Upper And Lower Frequency Reference Limits - Omron SYSDRIVE 3G3MV User Manual

Basic Operation
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 SW2 on
the control PCB is switched from V to I.
Note 4. Set n149 for the pulse train input scale to the pulse train frequency that is equiv-
alent to the maximum frequency (FMAX).
·The frequency reference set in n004 functions as frequency reference 1 when the
Inverter is in multi-step speed operation. The set values in n025 through n031 and
n120 through n127 for frequency references 2 through 16 are enabled.
H Selecting the Frequency Reference (n008) 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

Note 1. The maximum frequency (FMAX) is set when the FREQ adjuster is set to MAX.
Note 2. The frequency reference can be set with key sequences while the FREF indica-
tor is lit or with the set value in n024 for frequency reference 1. In either case, the
value is set in n024.

5-6-2 Upper and Lower Frequency Reference Limits

Regardless of the methods of operation mode and frequency reference
input, the upper and lower frequency reference limits can be set.
