Function Description
(Note)
Control mode
Reference
Position control mode This servo is used as position control servo. P
Section 3.2.1
Section 3.6.1
Section 4.2
Speed control mode This servo is used as speed control servo. S
Section 3.2.2
Section 3.6.2
Section 4.3
Torque control mode This servo is used as torque control servo. T
Section 3.2.3
Section 3.6.3
Section 4.4
Position/speed control change
mode Using external input signal, control can be switched between
position control and speed control.
P/S Section 3.6.4
Speed/torque control change
mode Using external input signal, control can be switched between
speed control and torque control.
S/T Section 3.6.5
Torque/position control
change mode Using external input signal, control can be switched between
torque control and position control.
T/P Section 3.6.6
High-resolution encoder
High-resolution encoder of 262144 pulses/rev is used as a
servo motor encoder.
P, S, T
Absolute position detection
system Merely setting a home position once makes home position
return unnecessary at every power-on.
P Chapter 14
Gain changing function
You can switch between gains during rotation and gains
during stop or use an external signal to change gains during
operation.
P, S Section 8.6
Advanced vibration
suppression control This function suppresses vibration at the arm end or residual
vibration.
P Section 8.4
Adaptive filter
Servo amplifier detects mechanical resonance and sets filter
characteristics automatically to suppress mechanical
vibration.
P, S, T Section 8.2
Low-pass filter
Suppresses high-frequency resonance which occurs as servo
system response is increased.
P, S, T Section 8.5
Machine analyzer function
Analyzes the frequency characteristic of the mechanical
system by simply connecting a servo configuration software-
installed personal computer and servo amplifier.
MR Configurator MRZJW3-SETUP221E is necessary for this
function.
P
Machine simulation
Can simulate machine motions on a personal computer
screen on the basis of the machine analyzer results.
MR Configurator MRZJW3-SETUP221E is necessary for this
function.
P
Gain search function
Personal computer changes gains automatically and
searches for overshoot-free gains in a short time.
MR Configurator MRZJW3-SETUP221E is necessary for this
function.
P
Slight vibration suppression
control Suppresses vibration of 1 pulse produced at a servo motor
stop.
P Parameters No. PB24
Electronic gear Input pulses can be multiplied by 1/50 to 50. P
Parameters
No. PA06, PA07
Auto tuning
Automatically adjusts the gain to optimum value if load
applied to the servo motor shaft varies. Higher in
performance than MR-J2-Super series servo amplifier.
P, S Chapter 7
Position smoothing Speed can be increased smoothly in response to input pulse. P Parameter No. PB03
S-pattern acceleration/
deceleration time constant
Speed can be increased and decreased smoothly. S, T Parameter No. PC03
Regenerative option
Used when the built-in regenerative resistor of the servo
amplifier does not have sufficient regenerative capability for
the regenerative power generated.
