Function
Drive recorder function
Power monitoring function
Machine diagnosis function
Lost motion compensation
function
Note. For servo system controllers which are available with this, contact your local sales office.
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. PX30] is set to "-1".
4. The controller is not connected (except the test operation mode).
5. An alarm related to the controller is occurring.
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 in the system of SSCNET III/H. Since the
servo amplifier sends data to a servo system controller, you can analyze the data and
display the data on a display.
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.
