1.1 Function explanation
Description
This function assigns input devices including LSP (forward rotation
stroke end) to certain pins of the connector.
This function assigns output devices including MBR
(Electromagnetic brake interlock) to certain pins of the connector.
This function calculates the running power and the regenerative
power from the data in the servo amplifier such as speed and
current. The power consumption and other values are displayed
on MR Configurator2.
Description
Use this function if the built-in regenerative resistor of the servo
amplifier does not have sufficient regenerative capacity for the
generated regenerative power.
Description
This function displays an alarm or warning when an error occurs
during operation. When an alarm occurs, ALM (Malfunction) turns
off and stops the servo motor. When a warning occurs, WNG
(Warning) will turn on. The servo motor may stop or may continue
operation depending on the warning.
This function clears alarm histories.
This function detects a disconnection in the servo motor power
supply output.
This function decelerates the servo motor to a stop at EM2 off or
when there is an alarm.
This function operates the electromagnetic brake at servo off or
when there is an error, and prevents a vertical axis from dropping.
This function moves the axis up by the mechanical backlash
amount of the electromagnetic brake to prevent machine damage
from occurring.
During the power shut-off and alarm occurrence, this function
shorts between U, V, and W phases and operates the brake.
Description
This function makes the equipment continue operating even under
the condition that an alarm occurs. There are two types of drive in
the tough drive function: the vibration tough drive and the
instantaneous power failure tough drive.
