Selecting Run/Stop Commands
Refer to Switching LOCAL/REMOTE Modes (Page 44) to select either the
LOCAL mode or REMOTE mode.
Operation method (RUN / STOP commands, FWD / REV run commands) can be selected by the following method.
•
LOCAL Mode
When Lo (local mode) is selected by digital operator ON mode, or when the LOCAL / REMOTE switching function is set and the input terminals are turned ON, run operation is enabled by the and FWD/REV run is selected by
or
ON mode (using
of the digital operator,
or key).
•
REMOTE mode
• Select remote mode.
The following two methods are used to select remote mode:
1. Select rE (remote mode) by selection.
2. When the local / remote switching function is selected by multi-function input selection, turn OFF the input terminal to select remote mode.
• Select operation method by setting the parameter n003.
n003 =0: Enables the digital operator (same with local mode)
=1: Enables the multi-function input terminal (see fig. below)
=2: Enables communications
=3: Enables communication card (optional)
• Example for using the multi-function input terminal as operation reference
(two-wire sequence)
Below shows the example of three-wire sequence, (Refer to page 70.)
)
For example of three-wire sequence, refer to page 70
Note: When inverter is operated without the digital operator, always set the parameter n010 to 0.

Operating (RUN /STOP commands) by communications
Setting parameter n003 to 2 in REMOTE mode can give RUN / STOP commands by communication (MEMOBUS communications). For the command by transmission, refer to page 89).
•
Selecting Frequency Reference
Frequency reference can be selected by the following methods.
•
Setting by operator
Select REMOTE or LOCAL mode in advance. For the method of selecting the mode, refer to page 44.
LOCAL mode
Select command method by parameter n008.
n008 =0 : Enables the setting by potentiometer on digital operator.
=1 : Enables the digital setting by digital operator. (Initial Setting)
Factory setting of the model with digital operator (with
potentiometer) JVOP-140 is n008=0.
• Digital setting by digital operator
Input frequency while FREF is lit (press ENTER after setting the numeric value).
Frequency reference setting is effective when 1 (initial setting : 0) is set to parameter n009 instead of pressing ENTER key.
n009 =0 : Enables frequency reference setting by ENTER key.
=1 : Disable frequency reference setting by ENTER key.
REMOTE mode
Select command method by parameter n004.
n004 =0 : Enables frequency reference setting by potentiometer on digital
operator.
=1 : Frequency reference 1 (n024) is effective (Initial setting)
Factory setting of the model with digital operator (with potentiometer)
JVOP-140 is n004=0
=2 : Voltage reference (0 to 10V) (See the figure on page 47)
=3 : Current reference (4 to 20mA) (Refer to page 81)
=4 : Current reference (0 to 20mA) (Refer to page 81)
=5 : Pulse train reference (Refer to page 82)
=6 : Communication (Refer to page 90)
=7 : Voltage reference of digital operator circuit terminal (0-10)
=8 : Current reference of digital operator circuit terminal (4-20mA)
=9 : Communication card (optional)
