Description
This drive unit 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.
This function electrically shuts off the servo
motor driving energy with input signals from
external devices (shut-off by the secondary-side
output). This is equivalent to the stop category 0
of IEC/EN 60204-1.
This function starts deceleration with input
signals from external devices. After the
specified time to confirm the motor stop, the
STO function is executed (SS1). This is
equivalent to the stop category 1 of IEC/EN
60204-1.
This function outputs signals for controlling the
external brake.
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.
