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 continue operation depending on the warning.
This function clears alarm histories.
This function detects a disconnection in the main
circuit power supply input and the servo motor
power supply output.
This function decelerates the servo motor to a
stop at EM2 (Forced stop 2) off or when there is
an alarm.
This function operates the electromagnetic brake
at servo off and error occurrence, and prevents
the vertical axis from dropping.
This function moves the axis up by the
mechanical backlash amount of the
electromagnetic brake to prevent damage to
machines.
