Function Description
Machine analyzer Analyzes the frequency characteristic of the mechanical system by simply connecting an MR
function Configurator2 installed personal computer and the servo amplifier.
MR Configurator2 is necessary for this function.
Robust filter Improves a disturbance response when a response performance cannot be increased because of a
large load to motor inertia ratio, such as a roll feed axis.
Slight vibration Suppresses vibration of ±1 pulse generated at a servo motor stop.
suppression control
Electronic gear Positioning control is performed with the position command from the controller multiplied by a set
electronic gear ratio. In the point table mode, position commands can be multiplied by 1/864 to 271470.
In the indexer mode, the position commands can be multiplied by 1/9999 to 9999.
Auto tuning Automatically adjusts the gain to optimum value if load applied to the servo motor shaft varies.
Brake unit Used when the regenerative option cannot provide enough regenerative power.
Can be used for the 5 kW or more servo amplifier.
Power regeneration Used when the regenerative option cannot provide enough regenerative power.
converter Can be used for the 5 kW or more servo amplifier.
Regenerative option Use a regenerative option when the built-in regenerative resistor of the servo amplifier does not have
sufficient regenerative capacity for a large regenerative power generated.
Alarm history clear Clears alarm histories.
Input signal selection The input devices including PC (proportional control (PID control)) can be assigned to certain pins of
(device settings) the CN3 connector.
Output signal selection The output devices including MBR (electromagnetic brake interlock) can be assigned to certain pins of
(device settings) the CN3 connector.
Output signal (DO) Turns on/off the output signals forcibly independently of the servo status.
forced output Use this function for checking output signal wiring, etc.
Torque limit Limits the servo motor torque.
Test operation mode JOG operation, positioning operation, motor-less operation, DO forced output, program operation and
single-step feed can be used.
Note that MR Configurator2 is necessary for positioning operation, program operation, and single-step
feed.
Analog monitor output Outputs servo status with voltage in real time.
MR Configurator2 Using a personal computer, you can perform the parameter setting, test operation, monitoring, and
others.
When using MR Configurator2 with an Ethernet connection, use a servo amplifier with software version
A4 or later and MR Configurator2 with software version 1.70Y or later.
Linear servo system Linear servo systems can be configured using a linear servo motor and linear encoder.
Direct drive servo Direct drive servo systems can be configured to drive a direct drive motor.
system
Fully closed loop system Fully closed loop system can be configured using the load-side encoder.
One-touch tuning Gain adjustment is performed just by one click on MR Configurator2.
SEMI-F47 function This servo amplifier complies with the SEMI-F47 standard. Thus, even when an instantaneous power
failure occurs during operation, the electrical energy charged in the capacitor is used and [AL. 10
Undervoltage] is not triggered.
Tough drive function This function makes the equipment continue operating even under the condition that an alarm occurs.
The tough drive function includes two types: the vibration tough drive and the instantaneous power
failure tough drive.
Drive recorder function This function continuously monitors the servo status and records the status transition before and after
an alarm for a fixed period of time. You can check the recorded data by clicking the Waveform-Display
button on the drive recorder window on MR Configurator2.
However, the drive recorder is not available when:
• The graph function of MR Configurator2 is being used.
• The machine analyzer function is being used.
• [Pr. PF21] is set to "-1".
STO function This function is a functional safety that complies with IEC/EN 61800-5-2. You can create a safety
system for the equipment easily.
Servo amplifier life You can check the cumulative energization time and the number of on/off times of the inrush relay. This
diagnosis function function gives an indication of the replacement time for parts of the servo amplifier including a capacitor
and a relay before they malfunction.
This function is available with MR Configurator2 or via a network.
