1. FUNCTIONS AND CONFIGURATION
1 - 9
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 driver.
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 driver.
Section 11.4
Regenerative option
Used when the built-in regenerative resistor of the driver 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
(5)
[Pr. PA11]
[Pr. PA12]
Speed limit
Servo motor speed can be limited to any value.
Section 3.6.3
(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 can be used.
Setup software (MR Configurator2
TM
) 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]
Setup software (MR
Configurator2
TM
)
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 Setup software
(MR Configurator2
TM
) 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 driver. 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.
