3.3 Operation in Pulse Train Control Mode
This controller can switch over the setting between Pulse Train Control Mode and Positioner
Mode with the switch on the controller front side. In Pulse Train Mode, the actuator can be
operated by the pulse train output of the host controller (PLC) positioning control function. This
operation mode is not to be changed after the system is complete to be established or during
an operation.

Caution: • SW2 is for manufacturer’s tuning use only. Keep it OFF while in use. Using
the unit with this switch on may cause the controller to malfunction or perform
an unexpected operation.
• In Pulse Train Control Mode, the operation is performed corresponding to the
input pulse.
Input Pulse Value � Moving distance
Input pulse frequency � Velocity
Change in Input Pulse Frequency � Velocity change and acceleration/deceleration
Do not use the actuator above the specifications for the commands of the
movement amount, acceleration and deceleration from the host controller
(PLC). Doing so may cause an abnormal noise or malfunction.
• In Pulse Train Control Mode, the anti-vibration control or pressing operation
using force sensor cannot be performed.
• Pulse train control cannot be performed with Fieldbus type controller.
Selecting Pulse Train Control Mode will issue Alarm 0DD “Drive Mode Error”.
• The actuator equipped with the linear spurious absolute encoder cannot be
controlled with the pulse train.
It will generate Alarm 0DD “Drive Mode Error”.
