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

Application 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
Command 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 S8.
To use this function, set one of the parameters H1-01 to H1-06 (multi-function contact input terminal S3 to S8
function 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).
