18. MR-J4W2-0303B6 SERVO AMPLIFIER
18 - 6
Function Description
Detailed
explanation
Tough drive function
This function makes the equipment continue operating even under the condition
that an alarm occurs.
MR-J4W2-0303B6 servo amplifier is compatible with vibration tough drive. This is
not compatible with 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 is not available with MR-J4W2-0303B6 servo amplifier.
Servo amplifier life diagnosis
function
Cumulative operation time can be checked. This function get hold of the
replacement time for parts of the servo amplifier including a capacitor before it
malfunctions.
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. 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 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.
Fully closed loop system
This is not available with MR-J4W2-0303B6 servo amplifier.
Scale measurement function
This is not available with MR-J4W2-0303B6 servo amplifier.
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.
