7.4 Power-off Battery Driven Run Mode Application
During using elevator, if the system power is off, passengers will be shut in car. HD5L provide
battery driven run mode to resolve this problem.
7.4.1 Basic Connection
Figure 7-4 Basic connection of battery driven run
In the Figure 7-4, the terminal definition is shown as Table 7-4:

DI2 Input terminal signal: UP
DI3 Input terminal signal: DN
DI7 Input terminal signal: Battery driven run command (BAT)
(+)、(－) Controller DC bus voltage terminals
KM Mains power control contactor
7.4.2 Running Time Sequence
1. When mains power fails, the mains power control contactor (KM) opens, and the elevator
controller outputs battery driven running command (BAT).
2. After some time delay, the controller outputs running command (UP/DN). When HD5L receive
the command, the running contactor will be closed and the brake will be opened. HD5L
accelerate at the line rate of F03.08 (Battery driven Acc speed) till the speed of F05.09 (Battery
driven run speed).
3. When the elevator runs near a leveling area, the controller cuts off the battery driven run
command (BAT), and HD5L begin to Dec at the rate of F03.09 (Battery driven Dec speed) to stop.
4. The controller outputs the brake close signal after the speed decelerates to zero. After some
time delay, controller cuts off the running command (UP/DN) and HD5L releases the contactor. A
complete battery driven running process is over.
Note:
1. The battery voltage should be bigger than 240VDC to ensure normal operation.
2. In the battery driven running mode, the controller does not detect the input phase failure.
