Travel measurement

Functional description (only available as of FW Version AT40 V01.46 and ATD400V V01.07)
During door travel, the controller measures various motor and door mechanics data. In
addition, changes in the driving characteristics of the motor and the door can be detected
and evaluated for maintenance purposes using this data.
The following travel data are measured:
● Opening and closing times of the door
● Mechanical door energy
● Motor peak current in the slow start and end distance
● Mean power dissipation of the motor
● Current motor power
Opening and closing times of the door
● Time for the full opening operation
● Time for the full closing operation
● Opening time outside of the slow start distance
● Closing time outside of the end distance
If the measured times increase over time, this can be a sign of mechanical problems,
contamination or wear.
The times are only measured in normal operation for uninterrupted travel. No time
information is provided during initial operation or the learn run, or during reversing,
obstructions or braking due to a previous obstruction. The value zero is displayed for the
time in such cases.
The time measurement begins when the door has moved 5 mm from the opened or closed
position and ends 5 mm before the end stop.
In the slow end distance, the door interlock (slow distance) is activated, but the door is
closed. In order to distinguish between the pure travel time of the door and the time when the
door interlock is actuated, the times for the complete opening or closing operation and the
pure opening or closing travel are determined without a slow start or end distance.
Application example:
After the elevator door has been opened and closed on one floor, the opening and closing
time can be queried from the door control unit. If the value zero is read as time, this
measurement must be ignored and only the next complete opening or closing movement on
this floor must be taken into account.
The measured times can be compared with a reference value. If a permissible tolerance is
exceeded, this can indicate a mechanical problem in the slow start or slow end mechanics.
