Speed Multiplier
Speed Multiplier is the parameter which decides the multiplication of the speed parameter such as drive speed or
acceleration/deceleration speed.

Speed parameters such as drive speed, start speed and acceleration/deceleration speed can be set within the range from 1 to 8,000.
If the user sets the larger value than that, the speed multiplier must be raised. When raising the speed multiplier, the user can drive
at high-speed but speed resolution becomes rough. Set the minimum value which covers the range of drive speed.
■
Acceleration Rate
Acceleration Rate is the parameter used as acceleration rate at acceleration in acceleration driving. When setting Deceleration
Value to Accel (default value) in mode setting, this acceleration rate will also be used at deceleration.

If the value for acceleration rate is A, actual acceleration rate is

To perform acceleration driving, as shown in the diagram, four
parameters: initial speed, drive speed, acceleration rate and
deceleration rate must be set. However, if performing symmetry
trapezoidal driving, no need to set deceleration rate.
For instance, if the initial speed 500pps is raised up to 20,000pps in 0.3 seconds, speed parameter should be set as follows:
Acceleration Rate (pps/sec)
＝
(20,000
