[2] Pulse Train Control Mode (Pulse Train Operation of ERC3)
An operation by pulse train input is available. There are 2 patterns of operation modes,
positioning and pressing.

gear ratio.
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 ERC3 with using a teaching tool such as PC
software.
2) Send pulses based on the moving distance of the actuator to the ERC3 from the PLC
(positioning unit).
3) The ERC3 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.
