[Pr. PA12]
Speed limit Servo motor speed can be limited to any value.
Section 3.6.3

[Pr. PC05] to
[Pr. PC11]
Status display Servo status is shown on the 5-digit, 7-segment LED display Section 4.5
External I/O signal display On/off statuses of external I/O signals are shown on the display. Section 4.5.7
Automatic VC offset
Voltage is automatically offset to stop the servo motor if it does not come to a stop
when VC (Analog speed command) or VLA (Analog speed limit is 0 V.
Section 4.5.4
Alarm code output If an alarm has occurred, the corresponding alarm number is output in 3-bit code. Chapter 8
Test operation mode
Jog operation, positioning operation, motor-less operation, DO forced output, and
program operation
MR Configurator2 is required to perform positioning operation and program operation.
Section 4.5.9
Analog monitor output Servo status is output in terms of voltage in real time. [Pr. PC14]
MR Configurator2
Using a personal computer, you can perform the parameter setting, test operation,
monitoring, and others.
Section 11.7
One-touch tuning
Gain adjustment is performed just by one click on a certain button on MR
Configurator2 or operation section.
MR Configurator2 is necessary for this function.
Section 6.1
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".
[Pr. PA23]
STO function
This function is a safety function that complies with IEC/EN 61800-5-2. You can create
a safety system for the equipment easily.
Chapter 13
Servo amplifier life diagnostic
function
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.
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.
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.
