Chapter 6 - Parameter Description [I/O]
6-57
Likewise if “V1” is chosen as feedback (APP-06),
parameter APP-32, “meter V max” is the maximum
value of the feedback voltage (default is 10V)
corresponding to the maximum PSI value, I/O-87.
Scaling of feedback signal “V1”.
Param User setting Description
I/O-86 PSI Units select
I/O-87 100.0 PSI Max. Pressure
APP-06 V1 Feedback select
APP-32 10 V Max. Feedback signal
at Max. Pressure
Note: When APP-02, APP-80 or APP-62 are set to
“No”, units in I/O-86 are not used, all parameters
default to Speed [Hz].
I/O-90: Inverter Number
I/O-91: Baud Rate
I/O-92: COM Lost Cmd
I/O-93: COM Time Out
I/O-94: Delay Time
I/O-90 [Inverter Number] sets the drives ID number for
RS-485/Modbus communication.
I/O-91 [Baud rate] sets the communication speed.
Terminals C+ and C- are used for RS-485
communication.
I/O-92 [Com Lost command] determines the method of
operation if the communication signal is lost. If lost,
the drive will display LOR on the LCD display.
The possible functions for I/O 92 are shown in the
following table:
Setting Range Description
None
Continuous operation after loss of
communication signal.
FreeRun
Drive cuts off its output after
determining loss of communication
signal.
Stop
Drive stops by its Decel pattern and
Decel time after determining loss of
communication signal.
I/O-93 [Communication time out] sets the delay time
before the drive faults after the communication signal
is lost. When lost, the drive will display LOR on the
LCD display.
I/O-94 setting is for communications using RS232-
RS485 converters. It should be set properly according
to RS232-RS485 converter specification.
