Mitsubishi Electric MR-J4W2-0303B6, Instruction Manual

Page: 520 / 588

APPENDIX
App. - 5
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. The servo
amplifiers without the CN8 connector (such as MR-J4-03A6) do not support this function.
App. 4.2 About safety
This chapter 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 all the conditions below.
(1) Persons who took a proper training of related work of electrical equipment or persons who can avoid risk
based on past experience.
(2) Persons who have read and familiarized himself/herself with this installation guide and operating
manuals for the protective devices (e.g. light curtain) connected to the safety control system.
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 e, IEC/EN 62061 SIL CL 3, IEC/EN 61800-5-2 (STO) (Except for MR-
J4-03A6 and MR-J4W2-0303B6. Refer to section app. 4.8.1 for compatible models.)
MR-J4 servo amplifiers can be used with the MR-D30 functional safety unit, MR-J3-D05 safety logic unit, or
safety PLCs. (For combinations of the servo amplifiers and MR-D30 or MR-J3-D05, refer to each servo
amplifier instruction manual.)
App. 4.2.3 Correct use
Use the MR-J4 servo amplifiers within specifications. Refer to each instruction manual for specifications
such as voltage, temperature, etc. 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 maximum for capacitor discharging. Do not touch the unit and
terminals immediately after power off.
If you need to get close to the moving parts of the machine for inspection or
others, ensure safety by confirming the power off, etc. Otherwise, it may cause an
accident.
