(29) Acceleration/deceleration mode (MOD1, MOD0) [PLC output signal]

These signals are used to select the acceleration/deceleration pattern characteristics. Select a desired mode

before issuing an actuator move command.

MOD1 MOD0 Pattern name Remarks

OFF OFF Trapezoid pattern Factory setting

OFF ON S-motion

ON OFF Primary delay filter

ON ON Not available.

Trapezoid pattern

* The acceleration and deceleration are set in the “Acceleration” and “Deceleration” fields of the

position data table.

S-motion

The actuator accelerates along a curve that increases gradually at first and then rises rapidly in the

middle.

Use this mode if you want to set a high acceleration/deceleration to meet the tact time, but also want the

actuator to accelerate/decelerate gradually at 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 % and the

setting range is 0 to 100.

(The above graph assumes a S-motion ratio of 100 %.)

If “0” is set, the S-motion mode will become invalid.

Take note that this mode will not be reflected in jog or inch operation performed from a PC or

teaching pendant.

Primary delay filter

The acceleration/deceleration curve is more gradual than that of linear acceleration/deceleration

(trapezoid pattern). Use this mode if you don’t want the load to receive micro-vibration during

acceleration/deceleration.

* The primary delay level is set by parameter No. 55, “Primary filter time constant for position

command.” The minimum input unit is 0.1 msec and the setting range is 0.0 to 100.0.

If “0” is set, the primary delay mode will become invalid.

Take note that this mode will not be reflected in jog or inch operation performed from a PC or

teaching pendant.
