Hoistway Parameter Set-up
4) Enter / verify the hoistway parameters:
CONTRACT CAR SPD (A1) parameter should be the elevator contract speed in m/s.
CONTRACT MTR SPD (A1) parameter should be set to a RPM that will make the elevator
travel at desired car speed (measured with hand tachometer)
NOTE:
The above two parameters are utilized by the drive for many purposes regarding the control of
the lift, therefore it’s important these are set correctly.

CONTRACT CAR SPD
Elevator contract speed
400.0
fpm
Adjust to speed the installation is rated
to run at.
0.0
m/s
CONTRACT MTR SPD
Motor speed at elevator contract speed

rpm
Adjust this value to ensure the actual
running speed of the car matches the
parameter above - If the car is traveling
too fast then reduce this value, if too
slow then increase it.

PPR
Obtain the Encoder PPR from the
encoder nameplate and enter in this
parameter.
MTR TORQUE LIMIT
Motoring Torque Limit. Units in percent of
