding NTSD input drops (activates) in the indicated direction. If the motor speed
is above this threshold, the drive will initiate an NTSD slowdown using the LS33-35 One
Floor profile deceleration and jerk rates.
