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 LECSN2-T□ drivers 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 driver.
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 LECSN2-T
□
drivers.
Here, professional engineers should meet the all 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
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)
LECSN2-T□ drivers can be used with the MR-D30 functional safety unit of Mitsubishi Electric Corporation,
MR-J3-D05 safety logic unit of Mitsubishi Electric Corporation, or safety PLCs.
App. 4.2.3 Correct use
Use the LECSN2-T□ drivers within specifications. Refer to section 1.3 for specifications such as voltage,
temperature, etc. SMC Co. accepts no claims for liability if the equipment is used in any other way or if
