The easiest way to test this is from the Control Panel in STARTER. There should be an LM button which will start the ALM. You will know it has started becuase the IGBT's start firing and you can hear the carrier frequency. Once started you should be able to run the servo axis from the Control Panel. If you want to start the LM from a binary signal P840 in the line module control word is the On/Off command. A few things to keep in mind with the ALM and I am taking for granted you are asking about a booksize ALM. 1. The EP terminal will need 24V to enable pulses 2. The axis connected on the DC bus the LM feeds need the "line module enabled" signal P864 to run. This should be connected from the LM status word either over Drive CLiQ or if the LM does not have Drive CLiQ wire it in. DoNOT set P864 on the axis to a constant "1" because once power is applied to the ALM the DC bus is charged through the precharge resistors and flying diodes. If you run the axis without the ALM being turned on you will draw current through the precharge resistors and damage the LM. 3. Always use the AIM or ALM reactor specified in the catalog. 4. If your supply voltage is over 415V the ALM will default into Smart mode. There is another forum entry already on how to run in Active mode with 460V.
