Drive Type (J01) shows the core product type as given in the table below. The drive could be the basic product or a derivative of the basic product
defined by Drive Derivative (J96).
This indicates the elevator software state number for the elevator state machine.

J03 Elevator software state Description
0 Idle (wait for travel request):
To exit the idle state the following conditions need to be met:
• Drive OK parameter Drive OK (L05) = On (1)
• A speed reference has been selected and a direction input has been received (if dual direction inputs are used) OR
• A speed reference has been selected if single direction input is used. OR
• If the enable and Fast disable (if used) are received (speed and direction not required)
Provided brake contact and Motor Contactor Monitoring Enable (B29) = On (1), and none of the above conditions are true, check the state of Motor
Contactor Monitoring Input (B30) and the brake contact and generate trips if they are in the incorrect state. The motor contactors should be open,
but if it is closed generate Trip 71 (Mot con Closd) indicating an incorrect state. The brake contact should be open, but if it is closed and Brake
Contact Monitoring Select (D11) > 0, generate Trip 73 (Brk con 1 closd) and Trip 75 (Brk con 2 closd) indicating an incorrect state.
Force all contactor and control outputs to Off (0) while a travel is not requested i.e. brake and motor contactor.
On exit from state 0:
• Sample the autotune selection parameter Motor Autotune (B11).
Exit to state 1:
• If the speed / direction signal starts the travel.
On exit to state 1:
• Sample the start time for the Safe Torque Off and Fast disable inputs (if used). Used to call Trip 65 (Fast disable err) and Trip 66 (STO ctrl err)
(time from the command to close the motor contactors to close to receive the Safe Torque Off OR Safe Torque Off and Fast disable (if used).
• Close the motor contactors via Motor Contactor Control Output (B31).
Exit to state 2:
• If Safe Torque Off (STO) and Fast disable starts the travel.
