APPENDIX
App. - 4
App. 4 Compliance with global standards
App. 4.1 Terms related to safety (IEC 61800-5-2 Stop function)
STO function (Refer to IEC 61800-5-2:2007 4.2.2.2 STO.) The MR-J4 servo amplifiers have the STO
function. The STO function shuts down energy to servo motors, thus removing torque. This function
electronically cuts off power supply in the servo amplifier. In addition, MR-J4-03A6 and MR-J4W2-0303B6
don’t support this function.
App. 4.2 About safety
This section explains safety of users and machine operators. Please read the section carefully before
mounting the equipment.
App. 4.2.1 Professional engineer
Only professional engineers should mount MR-J4 servo amplifiers.
Here, professional engineers should meet the all conditions below.
(1) Persons who took a proper engineering training or qualified persons who are engaged in electrical
equipment
Check if applicable technical training is available at your local Mitsubishi Electric office. Contact your
local sales office for schedules and locations.
(2) Persons who can access operating manuals for the protective devices (e.g. light curtain) connected to
the safety control system. Persons who have read and familiarized himself/herself with the manuals.
App. 4.2.2 Applications of the devices
MR-J4 servo amplifiers comply with the following standards.
IEC/EN 61800-5-1, IEC/EN 61800-3, IEC/EN 60204-1
ISO/EN ISO 13849-1 Category 3 PL d, IEC/EN 62061 SIL CL 2, IEC/EN 61800-5-2 SIL 2 (STO) (Except
for MR-J4-03A6 and MR-J4W2-0303B6)
In addition, MR-J4 servo amplifiers can be used with the MR-D30 functional safety unit, MR-J3-D05 safety
logic unit, or safety PLCs. (except for MR-J4-03A6 and MR-J4W2-0303B6)
App. 4.2.3 Correct use
Always use the MR-J4 servo amplifiers within specifications (voltage, temperature, etc. Refer to section 1.3
for details.). Mitsubishi Electric Co. accepts no claims for liability if the equipment is used in any other way or
if modifications are made to the device, even in the context of mounting and installation.
WARNING
It takes 15 minutes for capacitor discharging. Do not touch the unit and terminals
immediately after power off.
