• Communication/multi-function input terminal selection input (setting: 18)
(This function is effective when option card is installed)
Operation can be changed from communication command, or from multi-function
input terminal or digital operator command.
Run command and frequency reference from communication options are effective
when multi-function input terminal for this setting is “closed.”
Run command and frequency reference in LOCAL/REMOTE mode are effective
when “Open.”
Multi-function output terminal MA and MB functions can be changed when necessary
by setting parameter n40.
• Terminal MA and MB functions: Set to n40
Using output signals (n40)
Setting Name Description Ref page
0 Fault Closed when inverter fault occurs. –
1 Inverter Run
Closed when either FWD/REV command is input or
voltage is output from the inverter.
–
2 Agreed frequency
Closed when setting frequency agrees with inverter
output frequency.
88
3 Zero speed
Closed when inverter output frequency is less than
minimum output frequency.
–
4 Frequency detection Output frequency ≥ frequency detection level (n58) 74
5 Frequency detection Output frequency ≤ frequency detection level (n58) 74
6
Overtorque detection
(NO contact output)
—73
7
Overtorque detection
(NC contact output)
—73
10 Minor Fault Closed when the alarm is indicated. –
11 Base blocked Closed when the inverter output is shut off. –
12 Operation mode
Closed when “LOCAL” is selected by LOCAL/REMOTE
selection.
–
13 Inverter ready
Closed when inverter fault is not detected, and
operation is ready.
–
14 Fault restart Closed during fault retry –
15 In UV Closed when undervoltage is detected. –
16 In reverse run Closed during reverse run. –
17 In speed search Closed when inverter conducts speed search. –
18
Data output from
communication
Operates multi-function output terminal independently
from inverter operation (by MEMOBUS
communication).
