Safety sub-function
STO (Safe torque off)
(When functional safety
parameters are not used)
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.
C0
Refer to "USING STO FUNCTION" in the
following manual.
MR-J5D User's Manual (Hardware)
STO (Safe torque off)
(When functional safety
parameters are used)
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.
C0
Refer to "FUNCTIONAL SAFETY" in the
following manual.
MR-J5 User's Manual (Function)
SS1 (Safe stop 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.
C0
SBC (Safe brake control)
This function outputs signals for controlling the
external brake.

Tough drive
SEMI-F47 function
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.
For the MR-J5D_-_G_ drive unit, this
function cannot be used.
Tough drive function
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.
C0
For the MR-J5D_-_G_ drive unit,
instantaneous power failure tough drive
cannot be used.
Refer to "Tough drive function" in the
following manual.
