Selecting Functions 5-37
5
1) Monitoring (monitoring of various data,
confirmation of function code data)
2) Frequency setting
3) Operation command (FWD, REV and
other commands set for digital input)
4) Function code data writing
Setting range: 0 to 3

1 Valid Invalid
2 Invalid Valid
3 Valid Valid
The validity of communication can be switched
by a digital input. Set the link functions available
through communications.
The monitor function and function code data
writing function are always valid. When the
communication is disabled by means of a digital
input, a state similar to setting "0" is obtained.
RS485 (address)
to
RS485 (Response interval)
•
Set the various conditions of RS485
communication. Set according to the
specifications of the host unit. Refer to
section 9-4 for protocol and other
specifications.
•
Set the station address of RS485.
Setting range: 1 to 31
RS485 (Mode select on no response
error)
•
Set the communication error handling
process and the error handling timer value.
Setting range: 0 to 3

Setting Communication error handling process
0 Immediate Er 8 trip (coast to stop)
1 Operation continues until the timer time
elapses, then Er 8 trip.
2 Operation continues and retry is made
until the timer time elapses, then Er 8
trip upon a communication error or
continuation of operation upon no
communication error.
3 Operation continues.
RS485 (Timer)
•
Set the error handling timer value.
Setting range: 0.0 to 60. 0 s
RS485 (Baud rate)
•
Set the transmission speed.

RS485 (Data length)
•
Set the data length.
H35
RS485 (Parity check)
•
Set the parity bit.
H36
RS485 (Stop bits)
•
Set the stop bit.
H37
RS485 (No response error detection
time)
•
In a system where there is always an access
to the station at certain intervals, no access
caused by broken wire or other errors is
detected and the inverter trips in Er8.
Setting range:
0 to 60 s
0: No detection
RS485 (Response interval)
•
Set the time taken until a response is sent
back to the host unit upon a request.
Setting range: 0.00 to 1.00 s
