Number of operating hours
The counter is incremented every hour, after 60 minutes of operation in each case, and
stored retentively. After a restart, the minute count restarts from zero. The counter for the
operating hours cannot be deleted.
Total electrical and mechanical energy of the motor (only available as of FW Version AT40 V01.46
and ATD400V V01.07)
● Total electrical energy consumed by the motor
● Total mechanical energy output by the motor
The electrical energy consumed by the motor and the mechanical energy generated are
continuously measured.
The energy values correspond to the current values at the time of the query. The energy
consumption can be determined for different situations by calculating the energy difference
between two points in time.
The measured electrical energy does not take into account the control unit's own energy
consumption.
The energy values are retentively stored every hour. After a restart, the energy
measurement starts with the last retentively stored value.
NOTICE
After a power failure, the energy values are reset to the last stored value.
If the door is obstructed, or if there is an opening or closing command in the end positions,
the motor is energized but the door does not move. This means that the electrical energy
consumed by the motor increases continuously, but the mechanical energy generated
remains unchanged.
Application example:
Upon arrival on one floor and before leaving the floor, the total energy can be queried from
the door control unit. The difference between the two energy values corresponds to the
converted motor energy for one floor. Since all door movements, i.e. even travel with
obstruction and reversing, are taken into account here, the energy requirement can be
calculated for each travel.
