(10) Acceleration/deceleration mode
Define the acceleration/deceleration pattern.
The factory setting is 0.
0: Trapezoid pattern
1: S-motion
2: Primary delay filter
Trapezoid pattern
* Set the acceleration and deceleration in the “Acc” and “Dcl” fields of the position table.
S-motion
The acceleration curve rises gradually at first and then suddenly shoots up in the middle.
Use this mode if you want to set high acceleration/deceleration to meet the required tact time,
but want to move the actuator gradually at the start of movement and immediately before
stopping.
* The S-motion level is set by parameter No. 56 [S-motion ratio setting]. The setting unit is %, while
the setting range is 0 to 100.
(The graph above assumes that the parameter is set to 100%.)
If 0 is set, the S-motion control is disabled.
Note that the setting made here is not reflected in jogging or inching feed performed from a PC or
teaching pendant.
(Note) This setting is not available on ERC2 and PCON (excluding PCON-CA/CFA/CB/CFB)
controllers. On these controllers, parameter No. 56 is reserved.
Primary delay filter
The acceleration/deceleration curve becomes more gradual than linear
acceleration/deceleration (trapezoid pattern).
Use this mode if you don't want to apply fine vibration to the work part during
acceleration/deceleration.
* The primary delay level is set by parameter No. 55 [Primary filter time constant for position
commands]. The setting unit is 0.1 msec, while the setting range is 0.0 to 100.0.
If 0 is set, the primary delay filter is disabled.
Note that the setting made here is not reflected in jogging or inching feed performed from a PC or
teaching pendant.
(Note) This setting is not available on ERC2 and PCON (excluding PCON-CA/CFA/CB/CFB)
controllers. On these controllers, parameter No. 55 is reserved.
