H61 Multistep Frequency + UP/DOWN Control
Terminal commands UP ("Increase output frequency") and DOWN ("Decrease output
frequency") determine the reference frequency by increasing and decreasing the multistep
frequency command being selected, respectively.
H61 provides a choice of terminal command UP/DOWN operation modes as listed below.
Setting the H61 at "13" or above and turning any of SS1 to SS8 ("Select multistep
frequency") ON enables "Multistep frequency + UP/DOWN control."
When no multistep frequency is selected (that is, when F01/C30 applies except F01/C30 = 7),
both UP and DOWN commands do not take effect.
When "Multistep frequency + UP/DOWN control" is enabled, the acceleration/deceleration
time 4 specified by E14/E15 applies.
Run command OFF:
UP/DOWN frequency.
Inverter power OFF: When the power is turned OFF, the inverter saves the UP/DOWN
frequency.
Multistep frequency switching: When a multistep frequency is entered, the inverter saves the
UP/DOWN frequency.
Save UP/DOWN frequency with respect to each multistep frequency: The inverter saves the
UP/DOWN frequency with respect to each multistep frequency.
Clear UP/DOWN frequency with respect to each multistep frequency: The inverter clears the
UP/DOWN frequency by an STZ signal with respect to each multistep frequency.
To use the UP/DOWN frequency, you need to assign terminal commands UP and DOWN to
general-purpose digital input terminals beforehand ( E01 to E07, data = 17, 18)
When H61 = 1, it is necessary to set F01 to "7" (Terminal command UP/DOWN control);
when H61 ≥ 13, it is not.
