LX17 ETS Speed
Emergency Terminal Slowdown (ETS) Speed corresponding to input programmed as
ETS Speed (29).
This parameter sets the speed limit the elevator must be under once the ETS switch is
crossed. The ETS sensors, normally closed type, must be routed to an input on the drive.
If the input turns off and the car speed is still above this value, the drive will automatically
trigger an emergency terminal slowdown using LS48-49 ESD/ETS Deceleration and Jerk
rates.  Refer to the ETS input function under parameter LI04 Input 1 Function.

LX18 Braking Resistance
The braking resistor value can be set which allows the drive to calculate the total energy
dissipated by the resistor. A running total of the dissipated energy is measured in kWHrs
and is stored in drive parameter DG42 Regenerative Energy, or Diagnostic Screen #8
Braking Energy.
This provides the equipment owner an estimation of potential energy savings from line
regeneration.

If the motor moves by more than the value set in LX25 after a normal high
speed run (not inspection operation), the Unintended Movement event will
occur.
