3.3 Operation in Pulse Train Control Mode (Dedicated for SCON-CA)
SCON-CA 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”.
• It should be the incremental type when having DD motor controlled in the
pulse train control.
Set Parameter No. 79 to 0. Also, change the settings of software limit values
in Parameter No. 3 and 4 so the operation range gets wider than 0.3mm.
