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)
6
The frequency reference via RS-422A/485 communications is enabled.
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 references 2 through 8 are enabled.
H
