5-5-1 Selecting the Frequency Reference
The
following description provides information on how to set the frequency
reference in the Inverter. Select the method according to the operation
mode.
Remote mode:Select
and set one out of
five frequency references in n03.
Local mode: Select
and set one out of two frequency
references in n07.
H Selecting the Frequency Reference (n03) in Remote Mode

Set Values
Value Description
0 The FREQ adjuster of the Digital Operator is enabled. (see note 1)
1 Frequency reference 1 (n21) is enabled.
2 The frequency reference control terminal (for 0- to 10-V input) is enabled.
(see note 2)
3 The frequency reference control terminal (for 4- to 20-mA current input) is
enabled. (see note 3)
4 The frequency reference control terminal (for 0- to 20-mA current input) is
enabled. (see note 3)
Note 1. The
maximum frequency (FMAX) is set when the FREQ adjuster is set to
MAX.
Note 2. The maximum frequency (FMAX) is set with 10 V input.
Note 3. The
maximum frequency (FMAX) is set with 20 mA input, provided that SW8 on
the control PCB is switched from V to I.
•The
frequency reference set in n03 works as frequency reference 1 when the Inverter
is
in multi-step speed operation. The set values in n22 through n28 for frequency refer
-
ences 2 through 8 are enabled.
