A - 53
PULSE RATE (P RATE)
Coefficient that doubles, triples, halves or
thirds the feedback pulses per motor axis
rotation during positioning.
Ratio of the feed pulse and feedback pulse.
For example, if the P rate is set to 2 when the
pulses per rotation are 2400, this will be
equivalent to 1200 pulses. The axis rotation
per pulse for 2400 pulses is 0.15°, but with
1200 pulses, this becomes 0.3°. The
positioning accuracy drops as the P rate
increases.
Refer to the term "ELECTRONIC GEAR".
PULSE TRAIN COMMAND
Positioning control proportional to the number
of pulses can be carried out by continuously
outputting the number of pulses corresponding
to the machine's movement distance from the
motion controller to the servomotor's servo
amplifier.
READY (M9074)
State in which the PCPU or servo amplifier
power has been turned ON and is in the
normal operation state.
REVERSE LIMIT SWITCH
This is the positioning control device input
signal used to notify that the external lower
limit switch (b contact configuration, normally
ON) outside the movement range at which
positioning control is carried out was activated.
The positioning operation stops when the
external RLS signal (b contact) turns OFF
(non-continuity status).
REAL MODE
Refers to directly controlling the servomotor
with the servo program.
REAL-TIME AUTO TUNING (Real-time
Automatic Tuning)
Refer to "AUTO TUNING".
RECIPROCATING CAM
Reciprocating operation, equivalent to the
stroke from the stroke lower limit position
(bottom dead position), is continuously carried
out, allowing extrusion/return operations,
vertical operations, and left/right operations.

REGENERATIVE BRAKE OPTION
This function is an option. It is used when
carrying out highly repetitive
acceleration/deceleration.
Refer to "EXTERNAL REGENERATIVE
RESISTOR".
RESOLVER
This is also called a 2-phase synchronizer.
Compared to the 1-phase voltage input, one
rotation of the axis rotation angle is converted into
a right angle 2-phase voltage (analog) and output.

ROLLER
A cylindrical rotating item that feeds and rolls
paper or steel plates, etc.
The roller output can be set as a virtual mode
output module.
ROTARY TABLE
A round table on which the workpiece is
placed. Positioning control is carried out while
rotating the workpiece in a 360
°
range.
