The diagram above and corresponding sequence (1-5) descriptions below show an
example of a normal run (A) and a run in which the NTS is initiated (B).
1. Normal slowdown initiated.
A. Motor tracks command speed.
B. Motor speed deviates from command speed.
2. NTS input dropped. Motor encoder speed compared with NTSD speed threshold.
A. Motor speed less than or equal to NTSD speed threshold ->
1. Normal deceleration.
B. Motor speed greater than NTSD speed threshold ->
1. Initiate NTSD Slowdown using LS33-35 One Floor profile rates.
2. NTSD output turns on.
3. Maximum speed limited to TS02 NTSD Target Speed until end of run.
3. NTS slowdown reaches NTSD Target Speed.
A. Normal slowdown active.
B. External speed command (analog or serial) below NTSD Target Speed
allowed; NTSD Output turns off if external (analog or serial) speed command
is less than NTSD Target Speed.
4. Direction dropped.
A. Decelerate to zero speed.
B. Decelerate to zero speed.
5. STO Inputs dropped.
A. End of run.
B. End of run.
