LI - Input Parameters
ETS - Emergency Terminal Slowdown
The Emergency Terminal Slowdown (ETS) can be used as an alternate
slowdown prole, or quick stop.
The ETS input is an active low input controlled by the controller. ‘ETS Input
Failure fault will occur if the ETS input is not detected (high) at the beginning
of a run.
When the ETS input is dropped (pulse or constant), the drive will begin to
compare the encoder speed against the LX17 ETS Speed threshold.
If the encoder speed becomes GREATER than the corresponding LX17
ETS Speed threshold, then the drive will decelerate to the LS01 Leveling
Speed using the dedicated LS48-49 ESD/ETS deceleration and jerk rates.
The ETS 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 LS01
Leveling Speed until the hardware direction input is dropped. If the ETS
is triggered and the external (analog or serial) speed command goes
below the LS01 Leveling Speed, the drive will continue to run the motor
at the LS01 leveling speed. When the direction is dropped, the drive will
decelerate to zero speed.
If the encoder speed remains LESS than the corresponding LX17 ETS
Speed threshold, the drive will continue as normal.
If an ETS slowdown has been initiated, the maximum speed will be limited to
the LS01 Leveling 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.
