10.2 INVERTER COMMISSIONING

All activities below described can be performed alternatively with the BOP or by PC
ATTENTION: You must do self-learning inverter before performing any calibration, in order to
adapt its behavior to the installation characteristics.
To run the self-learning inverter correctly, do the following:
1. Install and set up the system completely (electrical connections, piping, oil filling the tank,...)
2. make sure you have the weight that can be loaded to reach the maximum working pressure of the
system (Pmax)
3. Only if you use PC commissioning, Start the STARTER program, connect the PC ONLINE to the device
via the yellow button
4. Only if you use PC commissioning, Navigate to the parameter list User S120 Low
5. Make sure the oil temperature (see parameter r21695 Drive) is within the range Tmin = 20 ° C and
Tmax = 30 ° C. In case Toil<20 ° C, run a few cycles of movement up and down to increase the T oil. If
Toil>30 ° C, let the oil cool with the system is shut down. If you use PC commissioning, the parameter is
inside the parameters family AUTOTUNING,
6. Run the self-learning without load (
 Remove any load from the cab
 Set the parameter P21600=1H and then press ENTER
 Perform a normal cycle of ascent and descent of the lift
 Set the parameter P21600 = 0H and press ENTER
In this way, the new torque values detected at empty conditions, that are visible to the parameters
r21620 and r21621, are copied and saved in the parameters of the inverter use P21590 and P21595.
7. Run the self-learning at full load (
 load the cab with weights to reach Pmax
 Set the parameter P21601=1H and then press ENTER
 Perform a normal cycle of ascent and descent of the lift
 Set the parameter P21601 = 0H and press ENTER
 In this way, the new torque values measured at full-load conditions, that are visible to the parameters
visible to r21622 and r21623, are copied and saved in the parameters of the inverter use P21591 and
P21596.
ATTENTION: If the Toil is outside of the range Tmin / Tmax values of auto-tuning will not be captured
and torque values may be setup to 0!
ATTENTION: If you do not set the parameter to 0H at the end of the test, the system will remain under
self-learning conditions and the system does not work properly.
ATTENTION: If during the procedure is missing voltage, the torque values remain set to 0! Repeat the
tuning after restoring power.
ATTENTION: If you calibrate under conditions other than empty / full load, the torque values recorded
may not ensure proper operation of the system under all conditions.
At this point the system is ready to be used and configured.
Any additional tune-up can be done by acting directly on the values of the parameters of the drive available
in the list "User S120".
ATTENTION: Only in case of change of the inverter or of the electric motor, you must do motor
recognition by P1910, before performing any calibration. Please contact Omarlift Service, for the
procedure.
