Speed Reference Selection
Parameter b1-01 determines the source of the speed reference.

<1> If source of the speed reference is assigned to the control terminals (b1-01 = 1), then d1-18 will automatically be set to 0 (so that the drive uses
multi-speed references d1-01 to d1-08) by the drive's internal processing.
<2> If the speed reference selection in d1-18 is set so that either the high speed reference has priority (d1-18 = 1), or so that the leveling speed has
priority (d1-18 = 2), then the drive will look to the multi-function input terminals for the speed reference.

Up / Down Command Source Selection
The input source for the Up and Down signal can be selected in parameter b1-02.

Travel Start and Stop
Travel Start
To start the elevator in the up or down direction, the following conditions must be fulfilled:
• A speed reference greater than zero must be selected.
• The Safe Disable signals at terminals H1 and H2 must both be closed.
• An Up or Down Signal must be set at the source specified in b1-02.
Travel Stop
The drive stops under the following conditions:
• The Up or Down command is cleared.
• d1-18 is set to 1 or 2 and the Up/Down or Leveling Speed signal (H1- = 53) is cleared.
• d1-18 is set to 3 and all speed inputs are cleared.
• A fault occurs. The stopping method depends on the fault occurred and certain parameter settings.
• The Safe Disable inputs are opened or a Base Block signal is input. In this case the brake is applied immediately and
the drive output shuts off.

Set the speed references in the d1- parameters and use digital inputs to switch over
between different reference values.
Apply the speed reference signal to terminal A1 or A2.
