APPENDICES
INTERLOCK
In this condition, the machine is blocked from
moving to the next operation until the
operation in progress is complete. This
function is used to prevent damage to devices
and malfunctioning.

INTERPOLATION OPERATION
The operation of two motors simultaneously to
carry out a composite operation. The
positioning distance, acceleration/deceleration
time, speed, etc., for the two motors can be
freely set, but they will be combined to move
the machine in a straight line, circle, etc.
Interpolation operations consist of linear
interpolation and circular interpolation.
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.
JOG
This refers to moving the tool in small steps at
a time. Inching.
Parameter setting is required when carrying
out JOG operation. Note that when this mode
is left ON for long periods, it will be turned OFF
by the stroke limit upper value.
kPPS
This is the abbreviation for "kilopulses per
second". 80kPPS equals 80,000 pulses per
second.

LIMIT SWITCH
This is a switch set to stop a moving object at
both ends, etc., of a movement device for
safety reasons.
A circuit is created in which the moving body
itself presses against the switch to activate the
contact and forcibly shut the power OFF. For
example, pressing on the actuator in the
drawing below activates the internal
microswitch. There are various other types.
Push plunger
Rubber cap
Lead
NC NO COM
LIMIT SWITCH OUTPUT
This function eliminates the need for an
external limit switch by outputting the same
ON/OFF signal as the limit switch. The
ON/OFF signal of the limit switch data
corresponding to the actual current value
address of each axis is output, based on the
data set beforehand for each axis.
LINEAR INTERPOLATION
This automatic operation simultaneously
operates the latitudinal (X) feed and
longitudinal (Y) feed motors to move the
machine in a diagonal line when positioning.
Linear interpolation combining axis 1 and axis
2 is possible with the AD75, but the same
positioning data Nos. must be used. Refer to
the term "INTERPOLATION OPERATION".
