Frequency Change Curve
The frequency change curve is a function that controls the acceleration/deceleration frequency. It can be used with the RAMP
pulse output instruction. There are two settings: straight line and S-shaped curve. The straight line setting accelerates and
decelerates at a constant rate when starting and stopping, and this absorbs starting and stopping shocks. The S-shaped curve
setting lessens shocks and reduces vibration by reducing acceleration when starting and stopping. See the description of each
instruction for more information about operations.

Do not reverse the power supply connection under any circumstances. Doing so may damage the components.
When wiring the components, carefully read and understand the manual for the motor driver first.
