LI - Input Parameters
NTS - Normal Terminal Slowdown
The Normal Terminal Slowdown (NTS) can be used as an alternate slowdown
prole, or quick stop.
The NTS input is an active low input controlled by the controller.
When the NTS input is dropped (pulse or constant), the drive will begin to
compare the encoder speed against the corresponding NTSD threshold and
direction (TS03-08).
IF the encoder speed becomes GREATER than the corresponding NTSD
speed threshold (TS03-08), then the drive will decelerate to the TS02 NTSD
Target Speed using the LS33-35 One Floor prole deceleration and jerk
rates. The NTS prole generated by the drive will bypass any controller-
generated serial or analog prole. The drive will then continue to run at the
TS02 NTSD Target Speed until the hardware direction input is dropped. If
the external (analog or serial) speed command is less than the TS02 NTSD
Target Speed, the drive will follow the external command speed. When the
direction is dropped, the drive will decelerate to zero speed.
ELSE, IF the encoder speed remains LESS than the corresponding NTSD
speed threshold (TS03-08), the drive will continue as normal.
If an NTS slowdown is initiated, then the maximum speed will be limited to the
TS02 NTSD Target Speed until the end of the run when the enable command
is dropped.
The nal stopping jerk when the direction is dropped at the end of the run will
use the LS43-45 Emergency prole deceleration and jerk rates.
Refer to Section 6.17 Terminal Slowdown parameter group for additional
information.
