Purpose Category Name Basic function Details
Establishing the
mechanical origin of
the machine Origin deter-
mination Origin search The motor is operated to estab-
lished the origin. 8-2 Origin Search
Operation
Present position preset The position where the motor is
stopped is set to a specified posi-
tion to establish the origin. 8-3 Present Position
Preset
Origin return The axis is returned to the estab-
lished origin. 8-4 Origin Return
Absolute encoder origin The origin is established using a
Servomotor with an absolute
encoder, so origin searches are
not required at machine startup. 8-6 Absolute
Encoder Origin
Point-to-point (PTP)
positioning Position con-
trol Direct operation (abso-
lute movement or relative
movement) The position and speed are speci-
fied to perform positioning using
an absolute or relative movement. 9-4 Using Direct
Operation
Changing the target
position and speed
as required during
positioning Direct operation:
Changing target position
or changing target speed The target position or target
speed is changed during position-
ing with direct operation. 9-4-3 Changing Tar-
get Position
9-4-4 Changing Tar-
get Speed
Performing position-
ing for a specified
distance from an
external input point
during positioning Interrupt feeding When an interrupt input signal
turns ON during positioning with
direct operation, operation
switches to positioning for a fixed
amount. 9-5 Interrupt Feeding
Performing manual
feeding for adjust-
ment or other pur-
pose Jogging The axis is moved at a fixed
speed in the forward rotation or
reverse rotation direction. 10-2 Jogging
Reducing shock

ating Auxiliary
functions Acceleration/decelera-
tion curves Acceleration/deceleration is per-
formed according to the basic
trapezoidal curve (linear accelera-
tion/deceleration), an exponential
curve, or an S-curve, which
greatly helps to reduce mechani-
cal vibration. 7-4 Acceleration and
Deceleration Opera-
tions
Temporarily multiply-
ing the machine's
operating speed by a
constant ratio to per-
form startup adjust-
ments Overrides The axis command speed is mul-
tiplied by a constant ratio. 10-3 Override
Restricting output
torque during con-
trol operations such
as pushing control Torque limit A constant limit is applied to the
output torque of the Servomotor
during positioning. 10-4 Torque Limits
Stopping the device
during operation Stop func-
tion Deceleration stop or
emergency stop The moving axis is decelerated to
a stop or the axis is moved for the
number of pulses remaining in the
deviation counter and then
stopped. 10-9 Stop Functions
Changing the Servo
Drive settings from
the PLC Data transfer
function Reading/writing Servo
parameters Servo Drive parameters are read
or written from the CPU Unit. 5-3 Transferring
