function
Automatically adjusts the gain to optimum value if load applied to the servo motor shaft
varies.
Use the brake unit when the regenerative option cannot provide sufficient regenerative
capability.
Can be used for the 5 kW or more servo amplifier.
Use the power regeneration converter when the regenerative option cannot provide
sufficient regenerative capacity.
Can be used for the 5 kW or more servo amplifier.
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.
Clears alarm histories.
The input devices including LSP (forward rotation stroke end) and LSN (reverse rotation
stroke end) can be assigned to certain pins of the CN3 connector.
The output devices including MBR (Electromagnetic brake interlock) can be assigned to
certain pins of the CN3 connector.
Turns on/off the output signals forcibly independently of the servo status.
Use this function for checking output signal wiring, etc.
Limits the servo motor torque.
The servo motor speed can be limited.
Jog operation, positioning operation, motor-less operation, DO forced output, and
program operation
MR Configurator2 is necessary for this function.
Outputs servo status with voltage in real time.
Using a personal computer, you can perform the parameter setting, test operation,
monitoring, and others.
Linear servo systems can be configured using a linear servo motor and linear encoder.
Direct drive servo systems 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 a certain button on MR Configurator2.
Also, one-touch tuning can be performed via a network. For details, refer to the MR-J4-
_TM_ Servo Amplifier Instruction Manual for each communication method.
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 of MR Configurator2 by clicking the "Graph" button.
However, the drive recorder is not available when:
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 has occurred.
This amplifier complies with the STO function as functional safety of 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.
Also, the servo amplifier life diagnosis function can be used via a network. For details,
refer to the MR-J4-_TM_ Servo Amplifier Instruction Manual for each communication
method.
