6.5 Testing with heavy loads
Refer to the elevator level installation manuals for the safety inspection procedure of each
elevator.
Follow the safety instructions and precautions that are described for each elevator type
individually.
Step Action Note
1 Activate Enable traction test (6_72)
parameter.
No one is allowed to be in the car.
Enable traction test (6_72) parameter
increases the value of the supervision
limit between the speed reference and
tachometer feedback
for one drive.
The buzzer sounds continuously when
the traction testing is enabled.
Even if the load in the car exceeds
110 % of the rated load, the
information that the drive gives the
elevator control is exactly 100 %.
However the drive itself uses the correct
load value for driving.
2 If the motor does not rotate, adjust the value of
Torque scaling (6_40) parameter
temporary higher up to 3.0.
3 Check the value of
MXTORQ (6_9) parameter (max. 4.8 V), if the drive fails
reactivate the test.
