The inverter can only be started if an active enabling signal (12-15 V) is applied to the
control terminal rail. If this signal fails during drive operations, the motor will shut down
and coast to a standstill. The shutdown immediately affects the inverter power section.
This signal is provided by an orange wire connected to the number 3 connection on the
terminal rail in the Roll Down. If this wire is not connected this error will occur.
