Accelerating And Decelerating Constant Frequencies In The Analog References (+/- Speed) - Omron SYSDRIVE RV Series User Manual

Accelerating and Decelerating Constant Frequencies in the Analog Refer-
ences (+/- Speed)
The +/− speed function increments or decrements the frequency set in analog frequency reference d4-02 (+/−
Speed Limit) using two contact signal inputs.
To use this function, set One of the parameters H1-01 to H1-06 (multi-function contact terminal inputs S3 to
S8 function selection) to 1C (Trim Control Increase command) and 1D (Trim Control Decrease command). Be
sure to allocate two terminals so that the Trim Control Increase command and Trim Control Decrease com-
mand can be used as a pair.

Application Precautions
Trim Control Increase/Decrease command is enabled when speed reference > 0 and the speed reference is
•
from an analog input.
When the analog frequency reference value − d4-02 < 0, the frequency reference is set to 0.
•
The value of the auxiliary speed-frequency reference is incremented or decremented by the value of the
•
master speed-frequency reference ± d4-02.
If only the Trim Control Increase command or Trim Control Decrease command has been set for a multi-
•
function contact input terminal S3 to S8, operation error OPE03 (invalid multi-function input selected)
will occur.
