1. FUNCTIONS AND CONFIGURATION
1 - 10
Function Description
Detailed
explanation
SEMI-F47 function (Note)
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 200 V AC for the input power supply will not comply with the SEMI-F47
standard.

Section 7.4
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.
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".
4. The controller is not connected (except the test operation mode).
5. An alarm related to the controller is occurring.
[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. Before the parts of the servo amplifier, including a capacitor and
relay, malfunction, this function is useful for finding out the time for their
replacement.
MR Configurator2 is necessary for this function.
Power monitoring function
This function calculates the power running and the regenerative power from the
data, including the speed and current, in the servo amplifier. MR Configurator2 can
display the data, including the power consumption. Since the servo amplifier sends
data to a servo system controller, you can analyze the data and display the data on
a display with the SSCNET III/H system.
Machine diagnostic 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.
Fully closed loop system
Fully closed system can be configured using the load-side encoder. (not available
with the MR-J4 3-axis servo amplifiers)
This is used with servo amplifiers with software version A3 or later. Check the
software version using MR Configurator2.
Chapter 16
Scale measurement function
The function transmits position information of a scale measurement encoder to the
controller by connecting the scale measurement encoder in semi closed loop
control.
Used by servo amplifiers with software version A8 or above. (not available with the
MR-J4 3-axis servo amplifiers)
Section 17.2
J3 compatibility mode
This amplifier has "J3 compatibility mode" which compatible with the previous MR-
J3-B series. Refer to section 17.1 for software versions.
Section 17.1
Continuous operation to
torque control mode
This enables to smoothly switch the mode from position control mode/speed
control mode to torque control mode without stopping. This also enables to
decrease load to the machine and high quality molding without rapid changes in
speed or torque. For details of the continuous operation to torque control mode,
refer to the manuals for servo system controllers.
