More about control outputs:
"FAULT": This output is a relay contact and consists of two connector pins. It indicates the general
drive status.
The FAULT relay contact is not suitable for switching inductive
loads (relays). Inductive loads can cause some nuisance drive
faults.
"DrOK": This output has the same functionality than the fault relay output. The output (+24V) is
activated in case the drive is ready for work.
"DOUT x": These outputs can be used together with the drive internal PLC program. There are 2 digital
outputs available.
