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".
This function is a functional safety that complies with IEC/EN 61800-5-2. You can
create a safety system for the equipment easily.
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.
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.
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.
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 using MR Configurator2.
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 using MR Configurator2.
The analog input resolution can be increased to 16 bits. This function is available with
MR-J4-_A_-RJ 100 W or more servo amplifiers manufactured in November 2014 or
later.
