·After changing these parameters, turn OFF the main circuit and control power
supplies, and then turn them ON again to enable the new settings.
·Stop by dynamic brake: Stops by using the dynamic brake (short circuiting its
electrical circuit).
·Coast to a stop: Stops naturally, with no brake, by using the friction resistance
of the servomotor in operation.
·Plug braking: Stops by using plug braking limit torque.
·Zero Clamp Mode: A mode forms a position loop by using the position
reference zero.
·Dynamic brake is an emergency stop function, and one of the general methods to cause a servomotor sudden stop.
·Dynamic brake suddenly stops a servomotor by shorting its electrical circuit.
·If the servomotor is frequently started and stopped by turning the power ON/OFF or using the servo ON signal(/S-ON),
the DB circuit will also be repeatedly operated, degrading the servo drive’s internal elements.
·Use the speed input reference and position reference to control the starting and the stopping of the servomotor.

· This sets the stop torque for when the overtravel signal (P-OT,N-OT) is input.
· The setting unit is a percentage of the rated torque. (the rated torque is 100%)
· The value large enough to be the servomotor maximum torque, 300% is set as the factory setting for plug braking limit
torque. However, the actual output plug braking limit torque is determined by servomotor ratings.
