8.2 Remote register method
Remote register method of positioning uses the remote register.
Set the position and the speed data by the remote register.
The constant for acceleration and deceleration is the set value of the point table No.1.
This operation is available when two stations are occupied.
Refer to "LECSC Operation Manual", section 3.6.3, section 3.8.4, section 5.4.3 for details of the positioning
operation program for the remote register method.
8.2.1 Positioning operation indication of the remote register method (Example)
(1) Positioning operation indication of the remote register method (Absolute value command system -

It sets the position command data and speed command data in the remote register(Absolute value
command system
– Absolute value command). Turning forward rotation start (RYn1) ON.
Positioning operation start to the

Position data
Position command data lower 16 bit
(RWwn

Set the lower 16 bits of position data
to RWwn
4, and the upper 16 bits to
RWwn
5.
Setting range:
999999 to 999999
Position command data upper 16 bit

Servo motor speed
Speed command data (RWwn
6)
Set the servo motor speed.
Forward rotation start (ST1)
Forward rotation start (RYn1)
Turn RYn1 ON to start.
Set the position data to RWwn 4 / RWwn 5, and the speed command data to RWwn 6, and store them
into the driver.
In the absolute value command system, Absolute value/incremental value selection (RY(n 2)B) can be
used to select whether the values set to the position data are absolute values or incremental values.
The position data set to RWwn 4/RWwn 5 are handled as absolute values when RY(n 2)B is turned
OFF.
The position data set to RWwn 4/RWwn 5 are handled as incremental values when RY(n 2)B is turned
ON.
Turning forward rotation start (RYn1/ST1) ON.
Positioning operation start to the Position data, speed data, acceleration time constant, deceleration time
constant.
