Function Description
Detailed
explanation
Alarm history clear
Clears alarm histories.
[Pr. PC21]
Input signal selection (device
settings)
The input devices including PC (proportional control) can be assigned to certain pins
of the CN3 connector.
[Pr. PD03] to
[Pr. PD05]
Output signal selection
(device settings)
The output devices including MBR (Electromagnetic brake interlock) can be assigned
to certain pins of the CN3 connector.
[Pr. PD07] to
[Pr. PD09]
Output signal (DO) forced
output
Turns on/off the output signals forcibly independently of the servo status.
Use this function for checking output signal wiring, etc.
MR-J4-_GF_
section 4.5
Torque limit
Limits the servo motor torque.
[Pr. PA11]
[Pr. PA12]
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.

MR-J4-_GF_
section 4.5
Analog monitor output
Outputs servo status with voltage in real time.
[Pr. PC09]
[Pr. PC10]
MR Configurator2
Using a personal computer, you can perform the parameter setting, test operation,
monitoring, and others.
MR-J4-_GF_
section 11.7
Linear servo system
Linear servo systems can be configured using a linear servo motor and linear
encoder.
MR-J4-_GF_
chapter 14
Direct drive servo system
Direct drive servo systems can be configured to drive a direct drive motor.
MR-J4-_GF_
chapter 15
Fully closed loop system
Fully closed loop system can be configured using the load-side encoder.
MR-J4-_GF_
chapter 16
One-touch tuning
Gain adjustment is performed just by one click on MR Configurator2.
MR-J4-_GF_
section 6.2
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.
MR-J4-_GF_
section 7.4
[Pr. PA20]
[Pr. PF25]
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.
MR-J4-_GF_
section 7.3
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:
1. The graph function of MR Configurator2 is being used.
2. The machine analyzer function is being used.
3. [Pr. PF21] is set to "-1".
[Pr. PA23]
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.
MR-J4-_GF_
chapter 13
Servo amplifier life diagnosis
function
You can check the cumulative energization time and the number of on/off times of the
inrush relay. This 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.
Section 9.4
Power monitoring function
This function calculates the power running energy and the regenerative power from
the data in the servo amplifier such as speed and current. Power consumption and
others are displayed on MR Configurator2.
Machine diagnosis function
From the data in the servo amplifier, this function estimates the friction and vibrational
component of the drive system in the equipment and recognizes an error in the
machine parts, including a ball screw and bearing.
This function is available with MR Configurator2 or via a network.
Section 9.3
MR-J4-_GF_
section 17.5
Scale measurement function
The function transmits position information of a scale measurement encoder to the
controller by connecting the scale measurement encoder in semi closed loop control.
MR-J4-_GF_
section 17.1
Limit switch
External limit switches can be used to limit travel intervals of the servo motor.
