0 - 32.000 pulses which generates an
output signal proportional to the value (0.0-100.0%)
received by serial communication. Writing from Serial
communication is done to parameter 364 (terminal
42) and 365 (terminal 45). This function is limited to
the following protocols: FC bus, Profibus, LonWorks
FTP, DeviceNet, and Modbus RTU.
Motor alternation A relay or digital output can be used
in conjunction with output contactors to alternate the
frequency converter ’ s output between motors based
on an internal timer. See parameters 433 and 434 for
further information and programming information.
320 Terminal 42, output, pulse scaling
(AO 42 PULS SCALE)
Value:
1 - 32000 Hz
✭
5000 Hz
Function:
This parameter allows scaling of the pulse output signal.
Description of choice:
Set the desired value.
321 Terminal 45, output
(AO 45 FUNCTION)
Value:
See description of parameter 319 Terminal 42, Output.
Function:
This output can function both as a digital or an analog
output. When used as a digital output (data value
[0]-[26]) it generates a 24 V (max. 40 mA) signal. For
the analog outputs (data value [27] - [41]) there is a
choice of 0-20 mA, 4-20 mA or a pulse sequence.
Description of choice:
See description of parameter 319 Terminal 42, Output.
