1. FUNCTIONS AND CONFIGURATION
1 - 20
Function Description
Detailed
explanation
Auto tuning
Automatically adjusts the gain to optimum value if load applied to the servo motor
shaft varies.
Section 6.3
Brake unit
Used when the regenerative option cannot provide enough regenerative power.
Can be used for the 5 kW or more servo amplifier.
Section 11.3
Power regeneration converter
Used when the regenerative option cannot provide enough regenerative power.
Can be used for the 5 kW or more servo amplifier.
Section 11.4
Regenerative option
Used when the built-in regenerative resistor of the servo amplifier does not have
sufficient regenerative capability for the large regenerative power generated.
Section 11.2
Alarm history clear Alarm history is cleared. [Pr. PC18]
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 any pins. [Pr. PD03] to
[Pr. PD22]
Output signal selection
(device settings) The output devices including MBR (Electromagnetic brake interlock) can be assigned
to certain pins of the CN1 connector.
[Pr. PD23] to
[Pr. PD26]
[Pr. PD28]
[Pr. PD47]
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.
Section 4.5.8
Restart after instantaneous
power failure
If the input power supply voltage had reduced to cause an alarm but has returned to
normal, the servo motor can be restarted by merely switching on the start signal.
(available in the future)
Command pulse selection Command pulse train form can be selected from among three different types. [Pr. PA13]
Torque limit Servo motor torque can be limited to any value.
Section 3.6.1

[Pr. PA11]
[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 outputted 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 or program operation.
Section 4.5.9
Analog monitor output Servo status is output in terms of voltage in real time.
[Pr. PC14],
[Pr. PC15]
MR Configurator2
Using a personal computer, you can perform the parameter setting, test operation,
monitoring, and others.
Section 11.7
Linear servo system
Linear servo system can be configured using a linear servo motor and liner encoder.
This is used with servo amplifiers with software version A5 or later. Check the
software version of the servo amplifier using MR Configurator2.
Chapter 15
Direct drive servo system
The direct drive servo system can be configured to drive a direct drive motor.
This is used with servo amplifiers with software version A5 or later. Check the
software version of the servo amplifier using MR Configurator2.
Chapter 16
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 A5 or later. Check the
software version of the servo amplifier using MR Configurator2.
Chapter 17
One-touch tuning
Gain adjustment is performed just by one click on a certain button on MR
Configurator2 or operation section.
Section 6.2
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. PA20]
[Pr. PE25]
Section 7.4
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.
