 Differences in Terms for Rotary Servomotors and Linear Servomotors
There are differences in the terms that are used for Rotary Servomotors and Linear Servomotors.
This manual primarily describes Rotary Servomotors. If you are using a Linear Servomotor, you
need to interpret the terms as given in the following table.
Ter m Meaning
Servomotor A Σ-7-Series Rotary Servomotor or Linear Servomotor.
Rotary Servomotor
A generic term used for a Σ-7-Series Rotary Servomotor (SGM7M, SGM7J, SGM7A, SGM7P,
SGM7G, or SGMMV).
Linear Servomotor
A generic term used for a Σ-7-Series Linear Servomotor (SGLG, SGLF, or SGLT).
SERVOPACK
A Σ-7-Series Σ-7W Servo Amplifier with MECHATROLINK-III Communications References.
Servo Drive
The combination of a Servomotor and SERVOPACK.
Servo System
A servo control system that includes the combination of a Servo Drive with a host controller
and peripheral devices.
servo ON
Supplying power to the motor.
servo OFF
Not supplying power to the motor.
base block (BB)
Shutting OFF the power supply to the motor by shutting OFF the base current to the power
transistor in the SERVOPACK.
servo lock
A state in which the motor is stopped and is in a position loop with a position reference of 0.
Main Circuit Cable
One of the cables that connect to the main circuit terminals, including the Main Circuit Power
Supply Cable, Control Power Supply Cable, and Servomotor Main Circuit Cable.
SigmaWin+
The Engineering Tool for setting up and tuning Servo Drives or a computer in which the Engi-
neering Tool is installed.
active alarm axis The axis on which the alarm is active.
synchronized
stopping axis
The axis that is synchronized to and stopped with the axis on which the alarm is active when
Synchronized Stopping is enabled.
Absolute Encoder
The general term used for absolute encoders with batteries and batteryless absolute encod-
ers.
In cases where the general term causes confusion, the term “batteryless absolute encoder”
may also be used.
