The OI input (set value using analog current 4..20mA) will only be used if
the input configured as AT has been closed before. If no digital input has
been configured as an AT input then the set values that are present at termi-
nals O and OI will be added.
Using the FM output the output frequency can be monitored and displayed using
an external analog or digital meter. If needed, the motor current can be displayed

When a digital output is configured as FA1 then a signal
is output as long as the output frequency is held constant
at set value. With a digital output being configured as
FA2, a signal will be output as long as the actual output
frequency is above the values set under C 42 and C 43.
The RUN signal is active as long
as the motor is running.
The OL signal will be output when the actual motor current
is above the threshold set under C 41.
The OD signal will be output when the threshold set under
C 44 (level of PID deviation) is being passed.
The alarm signal is output in case a trip condition occurs.
This is the 0V common for the programmable digital outputs 11 and 12. These
open collector type outputs are isolated using photocouplers and are separated
During normal trouble-free operation the terminals AL0 and AL1 are shorted.
During a trip condition or while power to the inverter is off the terminals AL0 and
