ACTUAL CURRENT VALUE
Number of pulses for real servo movement,
calculated from the feedback pulses.
ADDRESS
1) The memory address. Many addresses are
stored in the memory. An address is read or
written after it is designated.

2) For positioning, this is a numerical value to
indicate the target position, designated in
mm, inch, angle or No. of pulse units.
Am ACCELERATION
Refers to the maximum value of the cam's
dimensionless acceleration rate.
Refer to the term "A".
ANALOG COMMAND
Converts command pulse to an analog voltage
in positioning unit, and outputs converted
analog voltage to servomotor drive unit.
The motion controller has no dedicated unit
that can command this analog command.
This can be used independently with the
MELSEC-A AD72 or AD70 type analog output
positioning unit.
AUTOMATIC TRAPEZOIDAL
ACCELERATION/DECELERATION
Operation that creates a trapezoidal time and
speed graph during positioning.

AUTO TUNING (Automatic Tuning)
Properties such as responsiveness and
stability of machines driven with a servomotor
are affected by changes in the inertia moment
and rigidity due to changes in the machine
load, etc.
This function automatically adjusts the speed
loop gain and position loop gain to match the
machine state, so the machine's performance
can be maintained at its optimum state.
BACKLASH COMPENSATION
When a forward run operation changes to a
reverse run operation, there is sometimes play
(backlash) in the mesh of the toothed gears.
This also occurs when using a worm gear.
Because of this backlash, a left feed of 1m
carried out after a right feed of 1m will not be
sufficient to return the machine to its original
position. The machine cannot be positioned to
its original position without an extra feed
equivalent to the backlash amount. This is
similar to the "play" of a car's handle.

BACKUP FUNCTION
1) Function that saves the sequence
programs and device states in the PLC
CPU's RAM memory even when the power
is OFF.
2) Function that saves the current value for
the absolute position compatible system
even when the power is OFF.
3) When the CPU unit is replaced, the CPU
data (servo programs, servo parameters,
absolute position compatible data, etc.) are
read out, and reloaded after the CPU is
replaced.
