Terminal function Description
P24
24V DC common for
digital inputs
Common terminal for the intelligent digital inputs
H

potentiometer)
O

analog input (0-10V)
OI
Frequency set value
analog input (4-
20mA)

inputs
H O OI L
Pot (1k – 2K)
H O OI L
0 - 9,6V DC (rated value 10V)
Input impedance 10k Ohms
H O OI L
4 - 19,6mA DC (rated value 20mA)
Input impedance 250 Ohms
Set value configured

using voltage input:
Set value configured
using current input:
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 terminals O and OI will be added.
FM Frequency monitor
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 instead of the frequency.

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 .
RUN
(00)
RUN signal
The RUN signal is active as long
as the motor is running.
OL
(03)
Overload signal
The OL signal will be output when the actual motor
current
is above the threshold set under C 41 .
OD
(04)
PID deviation signal
The OD signal will be output when the threshold set
under
C 44 (level of PID deviation) is being passed.

Alarm signal The alarm signal is output in case a trip condition
occurs.
Connection of a
signal relay to
digital output 11 or
12:
CM2

Open collector
type output
(max. 27VDC, 50mA)
CM2 0V
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
from L common.
AL0
AL1
AL2
Alarm terminals
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 AL2 are shorted instead.
Absolute maximum relay contact ratings:
250VAC; max. load of 2.5A (purely resistive) or 0.2A (at an cos phi of 0.4)
30VDC; max. load of 3.0A (purely resistive) or 0.7A (at an cos phi of 0.4)
Minimum relay contact ratings:
100VAC at a load of 10mA or 5VDC at a load of 100mA
