Parameter No. Function name
H073 Gain switching time
•If control gain switching is selected in the multi-function input selection, turning off the signal
selects the gain setting of H050, H250, H051, H251, H052, or H252. Turning on the signal selects
the gain setting of H070, H071, or H072.
•If control gain switching is not selected in multi-function inputs 1 to 8 (C001 to C008), the gain
setting conforms to the status in which the signal is turned off.
UP/DOWN Function
•This function allows you to change the Inverter output frequency using the UP and DWN terminals
of the multi-function inputs.
Data Symbol
27 UP
28 DWN
29 UDC
Available input terminals
Note: Do not turn on/off the UP/DWN terminal after shutting off the power. Otherwise, the Inverter may not store
data correctly.
•Allocate "27" (UP) and "28" (DWN) to any of multi-function inputs 1 to 8 (C001 to C008).
•This function is enabled only when frequency reference selection A001 is set to "01" or "02". If "01"
(terminal) is selected, however, this function is enabled for multi-step speed operation only.
•When you use an external analog input as frequency reference input, or when you set the jogging
operation frequency, this function is disabled.
•While the UP/DWN terminal is turned on, the acceleration/deceleration time depends on F002,
F003/F202, F203/F302, and F303. To switch between the 1st/2nd/3rd controls, allocate 08 (SET)/
17 (SET3) to the desired multi-function input and then turn on/off the SET terminal.
•You can store a frequency set value after UP/DWN adjustment. Choose whether to store the value
with C101.
Also, you can clear the stored frequency set value.
By allocating "29" (UDC) to a multi-function input and turning on/off the UDC terminal, you can
clear or store the frequency reference setting adjusted at UP/DOWN.
