7.18 Advanced door opening
An advanced door opening output can be configured on the E300 Advanced Elevator drive. This feature provides an output to the Elevator controller
to open the elevator car doors at a defined speed prior to the elevator car reaching the floor level. This allows the Elevator travel times to be reduced.
The advanced door opening output is generated based upon a speed threshold and routed to a digital output to the Elevator controller.
The advanced door opening speed threshold is configured by the user in Velocity Threshold 1 (H13). In addition there is also an invert for the output
and status bit.

7.19 Emergency backup power supply control
IIn order to prevent a UPS system from being overloaded during emergency back up operation, there are two features within the software which will
control both the current limit and speed to limit the output power demand from the UPS. The UPS protection requires the user to enter the UPS power
rating into UPS Maximum Power Set point (O06). The protection then uses this value as the maximum power allowed and compares this with the
actual drive output power.
When UPS Control Enable (O05) = On (1), UPS control is has been enabled using a digital input from the Elevator controller routed to the UPS
control enable parameter. When the UPS control enable is active, the following functions are internally controlled to reduce the loading on the UPS
and extending the operating time:-
• UPS maximum power setpoint
• Symmetrical current limit
• Start optimizer is disabled
• Start position lock is disabled
• Load measurement is disabled
• Maximum speed error threshold is disabled
• Maximum distance error threshold is disabled
To protect the UPS from overloading and switching into standby mode, the DC bus voltage control of Symmetrical Current Limit (B16) is carried out
with the UPS control.
Where the DC bus voltage drops below the UU Reset voltage + 60 V (= 510 Vdc for 400 Vac drives), the current limit is decreased linearly from the
nominal set value in UPS evacuation current full load limit (O07) to the reduced value in UPS evacuation current no load limit (O08) with the redcution
in voltage to 450 Vdc.
The speed is also controlled to prevent exceeding the power set point in UPS Maximum Power Set point (O06) in kW. When the output power is >
UPS maximum power set point, the speed reference will be internally set to 0.
