1. FUNCTIONS AND CONFIGURATION
1 - 2
Function Description
Detailed
explanation
Gain switching function
You can switch gains during rotation and during stop, and can use an
input device to switch gains during operation.
"MR-JE-_C
Servo Amplifier
Instruction
Manual"
Advanced vibration
suppression control II
This function suppresses vibration or residual vibration at an arm end.
Machine resonance
suppression filter
This filter function (notch filter) decreases the gain of the specific frequency to
suppress the resonance of the mechanical system.
Shaft resonance suppression
filter
When a load is mounted to the servo motor shaft, resonance by shaft torsion during
driving may generate a mechanical vibration of high frequency. The shaft resonance
suppression filter suppresses the vibration.
Adaptive filter II
The servo amplifier detects mechanical resonance and sets filter characteristics
automatically to suppress mechanical vibration.
Low-pass filter
Suppresses high-frequency resonance which occurs as the servo system response is
increased.
Machine analyzer function
Analyzes the frequency characteristic of the mechanical system by simply
connecting an MR Configurator2 installed personal computer and the servo
amplifier.
MR Configurator2 is necessary for this function.
Robust filter
Improves a disturbance response when a response performance cannot be
increased because of a large load to motor inertia ratio, such as a roll feed axis.

Servo Amplifier
Instruction
Manual"
Slight vibration suppression
control
Suppresses vibration of ±1 pulse generated at a servo motor stop.
Electronic gear
The position control is performed based on a value obtained by multiplying the
position command from the controller by the set electronic gear ratio.
When the position control mode is used, the input pulses can be multiplied by 1/10
to 4000.
When the profile position mode is used, the position commands can be multiplied by
1/27649 to 8484.
S-pattern
acceleration/deceleration time
constant
Enables smooth acceleration and deceleration.
Set S-pattern acceleration/deceleration time constants with [Pr. PC03].
As compared with linear acceleration/deceleration, the acceleration/deceleration
time will be longer for the S-pattern acceleration/deceleration time constants
regardless of command speed.
Auto tuning
Automatically adjusts the gain to optimum value if load applied to the servo motor
shaft varies.
Regenerative option
Use a regenerative option when the built-in regenerative resistor of the servo
amplifier does not have sufficient regenerative capacity for a large regenerative
power generated.
Alarm history clear
Clears alarm histories.
Input signal selection (device
settings)
ST1 (Forward rotation start), ST2 (Reverse rotation start), and SON (Servo-on) and
other input device can be assigned to certain pins of the CN3 connector.
Output signal selection
(device settings)
The output devices including MBR (Electromagnetic brake interlock) can be
assigned to certain pins of the CN3 connector.
Output signal (DO) forced
output
Turns on/off the output signals forcibly independently of the servo status.
Use this function for checking output signal wiring, etc.
Torque limit
Limits the servo motor torque.
Speed limit
Servo motor speed can be limited to any value.
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) is 0 V.
MR Configurator2 is necessary for this function.
Alarm code output
If an alarm has occurred, the corresponding alarm number is outputted in 3-bit code.
"MR-JE-_C
Servo Amplifier
Instruction
Manual"
Test operation mode
Jog operation, positioning operation, motor-less operation, DO forced output, and
program operation
MR Configurator2 is necessary for this function.
MR Configurator2
Using a personal computer, you can perform the parameter setting, test operation,
monitoring, and others.
One-touch tuning
Gain adjustment is performed just by one click on MR Configurator2.
This function is available with MR Configurator2 or via a network.
