Please Help What have you assigned for DO #2? Can you assign it a 1, then a 0? Is the 2nd output only NC? Did it ever work or is this a new drive commissioning?

For example, you can set the DOs to "drive ready", "drive fault", "drive running", "disabled" (and other functions). The drive inputs should be powered from the drive's 24V supply according to the drive documentation as opposed to external 24V source for the 240S family. Is the 240E family expecting power from external 24V source?

Vithani I think best thing to do is contact your nearest Siemens repair center and get it repair This is the case with all the CUs of this series of control unit.

This is a transistor output. Are you using the internal or external 24V supply?. There is a connection example in the manual for this output.

You have three digital output signals. DO 0 Pins: 18, 19 & 20 DO 1 Pins: 21 & 22 DO 2 Pins: 23, 24 & 25 Please see the connection diagram attached. And also you can check if the DO signal is already energized or not from reading status parameters: DO 0 Status Parameter: r0747.0 DO 1 Status Parameter: r0747.1 DO 2 Status Parameter: r0747.2 Hope it helps.
