Basic description of PCL series

240 (except for the PCL-240AK/240MK), 50oo (except for the PCL3013/5022), 61oo 60oo
With a normal S-curve, the center point of the
S-curve (point A in Figure 6) has the largest
acceleration rate (a steep slope).
This means that the motor must accelerate
rapidly at this point. So, the stepper motor may
get out-of-step.
PCL series models that have S-curve
acceleration / deceleration can make this
intermediate part a straight line (except for PCD
series and the PCL3013). By providing a straight
line here, the acceleration rate will be smaller
(the slope will be less steep) and an out-of-step
condition can be prevented.
By setting the S-curve range, the length of the
straight line can be set freely.
