Chapter 6 - Parameter Description [I/O]
6-49
I/O-46: Inverter Number
I/O-47: Baud Rate
This code sets the inverter number. This number is used in
communication between inverter and communication
board.
This code sets the communication speed. This is used in
communication between inverter and communication
board.
I/O-48: Operating at Loss of Freq. Reference
I/O-49: Waiting Time after Loss of Freq. Reference
There are two kinds of loss of frequency reference. One is
the loss of digital frequency reference and the other is of
analog frequency reference.
Loss of digital frequency reference is applied when DRV-
04 [Frequency Mode] is set to ‘Keypad-1’ or ‘Kepad-2’. At
this time, the ‘Loss’ means the communication error
between inverter and keypad or communication board
during the time set in I/O-49.
Loss of analog frequency reference is applied when DRV-
04 [Frequency Mode] is set to other than ‘Keypad-1’ or
‘Kepad-2’. At this time, the ‘Loss’ is determined by the
criteria set in I/O-11 [Criteria for Analog Input Signal Loss].

Inverter keeps on operating at the
previous frequency.

Inverter cuts off its output.
(Coast to stop)
Stop
2
Inverter stops with Decel time (DRV-
02) and Decel pattern (FU1-26).
This is the time inverter determines whether there is a
frequency reference or not. If there is no frequency
reference satisfying I/O-11 during this time, inverter
determines that it has lost of frequency reference.
I/O-50: Auto (Sequence) Operation
I/O-51: Sequence Number Selection (Seq #)
I/O-52: The Number of Steps of Sequence #
There are two modes of ‘Auto-A’ and ‘Auto-B’ in Auto
mode. Auto operation is activated by the multi-function
input terminals set to [SEQ-L], [SEQ-M], [SEQ-H] and [Go
step] in I/O-12 ~ I/O-14.
This code selects the sequence to set frequency, transient
time, steady speed time and motor direction the steps.
This code sets the number of steps to use for the
sequence number selected in I/O-51.
