There is a known issue when operating the S100 VFD with an EtherCAT card and an HOA switch. This problem can occur when the VFD is using a digital input to switch to "2nd source". In theory, the "HAND" mode should disregard the status of the EtherCAT run bit.  It has been found that in practice the run bit needs to be enabled. LS Electric is currently working on an update to the EtherCAT card for this issue.
