Operating (RUN/STOP Commands) Using Communications
(When Option Card is Installed)
Setting constant n02 to 2 in REMOTE mode enables using RUN/STOP commands via MEMOBUS communications. For commands using
MEMOBUS communications, refer to page 83.
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 for selecting the mode, refer to page 48.
LOCAL Mode
Select command method using constant n07.
n07=0: Enables using the potentiometer on the Digital Operator
(initial setting).
The factory setting for models with the Digital Operator
(without a potentiometer) is n07=1.
=1: Enables digital setting on the Digital Operator, setting value is
stored in constant n21 (frequency reference 1).
• Digital Setting Using the Digital Operator
Input the frequency while FREF is lit (press ENTER after setting the numeric value).
Frequency reference setting is effective when 1 is set for constant n08 instead of pressing ENTER.
n08 =0: Enables frequency reference setting using the ENTER key
(initial setting).
=1: Disables frequency reference setting using the ENTER key.
REMOTE Mode
Select the command method in constant n03.
n03 =0: Enables frequency reference setting using the potentiometer
on the Digital Operator (initial setting).
Factory setting of models with the Digital Operator (without a
potentiometer) is n03=1.
=1: Enables using frequency reference 1 (n21)
=2: Enables a voltage reference. (0 to 10 V) (See the following
figure.)
=3: Enables current reference. (4 to 20 mA) (Refer to page 75.)
=4: Enables current reference. (0 to 20 mA) (Refer to page 75.)
