  Linear acceleration/deceleration drive 
 “Linear acceleration/deceleration drive” means the system accelerate to the set drive velocity from start velocity 
in a linear fashion. 
In Set-speed mode, the acceleration counter counts the number of pulses accumulated during the acceleration 
process. When the number of remaining pulses is smaller than that of accumulated pulses, the system will begin to 
decelerate (automatically). In deceleration, the velocity will be lowered to the start value in a linear fashion.   
To perform linear acceleration/deceleration drive, the following parameters should be set: 
z  Range: R; 
z  Acceleration: A; acceleration/deceleration; 
z  Deceleration: D; individually set deceleration (subject to temporary setting); 
z  Start velocity: SV; 
z  Drive velocity: V; 
z  Output pulse number: P, for preset drive (subject to temporary setting) 
Triangle prevention for preset drive 
In preset drive mode with linear acceleration and deceleration, if the number of output pulses is smaller than that 
needed to reach the drive speed through acceleration, a triangle-shape wave will be generated. At the time, the 
triangle prevention function will be activated. 
Triangle prevention function means, in preset drive mode with linear acceleration and deceleration, even if the 
number of output pulse is smaller than needed, the system will stop acceleration and maintain the unchanged 
velocity after the number of pulses consumed during acceleration and deceleration is greater than 1.5 times of the 
total number of output pulses. Therefore, even when the number of output pulse is smaller than one half of that of 
output pulses, the motion will be within the Set-speed domain.
