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.
Command pulse train form can be selected from among three different types.
Servo motor torque can be limited to any value.
Servo motor speed 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.
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.
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, and
program operation
MR Configurator2 is required for the positioning operation and program operation.
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.
Gain adjustment is performed just by one click on a certain button on MR
Configurator2 or operation section.
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 on MR Configurator2 by clicking the "Graph" button.
However, the drive recorder will not operate on the following conditions.
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".
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.
This function calculates the power running energy and the regenerative power from
the data in the servo amplifier such as speed and current. Power consumption and
others are displayed on MR Configurator2.
From the data in the servo amplifier, this function estimates the friction and vibrational
component of the drive system in the equipment and recognizes an error in the
machine parts, including a ball screw and bearing.
MR Configurator2 is necessary for this function.
