The speed, when NTSD is active, to which the drive will decelerate and
maintain as the maximum speed until the end of the run (enable 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.
TS03 - 08: 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.
Speed threshold for NTSD 1 in the up direction.
Speed threshold for NTSD 2 in the up direction.
Speed threshold for NTSD 3 in the up direction.
Speed threshold for NTSD 1 in the down direction.
Speed threshold for NTSD 2 in the down direction.
Speed threshold for NTSD 3 in the down direction.
