3.3 Operation in Pulse Train Control Mode (Only for Types up to
750W)
Controller front side can switch over the setting between Pulse Train Control Mode and
Positioner Mode with the switch. 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.

2) Parameter No. 25 PIO pattern = 1
(Battery-less) For Absolute Type Actuator
Positioner Mode
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

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.
• When using in the absolute type such as a battery-less absolute
actuator, turn SW1 on and set Parameter No. 25 to 1 (PIO Pattern 1).
• As it is not available to have operation in the absolute specification
for the index absolute type when DD Motor is controlled with the
pulse train, it is necessary to have operation as the incremental
specification. (Set 0 to Parameter No. 79.).
Also, change the settings of software limit values in Parameter No. 3
and 4 so the operation range gets wider than 0.3mm.
