LECS installation checklist for manufacturer/installer
The following items must be satisfied by the initial test operation at least. The manufacturer/installer must
be responsible for checking the standards in the items.
Maintain and keep this checklist with related documents of machines to use this for periodic inspection.
1. Is it based on directive/standard applied to the machine? Yes [ ], No [ ]
2. Is directive/standard contained in Declaration of Conformity (DoC)? Yes [ ], No [ ]
3. Does the protection instrument conform to the category required? Yes [ ], No [ ]
4. Are electric shock protective measures (protective class) effective? Yes [ ], No [ ]
5. Is the STO function checked (test of all the shut-off wiring)? Yes [ ], No [ ]
Checking the items will not be instead of the first test operation or periodic inspection by professional
engineers.
App. 5 MR-J3-D05 Safety logic unit of Mitsubishi Electric Corporation
App. 5.1 Terms related to safety
App. 5.1.1 Stop function for IEC/EN 61800-5-2
(1) STO function (Refer to IEC/EN 61800-5-2: 2007 4.2.2.2 STO.)
This function is integrated into the LECSB2-T
□
series drivers.
The STO function shuts down energy to servo motors, thus removing torque. This function
electronically cuts off power supply in drivers for LECSB2-T□ series drivers.
The purpose of this safety function is as follows.
1) Uncontrolled stop according to stop category 0 of IEC/EN 60204-1
2) Preventing unexpected start-up
(2) SS1 function (Refer to IEC/EN 61800-5-2: 2007 4.2.2.3C Safe stop 1 temporal delay.)
SS1 is a function which initiates the STO function when the previously set delay time has passed
after the servo motor starts decelerating. The delay time can be set with MR-J3-D05 of Mitsubishi
Electric Corporation.
The purpose of this safety function is as follows. This function is available by using an LECSB2-T□
series driver with MR-J3-D05 of Mitsubishi Electric Corporation.
Controlled stop according to stop category 1 of IEC/EN 60204-1
App. 5.1.2 Emergency operation for IEC/EN 60204-1
(1) Emergency stop (Refer to IEC/EN 60204-1: 2005 9.2.5.4.2 Emergency Stop.)
Emergency stop must override all other functions and actuation in all operation modes. Power to
the machine driving part which may cause a hazardous state must be either removed immediately
(stop category 0) or must be controlled to stop such hazardous state as soon as possible (stop
category 1). Restart must not be allowed even after the cause of the emergency state has been
removed.
(2) Emergency switching off (Refer to IEC/EN 60204-1: 2005 9.2.5.4.3 Emergency Switching OFF.)
Removal of input power to driving device to remove electrical risk and to meet above mentioned
safety standards.
