A - 48
IN POSITION
Signal that relies on the positioning data's
servo parameters. The droop pulse amount in
the deviation counter (difference of position
feedback from position command value and
servomotor) is detected, and if the result
matches the setting value, this signal turns
ON.
This can be used to disregard fractional droop
pulses, and start the next positioning.
INSTALLATION FUNCTION
The OS (operating system) in the motion
controller can be rewritten with a peripheral
device. The OS includes SV13 for the transfer
assembly machine, SVC22 for the automatic
machine, SV43 for the machine tool peripheral
device and SCV41 for the dedicated robot.
Usage that matches each machine can be
realized by installing the OS.
INVERTER
This refers to a device to change a direct
current (DC) to an alternating current (AC).
The device actually changes the motor speed
by changing 50Hz or 60Hz of commercial
frequency to direct current once, then
changing it again to a 5 to 120Hz alternating
current and controlling the motor speed.
JERK
The acceleration rate is differentiated by time
to indicate the acceleration rate change rate.
JOG
This refers to moving the tool in small steps at
a time. Inching.
JOG operation can be carried out with test
operation of a peripheral device, and from the
sequence program by writing in the
parameters and JOG speed.
kPPS
This is the abbreviation for "kilopulses per
second". 80kPPS equals 80,000 pulses per
second.
LINEAR INTERPOLATION
Automatic operation, in which the CPU makes
calculations so that the axis moves along a
straight line when positioning is carried out by
simultaneously operating both the longitudinal
feed and latitudinal feed motors.
The types include ABS-2, INC-2, ABS-4 and
INC-4.
An example of 2-axis linear interpolation is
shown on the right.

LOW-INERTIA MOTOR
This is a motor used when frequent
acceleration/deceleration is repeated. Low-
inertia motors are longitudinally longer, to
decrease the rotor diameter and cover the
torque. This enables their inertia moment to be
reduced up to 1/3 that of standard motors. The
ideal load inertia ratio is 1 or less.
MACHINE NAME (System Name)
This is a sign of up to 8 characters that the
user can choose and assign to a file name.
Alphabetic characters (uppercase), numerals,
and minus (–) signs can be used. The first
character is an alphabetic character.
Refer to the term "FILE NAME".
