Specification
Basic function
The motor is operated to estab-
lished the origin.
The position where the motor is
stopped is set to a specified posi-
tion to establish the origin.
The axis is returned to the estab-
lished origin.
The origin is established using a
Servomotor with an absolute
encoder, so origin searches are
not required at machine startup.
The position and speed are speci-
fied to perform positioning using
an absolute or relative movement.
The target position or target
speed is changed during position-
ing with direct operation.
When an interrupt input signal
turns ON during positioning with
direct operation, operation
switches to positioning for a fixed
amount.
The axis is moved at a fixed
speed in the forward rotation or
reverse rotation direction.
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.
The axis command speed is mul-
tiplied by a constant ratio.
A constant limit is applied to the
output torque of the Servomotor
during positioning.
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.
Servo Drive parameters are read
or written from the CPU Unit.
