5.3.4 Positioning Operation
First, change the position complete (PEND) signal bit to “1” by turning on the 24-VDC power by referring to 5.3.2.
Home return is not yet complete immediately after the power has been turned on. Accordingly, home return
operation must be performed using the home return command (HOME) as explained in 5.3.3.
When positioning operation is started (using the CSTR signal) after specifying a position (via position number
specification or direct position data specification), the actuator will perform home return operation and then move
to the specified position.
An example of performing positioning operation using an actuator with a 400-mm stroke is explained below.
Example of position table
*T1: Set to T1 t 0 (ms) by considering the scan time of the host controller.
