Raising And Lowering Frequency References Using Contact Signals (Up/Down) - Omron SYSDRIVE 3G3RV Series User Manual

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.

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).

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.
Description
Set the output frequency upper limit as a percent,
taking the maximum output frequency to be 100%.
Set the output frequency lower limit as a percent-
age of the maximum output frequency.
Set the master speed frequency reference lower
limit as a percent, taking the maximum output fre-
quency to be 100%.
