8.9.7 Adjustment of weighing compensation
When the synchronous master adopts UVW encoder or pulley drives the asynchronous motor, the
device for weighing compensation will be necessary. If it is installed at the rope end of the engine
room, the compensation signal will be connected to AI1 and GND of EC160 main board, P4_24=2.
If it is installed on the weighing proximity switch at the car bottom, P4_24=1.
 When OL voltage>FL voltage>LL voltage, set F0_17 bit1 to 1, that is, +2
on the original parameter.
If the OL and FL signals of the elevator adopt analog weighing voltage of car top board, EC160
autotuning at LL, FL and OL in sequence will be needed, as shown below:
1. Fix the weighing sensor approaching to the center of the bottom and place it in horizontal, about
20mm from the car bottom;
2. Set P4_23 to 1, P4_24 to 1;
3. In inspection, keep the car at light load, adjust the position of the sensor, and input voltage about
8V to car top board (monitor by checking analog input voltage of U1_32)
4. Enter into following setting interface. Data will be saved after finishing autotuning in sequence.
