nApplication Precautions
• When d4-01 is set to 1, the output frequency on hold is stored even after the power supply is turned OFF. If
performing operations using this frequency after the Inverter has also been turned OFF, input the run com-
mand with the Acceleration/Deceleration Ramp Hold turned ON.
• When d4-01 is set to 0 and a run command is input while the Acceleration/Deceleration Ramp Hold is
turned ON, the output frequency will be set to zero.
• If you input an Acceleration/Deceleration Ramp Hold command by error when decelerating during posi-
tioning, deceleration may be canceled.

K Raising and Lowering Frequency References Using Contact Signals (UP/
DOWN)
The UP and DOWN commands raise and lower Inverter frequency references by turning ON and OFF a multi-
function contact input terminal S3 to S7.
To use this function, set one of the parameters H1-01 to H1-05 (multi-function input terminal S3 to S7 func-
tion selection) to 10 (UP command) and 11 (DOWN command). Be sure to allocate two terminals so that the
UP and DOWN commands can be used as a pair.
The output frequency depends on the acceleration and deceleration time. Be sure to set b1-02 (Run command
selection) to 1 (Control circuit terminal).
nRelated Parameters
nPrecautions
When setting and using UP and DOWN commands, observe the following precautions.
Setting Precautions
If multi-function input terminals S3 to S7 are set as follows, operation error OPE03 (Invalid multi-function
input selection) will occur:
• Only either the UP command or DOWN command has been set.
• UP/DOWN commands and Acceleration/Deceleration Ramp Hold have been allocated at the same time.
