function
Hot line forced stop 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.
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".
4. The controller is not connected (except the test operation mode).
5. An alarm related to the controller is occurring.
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. Since the servo amplifier sends data to a
servo system controller, you can analyze the data and display the data on a display
with the SSCNET III/H system.
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.
This function allows smooth switching of the mode from the position control mode or
speed control mode to the torque control mode without stopping. This function
eliminates rapid change of speed and torque, contributing to reduction in load to the
machine and high-quality product molding. For details of the continuous operation to
torque control mode, refer to the manuals for servo system controllers.
This function corrects response delays caused when the machine travel direction is
reversed.
When an alarm occurs in the MR-JE-_B servo amplifier, this function enables all the
servo motors connected to normally operating MR-JE-_B servo amplifiers to
decelerate to a stop by transmitting hot line forced stop signals via a controller.
