P40 [Frequency Setting Method]
Step 1. Set P40 [Frequency Setting Method] to "5".
Step 2. Override function available using Main/Auxiliary speed adjustment
Step 3. Related code: t36, t39, t40, t44, t45, t49
Override function allows more precise control and a faster response by combining
Main and Auxiliary speed input. Fast response can be achieved via Main speed and
precise control can be accomplished by Aux. speed if the accuracy of Main/Aux speed
is set differently.
Follow the settings shown in the table below when Main speed is given via 0 to 20mA
with Aux. speed via V1 terminal (–10 to 10V).
