2 FUNCTION

2.1 Function list
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.
Description
This servo amplifier supports the STO function
for functional safety as per IEC/EN 61800-5-2.
This allows a safety system to be easily
configured for the equipment.
Description
This function uses the electrical energy charged
in the capacitor to avoid triggering [AL. 010
Undervoltage] in case that an instantaneous
power failure occurs during operation. Use a 3-
phase power supply for the input power supply
of the servo amplifier. Using a 1-phase 200 V
AC for the input power supply will not comply
with SEMI-F47 standard.
This function makes the equipment continue
operating even under conditions where an
alarm would normally occur. There are two
types of tough drive function: the vibration tough
drive and the instantaneous power failure tough
drive.
