7.6.2 Time sequence of emergency operation
1. When main power supply blacks out, the main power contactor (KM) is disconnected, then control switch
(KW2) of UPS closes and outputs emergency operation command (BAT) after a period of delay time;
2. After another a period of delay time, the controller outputs operation command (X1/X2). When the
inverter receives operation commands, it closes the operation contactor and releases the brake, then accelerates
from a speed set by F05.09 (acceleration/deceleration speed during emergency operation) to a speed set by F03.08
(Emergency operation speed);
3. When the elevator runs to leveling position, the controller cancels emergency operation commands (BAT),
so the inverter decelerates to stop at F05.10 (Deceleration speed during emergency operation);
4. When the speed of the elevator decelerates to 0, the inverter closes the brake. Then the controller cancels
operation command (X1/X2) after a delay time, and the inverter will release the contactor. So the emergency
operation is ended.
