App. 5.1 Contents of the package
Open packing, and confirm the content of packing.
App. 5.2 Terms related to safety
App. 5.2.1 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 MR-J4 series servo amplifiers.
The STO function shuts down energy to servo motors, thus removing torque. This function electronically
cuts off power supply in servo amplifiers for MR-J4 series servo amplifiers.
The purpose of this 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.
The purpose of this function is as follows. This function is available by using an MR-J4 series servo
amplifier with MR-J3-D05.
Controlled stop according to stop category 1 of IEC/EN 60204-1
App. 5.2.2 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.
