With the EL-S-shape pattern, you can set the EL-S Shape Acceleration/Deceleration Curve Ratio
parameters (A151 to A153).
Setting all of these parameters to 50 [%] is equivalent to selecting the S-shape pattern.
• The calculation frequency function enables the use of calculation results from two analog input
channels for the frequency reference and the PID feedback value.
When this function is enabled, the Multi-function Input S1 to S8 Selection (C001 to C008) cannot
be set to 27, 28, or 29 to enable the UP/DWN function. In addition, the frequency settings of the
Output Frequency Monitor (d001), Output Frequency Monitor (After Conversion) (d007), and
Output Frequency Setting/Monitor (F001) cannot be changed via the Digital Operator keys.
A141 and A142 can have the same setting.
• To use this function for the frequency reference, set the Frequency Reference Selection
(A001) to 10 (Operation function output).
• To use this function for the PID feedback value, set the PID Feedback Selection (A076) to 10
(Operation function output).
