Remote Operation Function (UP/DWN)

Use this function to change the inverter output frequency via the multi-function input terminals UP and
DWN.
Set the Multi-function Input S1 to S7 Selection (C001 to C007) to 28 (UP) and 28 (DWN).
When the UP/DOWN terminal is ON, the inverter operates according to the acceleration/deceleration
time settings (F002/F202, F003/F203, etc.)
In addition, setting C101 to 01 (Store frequency data) enables the inverter to store the frequency refer-
ence value after UP/DWN adjustment into its internal EEPROM when the power supply is shut off.

Output frequency
• The remote operation function is enabled only when the 1st/2nd Frequency Reference Selection
(A001/A201) is set to 01 (Control circuit terminal block) or 02 (Digital Operator), or when the
multi-step speed operation function is enabled. However, the parameter can be set to 01 (Control cir-
cuit terminal block) only when the analog command hold function (AHD) is enabled. For details on
the analog command hold function, refer to 7-3-3 Analog Command Hold Function (AHD) on page
7-24.
• The remote operation function is disabled for the frequency reference via non-held analog input or for
jogging operation.
• To clear the frequency reference value adjusted using the UP/DWN function, set the Multi-function
Input S1 to S7 Selection (C001 to C007) to 29 (UDC).
Then, set the command reference value after clearing in the UP/DWN Clear Selection (C104).
