Stop function for IEC/EN 61800-5-2
■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.
• Uncontrolled stop according to stop category 0 of IEC/EN 60204-1
• Preventing unexpected start-up
■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
Emergency operation for IEC/EN 60204-1
■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.
■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.
