Glossary
RTEX
RTEX, which stands for Realtime Express, is the network exclusive for motion connecting the Positioning
Unit RTEX and AMP.
* Realtime Express is the name of the network servo system produced by Panasonic.
AMP
AMP means a servo amplifier which controls a servo motor.
Configurator PM
Configurator PM is a setting tool for Positioning Unit RTEX. Using the Configurator PM enables the
settings for positioning data and various parameters, and various monitoring. As a tool operation mode
to activate a motor without using ladder programs is provided in this tool, it is convenient especially to
confirm the operation at the time of an initial start-up.
PANATERM
This is a setup support tool for the servo amplifiers of MINAS series made by Panasonic. By using this
tool, the parameter settings within the AMP, monitoring control statuses, the setup support or analysis of
machines can be executed on PC.
E point control
This is a method of control which is initiated up to an end point, and in this manual is referred to as “E
point control”. This method is used for a single - speed acceleration/deceleration. It is also called a
trapezoidal control.
P point control
This refers to control which passes through a “Pass Point”, and is called “P point control” in this manual.
This method is used when a multi-stage speed is to be specified in the same motion.
vi
C point control
This refers to control which passes through a “Continuance Point”, and is called “C point control” in this
manual. This method is used for executing continuous E point controls by one-time start.
Linear acceleration/deceleration / S acceleration/deceleration
"Linear acceleration/deceleration" or "S acceleration/deceleration" is selectable for the
acceleration/deceleration method. With linear acceleration/deceleration, acceleration and deceleration
between the startup and the target speed are carried out in a straight line. Acceleration and deceleration
take place at a constant percentage.
The S acceleration/deceleration performs acceleration or deceleration curvedly.
Acceleration/deceleration is performed relatively slow at the beginning, and gradually increased.
Acceleration/deceleration is performed slowly as approaching the end of it. The movement is relatively
smooth. Acceleration/deceleration is complete in an acceleration/deceleration time specified in the
shared memory.
vii
Acceleration time/deceleration time
For the E point control or C point control, the acceleration time is the time during which the speed
changes from the startup speed of a motor to the target speed. The deceleration time is the time during
which the speed changes from the target speed to the stop. For the P point control, the acceleration time
is the time during which the speed accelerates form the current speed to the next target speed, and the
deceleration time is the time during which the speed decelerates from the current speed to the next
target speed.
CW, CCW
Generally, these indicate the direction in which the motor is rotating, with CW referring to clockwise
rotation and CCW to counterclockwise rotation.
Absolute method (absolute value control method)
This is a control method in which the target position is specified as an absolute position from the home
position. This is specified on the positioning data editing screen of the Configurator PM.
Increment method (relative value control method)
This is a control method in which the distance from the current position to the target position is specified
as a relative position. This is specified on the positioning data editing screen of the Configurator PM.
Automatic operation
This is an operation to be automatically executed, and means a position control.
Manual operation
This is an operation to be executed for an initial boot or adjustments. The home return, JOG operation
and pulser operation are manual operations.
Position control
This is a generic term for the E point control, P point control and C point control. For each control, the
control of a single axis and the interpolation control of multiple axes are available. The interpolation
control can be selected from a 2-axis linear interpolation, 2-axis circular interpolation, 3-axis linear
interpolation and 3-axis spiral interpolation.
JOG operation
This refers to an operation in which the motor is rotated only while operation commands are being input.
This is used to forcibly rotate the motor using input from an external switch, for instance when to make
adjustments. Depending on the circumstances, this can also be applied to unlimited feeding in some
cases.
viii
Home return
The reference position for positioning is called a Home position and an operation to travel to a Home
position is called Home return. The home position should be set in advance. This operation moves to the
home position and its coordinate is set to be 0.
The motor rotation is reversed automatically when the limit input (+) or the limit input (-) is input and the
home position or the near home position is searched to return to the home position automatically.
Pulser operation
A manual operation is available using a device (pulser) which generates pulses manually. The output
similar to an encoder is obtained from the pulser, and the positioning unit RTEX is equipped with
exclusive input terminals. It is also called a manual pulse generator.
Deceleration stop
This is a function that interrupts the operation in progress, slows the rotation and brings it to a stop. The
deceleration time can be specified individually.
Emergency stop
This is a function that interrupts the operation in progress, slows the rotation and brings it to a stop.
Generally, a time shorter than a time for a deceleration stop is set. The deceleration time can be
specified individually.
Positioning table (Table)
A series of positioning data such as acceleration/deceleration time, target speed and interpolation
operation that is necessary for a position control is managed as a positioning table. For example, one
table is necessary for the E point control, and multiple tables are necessary for the P point control and C
point control depending on the number of pass points and continuance points.
Limit input (+), limit input (-)
This is an input to set a limit the motor movement. Limit input (+) is the maximum limit and the limit input
(-) is the minimum limit. They are connected to the AMP for the positioning unit RTEX.
Near home (DOG) input
In order to stop the table at the home position, a position at which deceleration begins is called the near
home position. This is connected to an external input switch or sensor. It is connected to the AMP for the
positioning unit RTEX.
Dwell time
In case of the E point control, a time from the completion of a position command until the operation done
flag turns on can be specified as a dwell time. In case of the C point control, a time from the deceleration
stop until the next table activates can be specified.
ix
Auxiliary output code, auxiliary output contact
They are used to check the operation of a position control.
The auxiliary output code is a 16-bit code that can be specified for each positioning table, and enables to
monitor which positioning table is being executed.
The execution of the position control can be confirmed by turning an exclusive auxiliary output contact on
for a constant time.
Software limit
Limits in software can be set for the absolute coordinate managed within the positioning unit RTEX.
When exceeding the setting range of the software limit, an error occurs, and the system decelerates and
stops. The deceleration time can be set individually.
Torque limit
The output torque of the AMP can be limited arbitrary.
Servo lock/Servo free
According the command from the positioning unit, the state that the motor is controllable is called a servo
lock state, and the state that the motor is uncontrollable is called a servo free state. The servo on
operation is necessary to make it to the servo lock state.
Servo ON/Servo OFF
The operation that changes the servo free state to the servo lock state is called a servo on, and the
operation that changes the servo lock state to the servo free state is called a servo off.
Linear interpolation
This is the interpolation control that controls positions as the locus of the operations of the 2-axis motor
with the grouped X axis and Y axis or 3-axis motor with the grouped X axis, Y axis and Z axis becomes a
straight line. There are two setting methods, which are a composition speed specification and long axis
speed specification.
Circular interpolation
This is the interpolation control that controls positions as the locus of the operation of the 2-axis motor
with the grouped X axis and Y axis becomes a circular arc. There are two setting methods, which are a
center point specification and pass point specification.
Spiral interpolation
This is the interpolation control that controls positions as the locus of the operation of the 3-axis motor
with the grouped X axis, Y axis and Z axis becomes a spiral. Arbitrary 2 axes describe an arc, and the
remaining one axis moves to achieve a spiral. There are two setting methods, which are a center point
specification and pass point specification.
Edge type
This is one of the methods to detect the request signals allocated to this unit. It executes each requested
process by detecting a trigger that is the leading edge when the request signal turns on.
Therefore, the next request cannot be accepted until the request signal turns off.
Level type
This is one of the methods to detect the request signals allocated to this unit. It executes each requested
process by detecting a trigger that the request signal is on, and continues the requested process while
the request signal is on.
