Description
This function performs settings (such as servo
parameter settings), test operation, and
monitoring with a personal computer.
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.
During the power shut-off and alarm
occurrence, this function shorts between U, V,
and W phases and operates the dynamic brake.
