03-27=3:
Keep the state of frequency command not to be cleared. When run command re-sends, press UP/DOWN key
before the run frequency reaches the frequency command.
Code Parameter Name / Range
03-40 Up/Down Frequency Width Setting
0.00~5.00 Hz
When 03-40 is set to 0 Hz, Up / Down function is maintained.
When 03-40 is not set to 0 Hz, frequency command is set by the run frequency plus the setting frequency of
03-40.
Example: set terminal S1: 03-00=8 (Up increased frequency command), terminal S2: 03-01=9 (Down de-
creased frequency command) and 03-40= ∆Hz.
Mode 1: When 03-40 is set to 0 Hz, Up / Down function is maintained. Refer to Fig. 4.4.20.
Mode 2: When 03-40 is not set to 0 Hz and terminals conduction time < 2 s, frequency change (∆Hz) at one
conduction occurs depending on the setting of 03-40.
