5-5 Setting the Frequency Reference
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 six frequency references in n03.
Local mode: Select and set one out of two frequency references in n07.
Selecting the Frequency Reference (n03) in Remote Mode
• Select the input method of frequency references in remote mode.
• Five frequency references are available in remote mode. Select one of
them according to the application.
Set Values
Note 1. The maximum frequency (FMAX) is set when the FREQ adjuster is set to
MAX.
2. The maximum frequency (FMAX) is set with 10 V input.
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.
Selecting the Frequency Reference (n07) in Local Mode
• Select the input method of frequency references in local mode.
• Two frequency references are available in local mode. Select one of them
according to the application.
