1. FUNCTIONS AND CONFIGURATION
1 - 23
Function Description
Detailed
explanation
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
on the drive recorder window on MR Configurator2 by clicking the "Graph" button.
However, the drive recorder will not operate on the following conditions.
1. You are using the graph function of MR Configurator2.
2. You are using the machine analyzer function.
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.
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.
MR Configurator2 is necessary for this function.
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.
MR Configurator2 is necessary for this function.
Lost motion compensation
function
This function improves the response delay occurred when the machine moving
direction is reversed. This is used with servo amplifiers with software version B4 or
later. Check the software version of the servo amplifier with MR Configurator2.
Section 7.6
Super trace control
This function sets constant and uniform acceleration/deceleration droop pulses to
almost 0. This is used with servo amplifiers with software version B4 or later. Check
the software version of the servo amplifier with MR Configurator2.
Section 7.7
Mark
detection
Current
position latch
function
When the mark detection signal is turned on, the current position is latched. The
latched data can be read with communication commands.

Interrupt
positioning
function
When MSD (Mark detection) turns on, this function converts the remaining distance to
the travel distance set in [Pr. PT30] and [Pr. PT31] (Mark sensor stop travel distance).
This is available with MR-J4-_A_-RJ servo amplifiers with software version B7 or later.
MR-D01 extension I/O unit
MR-D01 is an extension I/O unit that can extend the input/output signals of MR-J4-
_A_-RJ servo amplifiers.
MR-D01 is available with MR-J4-_A_-RJ servo amplifiers with software version B7 or
later.
MR-D01 cannot be used with MR-J4-03A6(-RJ) servo amplifiers.

Modbus RTU communication
function
The Modbus protocol uses dedicated message frames for the serial communication
between a master and slaves. The dedicated message frames have functions for
reading and writing data, and you can write parameters from servo amplifiers and
check the operation status of the servo amplifiers by using this function. When the
indexer method is used, there are functional restrictions.
This function is supported by MR-J4-_A_-RJ servo amplifiers with a capacity of 100 W
or more manufactured in November, 2014 or later.
This function will be available with MR-J4-03A6-RJ servo amplifiers in the future.

High-resolution analog input
(VC)
The analog input resolution can be increased to 16 bits. This function is available with
servo amplifiers manufactured in November 2014 or later.
This is not available with MR-J4-03A6-RJ servo amplifiers.
