When using the trickle and de-ice feature, pay attention to the settings below. These two features default to "DISABLE" so
you will need to set them to EFB control. Note that setting 75.03 Run Time to zero, will cause the function to stay on as long
as the CW bit calls for it (no time limit).

Troubleshooting:
You can verify the CW being received by the drive by looking at par 58.18 EFB Control Word. This will be the raw value being
sent by the PLC.
You can verify the current speed reference in rpm being used by the drive by looking at par 3.09 EFB Reference 1.
You can verify the SW being sent by the drive to the PLC by looking at par 58.19 EFB Status Word. This value is shown in
HEX by default, so convert to decimal before comparing it to the number you see in ModbusPoll. In DriveComposer, you can
also right click this value and show it as decimal – or any other number format you like.
