Note. For details, refer to "MR-J4-_TM_ Servo Amplifier Instruction Manual (EtherCAT)".
Output signal can be forced on/off independently of the servo status.
Use this function for checking output signal wiring, etc.
Servo motor torque can be limited to any value.
Servo motor speed can be limited to any value.
Jog operation, positioning operation, motor-less operation, DO forced output, and
program operation
MR Configurator2 is necessary for this function.
Servo status is output in terms of voltage in real time.
Using a personal computer, you can perform the parameter setting, test operation,
monitoring, and others.
Linear servo system can be configured using a linear servo motor and linear encoder.
Direct drive servo system can be configured to drive a direct drive motor.
Fully closed loop system can be configured using the load-side encoder.
Gain adjustment is performed just by one click on a certain button on MR
Configurator2.
MR Configurator2 is necessary for this function.
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.
Use a 3-phase for the input power supply of the servo amplifier. Using a 1-phase 100
V AC/200 V AC for the input power supply will not comply with SEMI-F47 standard.
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.
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".
4. The controller is not connected (except the test operation mode).
5. An alarm related to the controller is occurring.
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.
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 function sets constant and uniform acceleration/deceleration droop pulses to
almost 0.
