TEST
10) Put the oscilloscope clamp on a network phase and check the waveform. Check the waveform below for other network phases.

11) Load the motor at the variable speed drive’s rated intensity and check that the level of imbalance of the network currents is less
than 8%.
12) Load the motor at the variable speed drive’s rated intensity, for models 570 T to 1710 T: place an oscilloscope clamp on each
motor and network phase inlet and check the waveform and balance for each motor and network phase inlet. Balancing shall
not be less than 7% of full load on the motor side and 10% on the network side.
13) Leave the assembly running for 30 minutes and check the IGBT temperatures in parameters 07.51 , 07.52 , 07.53 and that of
the rectifier bridge in 07.54 , according to the table below.
Note: the various readings below are for a variable speed drive with a 6-PULSE architecture and chassis with built-in AF-type fans,
installed in a RITTAL enclosure, with line reactor and UR fuse as well as additional roof ventilation.

14) Remove the load from the motor, and set the potentiometer to 0% (deceleration of the motor to zero speed)
15) Remove the running order, then set the STO-1 and STO-2 inputs to 0 (open)
16) The test while operating is complete
