When set to Off (0), UPS control is disabled.
When set to On (1), UPS control is enabled, where an elevator drive digital input from the elevator controller routed to UPS Control Enable (O05).
When UPS Control Enable (O05) = On (1), the following functions are internally controlled to extend the operating time of the UPS:
• Symmetrical Current Limit (B16)
• Start Lock Enable (I22)
• Maximum Speed Error Threshold (H15)
• Maximum Distance Error Threshold (H16)
• Start Optimizer Time (G48)
• Load measurement time (O04)
To protect the UPS from overloading and switching into standby, DC bus voltage control of the current limits is activated by setting UPS Control
Enable (O05) = On (1).
If the DC bus voltage decreases below the UU Reset voltage + 60 V (= 510 V for 400 V drives), the current limit will be decreased linearly from the
nominal set value to UPS evacuation current full load limit (O07) at low load and 510 Vdc linearly to the reduced value in UPS evacuation current no
load limit (O08) at full load, 450 Vdc.
The speed is also controlled to prevent exceeding the power setpoint in UPS Maximum Power Setpoint (O06) in kW. When Output Power (J59) is >
UPS Maximum Power Setpoint (O06), the speed reference will be internally set to 0.
The following logic diagram shows the UPS control features activated by setting UPS Control Enable (O05) = On (1):
