Motion 4000
Counterweight Position, 67
This is the position of the counterweight (in inches
above the bottom floor) at which the car and counterweight are adjacent to one another in the
hoistway. The value uploaded was learned in the floor level learn procedure. Check the value to
see that it equates to approximately 1/2 the total travel of the car. Press Next to move to the next
parameter.
Note
Counterweight Position: Leave at the learned value. This parameter is provided here so that,
should it be necessary, this position can be adjusted without having to re-learn floor heights.
Directional Limit Distance, 68
This is the distance in inches at which the Directional
Limit “switches” are placed beyond the terminal floor level positions. The value is entered in
inches and is computed from the position of terminal floor levels. For example, a value of 2.0
would place the switches 2” past the level at floor position for each terminal.
If the car fails to stop level at the terminal, this “switch” will prevent the car from traveling fur-
ther past the terminal landing. These “switches” must be positioned between the terminal floor
level and the mechanical Final Limit Switches. If a car reaches the Final Limit Switch, the hoist-
way safety string will open and it will be necessary to jumper out the safeties to move the car off
the limit.
Terminal Switch Options, 69 - 74
On Motion 4000, hoistway switches, with the
exception of the Final Limit Switches which are always physical switches, may be virtual (exist
only in software) or physical. Depending upon job speed, not all switch positions may be used
so there is also the option to set a switch position to “Unused.” The illustration below shows the
switches that may be used on Motion 4000 (ETS, NTS-1, NTS-2, NTS-3, NTS-4, and NTS-5).
