Before enabling the test:- If an external power supply is being used, disconnect thepower module and leave only the supply to the electronics.- If an internal power supply is being used for the electronics,disconnect the internal wiring and connect an external powersupply, so as to disconnect the power module and leave onlythe electronics supplied with power. (For this connection, referto the installation manual, sections 1 and 3 for the driveconcerned.)All I/O and relays must also be disconnected. The test onlystarts if the bus voltage is less than 50 V. The test result isdisplayed in parameter 17.05.At the end of the test, an automatic reset is carried out (equivalentto the reset when the drive is powered down and then powered upagain), in particular a reset to zero of parameters 17.33 to 17.39,17.42 to 17.49, and 17.52 to 17.59).After the test, reconnect everything.No (0):The board test is not enabled.Yes (1):The board test is enabled.17.02 : Power module testAdjustment range : No (0) or Yes (1)Factory setting : No (0)Format: 8 bits• During this test, current is flowing in the motor.Note: This test is available only for POWERDRIVEMD2S or MD2CS versions (the drive must control thepreloading of capacitors on the DC bus, therefore 10.75must be set to No (0)).This test consists of checking that the power circuits areworking correctly.No (0):The power test is not enabled.Yes (1):The power test is enabled. If the bus voltage is higher than70 V, the drive waits for the bus to discharge naturally (this cantake over 5 minutes). For the test to work, the Safe Torque Offinputs must be closed. If this is not the case, a «Diagnostic» tripis generated and the test result 17.06 indicates «Error STOnot connected».17.03 : Power module autotestAdjustment range : No (0) or Yes (1)Factory setting : Yes (1)Format: 8 bits• Caution, during this test, current is flowing in themotor.Note: This self-test is available only for standardPOWERDRIVE MD2S or MD2CS versions (the drive mustcontrol the preloading of capacitors on the DC bus,therefore 10.75 must be set to No (0)).This self-test is recommended for checking the powercomponents on each power-up. It lasts for less than 5 secondssince, in this instance, the bus is not loaded. It is the same testas in 17.02.No (0):The power self-test is not enabled.Yes (1):Enabling of the power module test, which will be performedeach time the drive is powered up.To work, the STO inputs must be closed.At the end of the test, if a «Diagnostic» trip appears, readthe result of the power module test in 17.06, and then getin touch with your usual LEROY-SOMER contact.17.04 : Not used17.05 : Control and interface board test resultAdjustment range : Processing (0), Passed (1),Error control board (2),Error interface board (3), None (4)Format: 8 bitsProcessing (0):The test is in progress. If this state lasts for several seconds,check that the power module has been disconnected (only theelectronics should still be supplied with power) and that the busvoltage is less than 50 V.Passed (1):The test has been performed successfully, or has not yet beenenabled.Error control board (2):A problem has been detected on the control board. The«Diagnostic» trip is triggered. Check that the conditions givenin 17.01 have been complied with. If so, note the values of17.08 and 17.09 and get in touch with your usual LEROY-SOMER contact.Error interface board (3):A problem has been detected on the interface board. The«Diagnostic» trip is triggered. Check that the conditions givenin 17.01 have been complied with. If so, note the values of17.08 and 17.09 and get in touch with your usual LEROY-SOMER contact.None (4):No test has been performed.
