Appendix 4 Compliance With Global Standards - Mitsubishi Electric MELSERVO-J4 Series Instruction Manual

Appendix 4
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.
About safety
This chapter explains safety of users and machine operators. Please read the section carefully before mounting the
equipment.
Professional engineer
Only professional engineers should mount MR-J4 servo amplifiers.
Here, professional engineers should meet all the conditions below.
• Persons who took a proper training of related work of electrical equipment or persons who can avoid risk based on past
experience.
• 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.
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 the following 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.
Refer to "MR-D30 Instruction Manual" for the combinations of the servo amplifiers and MR-D30. For the combinations of the
servo amplifiers and MR-J3-D05, refer to the following.

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
• 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.
• It takes 15 minutes maximum for capacitor discharging. Do not touch the unit and terminals immediately after power off.
