12-BATTERY OPERATION
12.1 – Battery voltage (BAT_Volt: 60-120V, 220V UPS)
This is the setting of the back-up power which will be used during evacuation. Either a
60-120V battery pack or a suitably rated 1-phase 220VAC UPS may be used.
12.2 – Battery direciton (BD: EASIEST DIR / COMMAND DIR)
The type of direction during evacuation operation.
Easiest direction: The evacuation direction is determined by the inverter. ADrive ignores
the applied speed and direction commands and starts running the motor in the in the lower
load direction with a maximum allowed speed limited with the parameter
12.3 .
Command direction: The evacuation direction is determined by the lift control system.
Inverter ignores only the applied speed command and starts running the motor in the
direction applied to input terminals UP/DWN with a maximum allowed speed limited with
the parameter
12.3 .
12.3 – Battery speed (V4: 0.05 – 5.00 m/s)
Maximum evacuation speed allowed during evacuation operation.
The maximum speed that can be achieved during evacuation operation depends on the
type of motor and loading of the car (evacuation in the lower-load evacuation or command
direction). Max. allowed evacuation speed is limited to the value of this parameter. Even if the
elevator system allows higher speeds, the car speed will not exceed this value.
12.4 – UPS power (UPS_pw: 0.5 – 20 kW)
This parameter is for protecting the UPS device. It will be visible if “12.1-BAT.VOLTAGE”
parameter is set to “220V UPS”. This is the maximum power which can be drawn from the UPS
during evacuation. The driver prevents the UPS from overloading by limiting its power to this
value.
First of all, the power rating of the UPS must be calculated in kWs. Making of those
calculations are explained on section 13.3.3.1 (for lower-load evacuation) and section 13.3.4.1.
(for command direction evacuation).
