Function Instructions
3 Multistage speed terminal 1
15-stage speed is realized by combination of this
group of terminals. See Table 9-5.
4 Multistage speed terminal 2
5 Multistage speed terminal 3
6 Multistage speed terminal 4
7 Reset terminal
This terminal has the same function with “reset” key
in keypad.
8 Free stop terminal
Coast Stop
Inverter closes off output and motor stop process
is not controlled by inverter. This mode is often
used when load has big inertia or there are no
requirements for stop time. This mode has the
same function with free stop of F209.
9 External coast stop terminal When external malfunction signal is given to
inverter, malfunction will occur and inverter will
stop.
10 Acceleration/deceleration
forbidden terminal
Speed Hold
Inverter will not be controlled by external signal
(except for stop command), and it will run at the
current output frequency.
11 Forward run jogging Forward jogging running and reverse jogging
running. Refer to F124, F125 and F126 for jogging
running frequency, jogging
acceleration/deceleration time.
12 Reverse run jogging
13 UP frequency increasing terminal
When frequency source is set by digital given, the
setting frequency can be adjusted which rate is
set by F211.
14 DOWN frequency decreasing
terminal
15 “FWD” terminal When start/stop command is given by terminal or
terminals combination, running direction of
inverter is controlled by external terminals.
16 “REV” terminal
17 Three-line input “X” terminal
“FWD”、“REV”、“CM” terminals realize three-line
control. See F208 for details.
18 Acceleration/deceleration time
switchover 1
Refer to table 9-4.
21 Frequency source switchover
terminal
When F207=2, main frequency source and
secondary frequency source can be switched over
by frequency source switching terminal. When
F207=3, X and (X + Y) can be switched over by
frequency source switching terminal.
32 Fire pressure switchover When PID control is valid and this terminal is valid,
the setting value of PID switches into fire pressure
given (FA58).
33 Emergency fire control When emergency fire mode (FA59) is valid, inverter
will be in emergency fire mode.
34
Acceleration / deceleration
switchover 2
Please refer to Table 9-4.
37
Common-open PTC heat
protection
When this function is valid, common-open heat
relay is externally connected. When
common-open contact is closed and inverter is in
the running status, inverter will trip into OH1.
38
Common-close PTC heat
protection
When this function is valid, common-close heat
relay is externally connected. When
