Power regeneration converter
Used when the regenerative option cannot provide enough regenerative power.
Can be used for the 5 kW or more servo amplifier.
FR-RC-(H)
power
regeneration
converter
Regenerative option
Used when the built-in regenerative resistor of the servo amplifier does not have sufficient
regenerative capability for the regenerative power generated.
Alarm history clear
Alarm history is cleared.
[Pr. PC21]
Input signal selection (device
settings)
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.
[Pr. PD03] to
[Pr. PD05]
Output signal selection (device
settings)
The output devices including MBR (Electromagnetic brake interlock) can be assigned to certain pins
of the CN3 connector.
[Pr. PD07] to
[Pr. PD09]
Output signal (DO) forced output
Output signal can be forced on/off independently of the servo status.
Use this function for checking output signal wiring, etc.

output
Torque limit
Servo motor torque can be limited to any value.
[Pr. PA11]
[Pr. PA12]
Speed limit
Servo motor speed can be limited to any value.
[Pr. PT67]
Test operation mode
Jog operation, positioning operation, motor-less operation, DO forced output, and program
operation
MR Configurator2 is necessary for this function.
Analog monitor output
Servo status is output in terms of voltage in real time.

PC10]
MR Configurator2
Using a personal computer, you can perform the parameter setting, test operation, monitoring, and
others.
Linear servo system
Linear servo system can be configured using a linear servo motor and linear encoder. For the
software version of the servo amplifier that is compatible, refer to the following.
Page 36 Combinations of servo amplifiers and servo motors
Direct drive servo system
Direct drive servo system can be configured to drive a direct drive motor. For the software version of
the servo amplifier that is compatible, refer to the following.

Fully closed loop system
Fully closed loop system can be configured using the load-side encoder. This is used with servo
amplifiers with software version A1 or later.
One-touch tuning
Gain adjustment is performed just by one click on a certain button on MR Configurator2.
Also, the one-touch tuning can be used through network.
SEMI-F47 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.

[Pr. PF25]
Compliance
with SEMI-F47
standard
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.
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.
• You are using the graph function of MR Configurator2.
• You are using the machine analyzer function.
• [Pr. PF21] is set to "-1".
• The controller is not connected (except the test operation mode).
• An alarm related to the controller is occurring.
