K 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 H1-05 (multi-function terminal inputs S3 to S7 func-
tion 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 command can
be used as a pair.
nRelated Parameters
nTrim Control Increase/Decrease Command and Frequency Reference
The frequency references using Trim Control Increase/Decrease command ON/OFF operations are shown
below.
nApplication Precautions
• Trim Control Increase/Decrease command is enabled when speed reference > 0 and the speed reference is
from an analog input.
• When the master speed frequency reference value from the analog input - d4-02 < 0, the frequency refer-
ence is set to 0.
• The auxiliary frequency reference is added after calculating 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 S7, operation error OPE03 (invalid multi-function input selected)
will occur.
