ncy Command
The frequency command can be changed temporally when the frequency is added by turning [ADD]
terminal ON.
The frequency command can be subtracted when the sign of the frequency command changes (+) to
(-).
Precautions for Correct Use
• The frequency addition of the input terminal function 014 [ADD] is made within the limited fre-
quency range. If the frequency is not within the range between the upper and lower limits or
exceeds the maximum frequency, the frequency command is restricted.
• If the sign of the frequency command changes ((-) to (+) or (+) to (-)) as a result of the arith-
metic, the rotation direction is reversed.
• This function is also effective for PID target value.
 Parameter
The frequency command of the inverter can be changed by a signal input if 020 [FUP terminal and 021
[FDN] terminal are assigned in the input terminal function.
This function works for the selected frequency command when the frequency command selection
[AA101] is 07 (parameter effective) or when a multi-step speed command is given.
While [FUP] terminal is turned ON, the frequency command increases.
While [FDN] terminal is turned ON, the frequency command decreases.
Acceleration/Deceleration follows Acceleration time setting for FUP/FDN function [CA-64]/Deceleration
time setting for FUP/FDN function [CA-66].
If 01 (save) is chosen in [CA-61], frequency command data changed with [FUP] terminal and [FDN] ter-
minal can be saved when the power supply is cut off. The operation of an inverter can be resumed with
the saved frequency command even after the power supply is cycled. To clear the saved frequency
value, assign 022[UDC] to the input terminal and change the [UDC] terminal from ON to OFF. Clear-
ance by [UDC] follows the designated value of [CA-62].
Precautions for Correct Use
• When 020 [FUP] terminal / 021 [FDN] terminal is made ON/OFF immediately after the power
shutdown, data may not be able to be correctly saved.
• Cannot be used to set the frequency of the input terminal function 029 [JG] jogging operation.
