SEMI-F47 function
This function which complies with the SEMI-F47 standard enables to avoid
triggering [AL. 10 Undervoltage] using the electrical energy charged in the
capacitor in case that an instantaneous power failure occurs during
operation.
This is not available with MR-J4-03A6-RJ servo amplifiers.

[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-J4-03A6-RJ servo amplifiers are not compatible with the instantaneous
power failure tough drive.

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 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 amplifier complies with the STO function as functional safety of IEC/EN
61800-5-2. You can create a safety system for the equipment easily.
This is not available with MR-J4-03A6-RJ servo amplifiers.

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
Limit switch
Limits travel intervals using LSP (Forward rotation stroke end) and LSN
(Reverse rotation stroke end).
S-pattern
acceleration/deceleration
Enables smooth acceleration and deceleration.
Set S-pattern acceleration/deceleration time constants with [Pr. PC03].
Compared with linear acceleration/deceleration, the
acceleration/deceleration time will be longer for the S-pattern
acceleration/deceleration time constants regardless of command speed.
[Pr. PC03]
section 5.2.2
Software limit
Limits travel intervals by address using parameters.
Enables the same function with the limit switch by setting parameters.
Section 7.4
Analog override
Limits a servo motor speed with analog inputs.
A value can be changed from 0% to 200% for a set speed.
Section 2.4
Digital override
A commanded speed multiplied by an override value selected with OVR
(Override selection) will be an actual servo motor speed.
A value can be changed from 0% to 360% for a set speed.
