MR Configurator2
Linear servo system
Analyzes the frequency characteristic of the mechanical system by simply
connecting an MR Configurator2 installed personal computer and servo
amplifier.
MR Configurator2 is necessary for this function.
This function provides better disturbance response in case low response
level that load to motor inertia ratio is high for such as roll send axes.
Suppresses vibration of ±1 pulse generated at a servo motor stop.
Position commands can be multiplied by 1/864 to 33935.
Position commands can be multiplied by 1/9999 to 9999.
Automatically adjusts the gain to optimum value if load applied to the servo
motor shaft varies.
Used when the regenerative option cannot provide enough regenerative
power.
Can be used for the 5 kW or more servo amplifier.
Used when the regenerative option cannot provide enough regenerative
power.
Can be used for the 5 kW or more servo amplifier.
Used when the built-in regenerative resistor of the servo amplifier does not
have sufficient regenerative capability for the regenerative power generated.
Alarm history is cleared.
ST1 (Forward rotation start), ST2 (Reverse rotation start), and SON (Servo-
on) and other input device can be assigned to any pins.
The output devices including MBR (Electromagnetic brake interlock) can be
assigned to certain pins of the CN1 connector.
Output signal can be forced on/off independently of the servo status.
Use this function for checking output signal wiring, etc.
Supports only A-axis/B-axis pulse trains.
Servo motor torque can be limited to any value.
Servo status is shown on the 5-digit, 7-segment LED display
On/off statuses of external I/O signals are shown on the display.
If an alarm has occurred, the corresponding alarm number is outputted in 3-
bit code.
Jog operation/positioning operation/motor-less operation/DO forced
output/program operation/single-step feed
However, MR Configurator2 is necessary for positioning operation, program
operation, and single-step feed.
Servo status is outputted in terms of voltage in real time.
Using a personal computer, you can perform the parameter setting, test
operation, monitoring, and others.
Linear servo system can be configured using a linear servo motor and liner
encoder.
