When Motor Contactor Monitoring Enable (B29) = On (1), then this parameter is used to monitor the state of the motor contactors. One of the elevator
drive inputs or I/O option inputs must be routed to this parameter, where the signal to activate the input comes from the motor contactors auxiliary
contacts.
When set to Off (0), the motor contactors are open, when set to On (1) the motor contactors are closed.
This input is used to generate Trip 70 (Mot con open) / Trip 71 (Mot con closd).

If the motor contactors are to be connected to the elevator drive, route this parameter to a drive digital output, which will control the motor contactors.
When set to Off (0), the motor contactors will be opened.
When set to On (1), the motor contactors will be closed.
A volatile source parameter must be used to prevent the user from saving to On (1).

This indicates the measured contactor opening time delay in ms.
This is the time from when the brake apply delay starts to when the enable is removed – Brake Control Apply Delay (D05) – Motor Torque Ramp Time
(D02). See the following diagram:
A negative time indicates that the contactor opened while current was flowing i.e. drive is disabled (via the motor contactors auxiliary contacts) during
the Brake Control Apply Delay (D05) or the Motor Torque Ramp Time (D02). Negative values can only occur in situations where the Motor contactor
