MELSEC-Q

READY

This means that preparation is complete.

REAL-TIME AUTO TUNING (Real-time Automatic Tuning)

Refer to "AUTO TUNING".

REFERENCE AXIS SPEED

This is the speed of the reference axis during interpolation operations.

RLS SIGNAL (reverse limit signal)

This is the input signal that notifies the user that the limit switch (b contact configuration, normally ON) installed at the lower limit of the positioning control enabled range is activated. The positioning operation stops when the RLS signal turns OFF (non-continuity).

ROTARY TABLE

A round table on which the workpiece is placed. Positioning control is carried out while rotating the workpiece in a 360° range.

Y axis speed (interpolation axis)

X axis speed

S-PATTERN ACCELERATION/DECELERATION

In this pattern, the acceleration and

Reference axis speed

REGENERATIVE BRAKE OPTION

This function is an option. It is used when carrying out highly repetitive acceleration/deceleration.

Refer to "EXTERNAL REGENERATIVE RESISTOR".

deceleration follow a sine curve, and the movement is smooth. The S-pattern proportion can be set from 1 to 100%.

Acceleration Deceleration

SERVO AMPLIFIER

Refer to the term "DRIVE UNIT".

RESOLVER

This device detects the angle by resolving the two voltages of the analog input. Also called a 2-phase synchro. For a 1-phase voltage input, the axis rotation angle is converted into a perpendicular 2-phase voltage (analog voltage) and output.
