Stop function for IEC/EN 61800-5-2
■STO function (Refer to IEC/EN 61800-5-2: 2016 4.2.2.2 STO.)
This is a function of MR-J5 series servo amplifiers.
The STO function shuts off energy to servo motors, thus removing torque. For MR-J5 series servo amplifiers, the energy is
shut off by turning off the power supply electronically in the servo amplifier.
The purpose of this function is as follows.
• Uncontrolled stop according to stop category 0 of IEC/EN 60204-1
• Preventing unexpected restart
■SS1 function (Refer to IEC/EN 61800-5-2: 2016 4.2.2.3C Safe stop 1 temporal delay.)
The SS1 function activates the STO function after the predetermined delay time passes from the start of deceleration. The
delay time can be set with the MR-J3-D05.
The purpose of this function is as follows. This function is available when the MR-J3-D05 and an MR-J5 series servo amplifier
are combined.
• 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: 2016 9.2.5.4.2 Emergency Stop.)
In every operation mode, this must take precedence over all the other functions and operations. Stop category 0 or 1 must
apply to the power supply for the mechanical drive part, which can be the cause of hazardous situations. Even if the cause of
the emergency state has been removed, the power must not be restarted.
■Emergency shut-off (Refer to IEC/EN 60204-1: 2016 9.2.5.4.3 Emergency Switching OFF.)
This shuts off energy to all or part of the equipment when there is a risk of electric shock or any other electrical-based issue.
