Cyclic synchronous position
mode (csp)
The position control operation performed by a synchronous sequential position command
through network is supported.
(Note)
Cyclic synchronous velocity
mode (csv)
The speed control operation performed by a synchronous sequential speed command
through network is supported.
Cyclic synchronous torque
mode (cst)
The torque control operation performed by a synchronous sequential torque command
through network is supported.
Profile position mode (pp)
The positioning operation performed by an asynchronous end position command through
network is supported.
Profile velocity mode (pv)
The speed control operation performed by an asynchronous speed command through
network is supported.
Profile torque mode (tq)
The torque control operation performed by an asynchronous torque command through
network is supported.
Homing mode (hm)
The home position return operation specified in each network is supported.
Point table mode (pt)
Set 1 to 255 point tables in advance, and select any point table to perform operation in
accordance with the set values.
This is available with drivers with software version B2 or later.
Chapter 16
Indexer mode (idx)
Set the station positions divided into 2 to 255 in advance to perform operation to the
station positions.
This is available with drivers with software version B2 or later.
Chapter 17
Jog mode (jg)
This is a control mode where the servo motor speed is set to drive the servo motor
manually.
This is available with drivers with software version B2 or later.
Chapter 16,
Chapter 17
Model adaptive control
This function achieves a high response and stable control following the ideal model. The
two-degrees-of-freedom model adaptive control enables you to set a response to the
command and response to the disturbance separately.
Additionally, this function can be disabled. Refer to section 7.5 for disabling this function.
Touch probe
When the touch probe signal turns on, the current position is latched.

(Note)
High-resolution encoder
High-resolution encoder of 4194304 pulses/rev is used for the encoder of the rotary servo
motor compatible with the MELSERVO-J4 series.
Absolute position detection
system
Setting a home position once makes home position return unnecessary at every power-on.
Chapter 12
Gain switching function
You can switch gains during rotation/stop, and can use input devices to switch gains
during operation.
Section 7.2
Advanced vibration
suppression control II
This function suppresses vibration at an arm end or residual vibration.
Section 7.1.5
Machine resonance
suppression filter
This filter function (notch filter) decreases the gain of the specific frequency to suppress
the resonance of the mechanical system.
Section 7.1.1
Shaft resonance suppression
filter
When a load is mounted to the servo motor shaft, resonance by shaft torsion during
driving may generate a mechanical vibration at high frequency. The shaft resonance
suppression filter suppresses the vibration.
Section 7.1.3
Adaptive filter II
The driver detects mechanical resonance and sets filter characteristics automatically to
suppress mechanical vibration.
Section 7.1.2
Low-pass filter
Suppresses high-frequency resonance which occurs as the servo system response is
increased.
Section 7.1.4
