Chapter 3 Operation

(2) Pulse Train Control Mode

1) Set the pulse train format and the electric gear ratio (the distance of actuator movement in

mm against 1 pulse) to the parameters in the controller with using a teaching tool such as

PC software.

2) Send pulses based on the moving distance of the actuator to the controller from the PLC

(positioning unit).

3) The controller multiplies the entered number of pulses by the electrical gar ratio to get the

moving distance. The actuator is moved by the moving distance from the current position.

The velocity varies depending on the entered pulse rate (frequency).

4) After the positioning is completed, the completion signal is output.

The above procedure describes the basic operation method in the pulse train control mode.

3.1.2 Parameter Settings

Parameter data should be set to be suit to the system or application. Parameters are variables

to be set to meet the use of the controller in the similar way as settings of the ringtone and

silent mode of a cell phone and settings of clocks and calendars.

(Example)

Soft Stroke Limit

: Set a proper operation range for definition of the stroke end,

prevention of interferences with peripherals and safety.

Zone Output

: Set to require signal outputs in an arbitral position zone within the

operation zone.

Parameters should be set to meet the use of the controller prior to operation. Once set, they

may not set every operation.

Refer to Chapter 8 for the parameter types and the details.
