Terminology
This Manual uses the following terminology excluding some instances.
Terminology Explanation
Servo amplifier
SV series is the overall system of SV-L (MECHATROLINK-II type) and SV-
P (pulse/analog input type).
Servo motor
SV series is the overall system of SV-M (standard motor) and SV-B
(electromagnetic brake motor).
High-level equipment
This refers to PLC and other controllers which send operation commands to the servo amplifier.
PLC
This refers to the overall system of programmable logic controller mounted in basic unit or CPU unit.
KV-ML16V
This refers to MECHATROLINK-II positioning/motion unit manufactured by KEYENCE
Ltd, which can be connected with KV-5000/3000 PLCs.
KV-MC40V/MC20V
This refers to pulse train type positioning/motion unit manufactured by KEYENCE Ltd.,
which can be connected with KV-5000/3000 PLC.
MECHATROLINK-II
This refers to a type of motion LAN, which allows to build the motion control network with
servo motor inverter, step motor or I/Os. It is omitted to "PLS" in the tables in this Manual.
Pulse/analog input
Operations can be performed via position caommands based on pulse train or speed/torque
commands based on analog inputs. It is omitted to "ML-II" in the tables in this Manual.
CCW This refers to counterclockwise rotation from the output axis end of the servo motor.
CW This refers to clockwise rotation from the output axis end of the servo motor.
ABS Short for absolute encoder.
INC Short for incremental encoder.
Servo latch This refers to the motor stop status when building position loop with position command 0.
Electromagnetic brake
This refers to
the brake equipped on servo motor to perform hold function when powering
OFF.
Dynamic brake stop
(DB stop)
This refers to the stop method which make power terminal short-circuit of servo motor to
achieve emergency stop.
Free-run stop
This refers to the stop method of natural stop via frictional resistance during the motor
rotation without applying braking force to the servo motor.
Regenerative energy
(Regenerative power)
This refers to the rotation energy fed back to servo amplifier load (including servo motor).
Load moment of inertia
This refers to degree of rotation difficulty or degree of stop difficulty of the object. The
larger the load moment of inertia is, the larger the torque required by the object to begin
rotation, additionally, larger regenerative power will be generated at stop.
Tuning
This refers to the characteristic to coordinate with the mechanical system, so response
characteristic of the servo amplifier may be optimized.
Gain
This refers to parameter position control gain or speed control gain etc for adjustment of
follow-up relative to the commands.
Auto tuning This refers to a method of executing auto tuning.
Manual tuning
This refers to a method of executing manual tuning. SV series equipment are equipped
Gain search PRO (w/o higher-level command), Gain search PRO (w/ higher-level
command), Gain tuning PRO and other functions.
