5.6.1 Positioning Mode
①
In order to prevent accidental impact at the end of the stroke, operate the actuator at a low speed
initially. When changing speed or movement, increase the values whilst checking operation
(Change motor speed, acceleration/deceleration time, movement distance values if required).
See
“LECSC Operation Manual (Simplified Edition)”,section 5.6.2 for motor speed configuration.
See “LECSC Operation Manual (Simplified Edition)”,section 5.6.3 for acceleration/deceleration time
configuration.
See“LECSC Operation Manual (Simplified Edition)”,section 5.6.4 for movement distance
configuration.
②
Actuator positioning operates using [Forward (CCW)] and [Reverse (CW)].
(Check wiring and parameters if operation cannot be performed correctly).
When performing positioning operation in the setup software, the rotation direction of the actuator does
not change if you change the setting of parameter PA14 (Rotation direction selection).
The actuator
moves in the direction of [Forward (CCW)] button and [Reverse (CW)] button.
③
Check the command impulse unit (electronic gear enabled).
The electronic gear duty set to PA06/PA07 will be enabled.
See
“LECSC Operation Manual (Simplified Edition)”,section 5.3.4 – “Parameter Values by Actuator
Model” for PA06/PA07 settings for each actuator.
If PA06/PA07 are set to the values in “LECSC Operation Manual (Simplified Edition)”,section 5.3.4–
Parameter Values by Actuator Model, the travel distance of the actuator per 1 pulse will be calculated as
follows.
・

] ( 0.001[mm])
④
If the
“Stroke-end” (LSP, LSN) signal is not configured as ON, an alarm may occur. (When
checked,
the “stroke-end” (LSP, LSN) will be automatically turned ON only when this window is
open.)
